Scenario Modeling of Sustainable Development of Energy Supply in the Arctic
Dec 2021
Publication
The 21st century is characterized not only by large-scale transformations but also by the speed with which they occur. Transformations—political economic social technological environmental and legal-in synergy have always been a catalyst for reactions in society. The field of energy supply like many others is extremely susceptible to the external influence of such factors. To a large extent this applies to remote (especially from the position of energy supply) regions. The authors outline an approach to justifying the development of the Arctic energy infrastructure through an analysis of the demand for the amount of energy consumed and energy sources taking into account global trends. The methodology is based on scenario modeling of technological demand. It is based on a study of the specific needs of consumers available technologies and identified risks. The paper proposes development scenarios and presents a model that takes them into account. Modeling results show that in all scenarios up to 50% of the energy balance in 2035 will take gas but the role of carbon-free energy sources will increase. The mathematical model allowed forecasting the demand for energy types by certain types of consumers which makes it possible to determine the vector of development and stimulation of certain types of resources for energy production in the Arctic. The model enables considering not only the growth but also the decline in demand for certain types of consumers under different scenarios. In addition authors’ forecasts through further modernization of the energy sector in the Arctic region can contribute to the creation of prerequisites that will be stimulating and profitable for the growth of investment in sustainable energy sources to supply consumers. The scientific significance of the work lies in the application of a consistent hybrid modeling approach to forecasting demand for energy resources in the Arctic region. The results of the study are useful in drafting a scenario of regional development taking into account the Sustainable Development Goals as well as identifying areas of technology and energy infrastructure stimulation.
Hydrogen Research: Technology First, Society Second?
Jul 2021
Publication
Hydrogen futures are in the making right in front of our eyes and will determine socio-ecological path dependencies for decades to come. However expertise on the societal effects of the hydrogen transition is in its infancy. Future energy research needs to include the social sciences humanities and interdisciplinary studies: energy cultures have to be examined as well as power relations and anticipation processes since the need for (green) hydrogen is likely to require a massive expansion of renewable energy plants.
Hydrogen Production Possibilities in Slovak Republic
Mar 2022
Publication
Slovak Republic is a member of the European Union and is a part of the European energy market. Although Slovakia contributes only marginally to global emissions there is an effort to meet obligations from the Paris climate agreement to reduce greenhouse gases. As in many countries power industry emissions dominate Slovakia’s emissions output but are partly affected and lowered by the share of nuclear energy. The transition from fossil fuels to renewables is supported by the government and practical steps have been taken to promote the wide use of renewable resources such as biomass or solar energy. Another step in this transition process is the support of new technologies that use hydrogen as the primary energy source. The European Union widely supports this effort and is looking for possible sources for hydrogen generation. One of the main renewable resources is hydropower which is already used in the Slovak Republic. This article presents the current situation of the energy market in Slovakia and possible developments for future hydrogen generation.
Influence of Hydrogen on Grid Investments for Smart Microgrids
Mar 2022
Publication
Electrification of the heat network in buildings together with a rise in popularity of Electric Vehicles (EVs) will result in a need to make investments in the electrical energy infrastructure in order to prevent congestion. This paper discusses the influence of hydrogen in future smart microgrids on these investments. Moreover smart control strategies i.e. EV management and demand response programs are used in this paper to lower the peak of electrical energy demand resulting in the reduction of these investments. Performances of microgrid with different levels of hydrogen penetration are discussed. It is shown that an increase in the level of hydrogen in the microgrid will reduce the electric grid investments costs but is not economically more beneficial than using ‘green’ gas due to the higher total economic costs.
Benefits of an Integrated Power and Hydrogen Offshore Grid in a Net-zero North Sea Energy System
Jun 2022
Publication
The North Sea Offshore Grid concept has been envisioned as a promising alternative to: 1) ease the integration of offshore wind and onshore energy systems and 2) increase the cross-border capacity between the North Sea region countries at low cost. In this paper we explore the techno-economic benefits of the North Sea Offshore Grid using two case studies: a power-based offshore grid where only investments in power assets are allowed (i.e. offshore wind HVDC/HVAC interconnectors); and a power-and-hydrogen offshore grid where investments in offshore hydrogen assets are also permitted (i.e. offshore electrolysers new hydrogen pipelines and retrofitted natural gas pipelines). In this paper we present a novel methodology in which extensive offshore spatial data is analysed to define meaningful regions via data clustering. These regions are incorporated to the Integrated Energy System Analysis for the North Sea region (IESA-NS) model. In this optimization model the scenarios are run without any specific technology ban and under open optimization. The scenario results show that the deployment of an offshore grid provides relevant cost savings ranging from 1% to 4.1% of relative cost decrease (2.3 bn € to 8.7 bn €) in the power-based and ranging from 2.8% to 7% of relative cost decrease (6 bn € to 14.9 bn €) in the power-and-hydrogen based. In the most extreme scenario an offshore grid permits to integrate 283 GW of HVDC connected offshore wind and 196 GW of HVDC meshed interconnectors. Even in the most conservative scenario the offshore grid integrates 59 GW of HVDC connected offshore wind capacity and 92 GW of HVDC meshed interconnectors. When allowed the deployment of offshore electrolysis is considerable ranging from 61 GW to 96 GW with capacity factors of around 30%.
A Flexible Techno-economic Analysis Tool for Regional Hydrogen Hubs - A Case Study for Ireland
Apr 2023
Publication
The increasing urgency with which climate change must be addressed has led to an unprecedented level of interest in hydrogen as a clean energy carrier. Much of the analysis of hydrogen until this point has focused predominantly on hydrogen production. This paper aims to address this by developing a flexible techno-economic analysis (TEA) tool that can be used to evaluate the potential of future scenarios where hydrogen is produced stored and distributed within a region. The tool takes a full year of hourly data for renewables availability and dispatch down (the sum of curtailment and constraint) wholesale electricity market prices and hydrogen demand as well as other user-defined inputs and sizes electrolyser capacity in order to minimise cost. The model is applied to a number of case studies on the island of Ireland which includes Ireland and Northern Ireland. For the scenarios analysed the overall LCOH ranges from V2.75e3.95/kgH2. Higher costs for scenarios without access to geological storage indicate the importance of cost-effective storage to allow flexible hydrogen production to reduce electricity costs whilst consistently meeting a set demand.
Decarbonizing China’s Energy System – Modeling the Transformation of the Electricity, Transportation, Heat, and Industrial Sectors
Nov 2019
Publication
Growing prosperity among its population and an inherent increasing demand for energy complicate China’s target of combating climate change while maintaining its economic growth. This paper therefore describes three potential decarbonization pathways to analyze different effects for the electricity transport heating and industrial sectors until 2050. Using an enhanced version of the multi-sectoral open-source Global Energy System Model enables us to assess the impact of different CO2 budgets on the upcoming energy system transformation. A detailed provincial resolution allows for the implementation of regional characteristics and disparities within China. Conclusively we complement the model-based analysis with a quantitative assessment of current barriers for the needed transformation. Results indicate that overall energy system CO2 emissions and in particular coal usage have to be reduced drastically to meet (inter-) national climate targets. Specifically coal consumption has to decrease by around 60% in 2050 compared to 2015. The current Nationally Determined Contributions proposed by the Chinese government of peaking emissions in 2030 are therefore not sufficient to comply with a global CO2 budget in line with the Paris Agreement. Renewable energies in particular photovoltaics and onshore wind profit from decreasing costs and can provide a more sustainable and cheaper energy source. Furthermore increased stakeholder interactions and incentives are needed to mitigate the resistance of local actors against a low-carbon transformation.
Towards a 100% Hydrogen Domestic Gas Network: Regulatory and Commercial Barriers to the First Demonstrator Project in the United Kingdom
May 2022
Publication
In the debate on the decarbonisation of heat renewable electricity tends to play a much more dominant role than green gases despite the potential advantages of gas in terms of utilising existing transportation networks and end-use appliances. Informed comparisons are hampered by information asymmetry; the renewable electricity has seen a huge grid level deployment whereas low-carbon hydrogen or bio-methane have been limited to some small stand-alone trials. This paper explores the regulatory and commercial challenges of implementing the first UK neighbourhood level 100% low-carbon hydrogen demonstration project. We draw on existing literature and action research to identify the key practical barriers currently hindering the ability of strategically important actors to accelerate the substitution of natural gas with low carbon hydrogen in local gas networks. This paper adds much needed contextual depth to existing generic and theoretical understandings of low-carbon hydrogen for heat transition feasibility. The learnings from pilot projects about the exclusion of hydrogen calorific value from the Local Distribution Zone calorific value calculation Special Purpose Vehicle companies holding of liability and future costs to consumers need to be quickly transferred into resilient operational practice or gas repurposing projects will continue to be less desirable than electrification using existing regulations and with more rapid delivery
Low-cost Hydrogen in the Future European Electricity System – Enabled by Flexibility in Time and Space
Nov 2022
Publication
The present study investigates four factors that govern the ability to supply hydrogen at a low cost in Europe: the scale of the hydrogen demand; the possibility to invest in large-scale hydrogen storage; process flexibility in hydrogen-consuming industries; and the geographical areas in which hydrogen demand arises. The influence of the hydrogen demand on the future European zero-emission electricity system is investigated by applying the cost-minimising electricity system investment model eNODE to hydrogen demand levels in the range of 0–2500 TWhH2. It is found that the majority of the future European hydrogen demand can be cost-effectively satisfied with VRE assuming that the expansion of wind and solar power is not hindered by a lack of social acceptance at a cost of around 60–70 EUR/MWhH2 (2.0–2.3 EUR/kgH2). The cost of hydrogen in Europe can be reduced by around 10 EUR/MWhH2 if the hydrogen consumption is positioned strategically in regions with good conditions for wind and solar power and a low electricity demand. The cost savings potential that can be obtained from full temporal flexibility of hydrogen consumption is 3-fold higher than that linked to strategic localisation of the hydrogen consumption. The cost of hydrogen per kg increases and the value of flexibility diminishes as the size of the hydrogen demand increases relative to the traditional demand for electricity and the available VRE resources. Low-cost hydrogen is thus achieved by implementing efficiency and flexibility measures for hydrogen consumers as well as increasing acceptance of VRE.
Political Economy of Green Hydrogen Rollout: A Global Perspective
Dec 2021
Publication
The present paper dwells on the role of green hydrogen in the transition towards climateneutral economies and reviews the central challenges for its emancipation as an economically viable source of energy. The study shows that countries with a substantial share of renewables in the energy mix advanced natural gas pipeline infrastructure and an advanced level of technological and economic development have a comparative advantage for the wider utilization of hydrogen in their national energy systems. The central conclusion this review paper is that a green hydrogen rollout in the developed and oil-exporting developing and emerging countries is not a risk for the rest of the world in terms of the increasing technological disparities and conservation of underdevelopment and concomitant socio-economic problems of the Global South. The targets anchored in Paris Agreement but even more in the EU Green Deal and the European Hydrogen Strategy will necessitate a substantial rollout of RESs in developing countries and especially in the countries of the African Union because of the prioritization of the African continent within the energy cooperation frameworks of the EU Green Deal and the EU Hydrogen Strategy. Hence the green hydrogen rollout will bridge the energy transition between Europe and Africa on the one hand and climate and development targets on the other.
Hydrogen Strategy Update to the Market: July 2022
Jul 2022
Publication
Low carbon hydrogen is our new home-grown super-fuel which will be vital for our energy security and to meet our legally binding commitment to achieve net zero by 2050. The UK Hydrogen Strategy published in August 2021 outlined a comprehensive roadmap for the development of a thriving UK hydrogen economy over the coming decade. In the British Energy Security Strategy published in April this year the government doubled the UK’s hydrogen production ambition to up to 10GW by 2030. This increased ambition cements our place firmly at the forefront of the global race to develop hydrogen as a secure low carbon replacement for fossil fuels in the transition to greater energy security and net zero. Since the publication of the UK Hydrogen Strategy we have continued to deliver on our commitments setting out new policy and funding for hydrogen across the value chain and bringing together the international community around shared hydrogen objectives to rapidly develop a global hydrogen economy. Hydrogen was a key component of the Net Zero Strategy COP26 and the British Energy Security Strategy. The Hydrogen Investment Package and opening of the £240 million Net Zero Hydrogen Fund in April marked a major step forward in delivering government support to drive further private investment into hydrogen production in the UK. To keep industry informed on the government’s ongoing work to develop the hydrogen economy we committed in the UK Hydrogen Strategy to producing regular updates to the market as our policy develops. In addition to offering an accessible ‘one stop shop’ of government policy development and support schemes these updates will provide industry and investors with further clarity on the direction of travel of hydrogen policy across the value chain so that government and industry can work together most effectively and with the necessary pace to build a world-leading low carbon hydrogen sector in the UK.
Clean Hydrogen Is a Challenge for Enterprises in the Era of Low-Emission and Zero-Emission Economy
Jan 2023
Publication
Hydrogen can be considered an innovative fuel that will revolutionize the energy sector and enable even more complete use of the potential of renewable sources. The aim of the paper is to present the challenges faced by companies and economies that will produce and use hydrogen. Thanks to the use of hydrogen in the energy transport and construction sectors it will be possible to achieve climate neutrality by 2050. By 2050 global demand for hydrogen will increase to 614 million metric tons a year and thanks to the use of hydrogen in energy transport and construction it will be possible to achieve climate neutrality. Depending on the method of hydrogen production the processes used and the final effects several groups can be distinguished marked with different colors. It is in this area of obtaining friendly hydrogen that innovative possibilities for its production open up. The costs of hydrogen production are also affected by network fees national tax systems availability and prices of carbon capture utilization and storage installations energy consumption rates by electrolyzers and transport methods. It is planned that 1 kg of hydrogen will cost USD 1. The study used the desk research method which made it possible to analyze a huge amount of descriptive data and numerical data.
Estimation of the Levelized Cost of Nuclear Hydrogen Production from Light Water Reactors in the United States
Aug 2022
Publication
In June 2021 the United States (US) Department of Energy (DOE) hosted the first-ever Hydrogen Shot Summit which lasted for two days. More than 3000 stockholders around the world were convened at the summit to discuss how low-cost clean hydrogen production would be a huge step towards solving climate change. Hydrogen is a dynamic fuel that can be used across all industrial sectors to lower the carbon intensity. By 2030 the summit hopes to have developed a means to reduce the current cost of clean hydrogen by 80%; i.e. to USD 1 per kilogram. Because of the importance of clean hydrogen towards carbon neutrality the overall DOE budget for Fiscal Year 2021 is USD 35.4 billion and the total budget for DOE hydrogen activities in Fiscal Year 2021 is USD 285 million representing 0.81% of the total DOE budget for 2021. The DOE hydrogen budget of 2021 is estimated to increase to USD 400 million in Fiscal Year 2022. The global hydrogen market is growing and the US is playing an active role in ensuring its growth. Depending on the electricity source used the electrolysis of hydrogen can have no greenhouse gas emissions. When assessing the advantages and economic viability of hydrogen production by electrolysis it is important to take into account the source of the necessary electricity as well as emissions resulting from electricity generation. In this study to evaluate the levelized cost of nuclear hydrogen production the International Atomic Energy Agency Hydrogen Economic Evaluation Program is used to model four types of LWRs: Exelon’s Nine Mile Point Nuclear Power Plant (NPP) in New York; Palo Verde NPP in Arizona; Davis-Besse NPP in Ohio; and Prairie Island NPP in Minnesota. Each of these LWRs has a different method of hydrogen production. The results show that the total cost of hydrogen production for Exelon’s Nine Mile Point NPP Palo Verde NPP Davis-Besse NPP and Prairie Island NPP was 4.85 ± 0.66 4.77 ± 1.36 3.09 ± 1.19 and 0.69 ± 0.03 USD/kg respectively. These findings show that among the nuclear reactors the cost of nuclear hydrogen production using Exelon’s Nine Mile Point NPP reactor is the highest whereas the cost of nuclear hydrogen production using the Prairie Island NPP reactor is the lowest.
Economic Feasibility of Green Hydrogen in Providing Flexibility to Medium-voltage Distribution Grids in the Presence of Local-heat Systems
Nov 2022
Publication
The recent strong increase in the penetration of renewable energy sources (RESs) in medium-voltage distribution grids (MVDNs) has raised the need for congestion management in such grids as they were not designed for this new condition. This paper examines to what extent producing green hydrogen through electrolyzers can profitably contribute to congestion alleviation in MVDNs in the presence of high amounts of RES as well as flexible consumers of electricity and a local heat system. To address this issue an incentive-based method for improving flexibility in MVDNs is used which is based on a single-leader–multiple-followers game formulated by bi-level mathematical programming. At the upper level the distribution system operator who is the leader of this game determines dynamic prices as incentives at each node based on the levels of generation and load. Next at the lower level providers of flexibility including producers using electrolyzers price-responsive power consumers heat consumers as well as heat producers respond to these incentives by reshaping their output and consumption patterns. The model is applied to a region in the North of The Netherlands. The obtained results demonstrate that converting power to hydrogen can be an economically efficient way to reduce congestion in MVDNs when there is a high amount of RES. However the economic value of electrolyzers as providers of flexibility to MVDNs decreases when more other options for flexibility provision exist.

Potential of Power-to-Methane in the EU Energy Transition to a Low Carbon System Using Cost Optimization
Oct 2018
Publication
Power-to-Methane (PtM) can provide flexibility to the electricity grid while aiding decarbonization of other sectors. This study focuses specifically on the methanation component of PtM in 2050. Scenarios with 80–95% CO2 reduction by 2050 (vs. 1990) are analyzed and barriers and drivers for methanation are identified. PtM arises for scenarios with 95% CO2 reduction no CO2 underground storage and low CAPEX (75 €/kW only for methanation). Capacity deployed across EU is 40 GW (8% of gas demand) for these conditions which increases to 122 GW when liquefied methane gas (LMG) is used for marine transport. The simultaneous occurrence of all positive drivers for PtM which include limited biomass potential low Power-to-Liquid performance use of PtM waste heat among others can increase this capacity to 546 GW (75% of gas demand). Gas demand is reduced to between 3.8 and 14 EJ (compared to ∼20 EJ for 2015) with lower values corresponding to scenarios that are more restricted. Annual costs for PtM are between 2.5 and 10 bln€/year with EU28’s GDP being 15.3 trillion €/year (2017). Results indicate that direct subsidy of the technology is more effective and specific than taxing the fossil alternative (natural gas) if the objective is to promote the technology. Studies with higher spatial resolution should be done to identify specific local conditions that could make PtM more attractive compared to an EU scale.

Financing Efficiency Evaluation and Influencing Factors of Hydrogen Energy Listed Enterprises in China
Jan 2022
Publication
Existing studies of financing efficiency concentrate on capital structure and a single external environment or internal management characteristic. Few of the studies include the internal and external financing environments at the same time for hydrogen energy industry financing efficiency. This paper used the data envelopment analysis (DEA) model and the Malmquist index to measure the financing efficiency of 70 hydrogen energy listed enterprises in China from 2014 to 2020 from both static and dynamic perspectives. Then a tobit model was constructed to explore the influence of external environment and internal factors on the financing efficiency. The contributions of this paper are studying the internal and external financing environments and integrating financing cost efficiency and capital allocation efficiency into the financing efficiency of hydrogen energy enterprises. The results show that firstly the financing efficiency of China’s hydrogen energy listed enterprises showed an upward trend during the years 2014–2020. Secondly China’s hydrogen energy enterprises mainly gather in the eastern coastal areas and their financing efficiency is more than that in western areas. Thirdly the regional economic development level enterprise scale financing structure capital utilization efficiency and profitability have significant effects on the financing efficiency. These results can promote the achievement of “carbon neutrality” in China.
A Step towards the Hydrogen Economy—A Life Cycle Cost Analysis of A Hydrogen Refueling Station
May 2017
Publication
This study was aimed to define a methodology based on existing literature and evaluate the levelized cost of hydrogen (LCOH) for a decentralized hydrogen refueling station (HRS) in Halle Belgium. The results are based on a comprehensive data collection along with real cost information. The main results indicated that a LCOH of 10.3 €/kg at the HRS can be reached over a lifetime of 20 years if an average electricity cost of 0.04 €/kWh could be achieved and if the operating hours are maximized. Furthermore if the initial capital costs can be reduced by 80% in the case of direct subsidy the LCOH could even fall to 6.7 €/k
Mapping Australia's Hydrogen Future and release of the Hydrogen Economic Fairways Tool
Apr 2021
Publication
Hydrogen can be used for a variety of domestic and industrial purposes such as heating and cooking (as a replacement for natural gas) transportation (replacing petrol and diesel) and energy storage (by converting intermittent renewable energy into hydrogen). The key benefit of using hydrogen is that it is a clean fuel that emits only water vapour and heat when combusted.
To support implementation of the National Hydrogen Strategy Geoscience Australia in collaboration with Monash University are releasing the Hydrogen Economic Fairways Tool (HEFT). HEFT is a free online tool designed to support decision making by policymakers and investors on the location of new infrastructure and development of hydrogen hubs in Australia.

Energy System Modelling of Carbon-Neutral Hydrogen as an Enabler of Sectoral Integration within a Decarbonization Pathway
Jul 2019
Publication
This paper explores the alternative roles hydrogen can play in the future European Union (EU) energy system within the transition towards a carbon-neutral EU economy by 2050 following the latest policy developments after the COP21 agreement in Paris in 2015. Hydrogen could serve as an end-use fuel a feedstock to produce carbon-neutral hydrocarbons and a carrier of chemical storage of electricity. We apply a model-based energy system analysis to assess the advantages and drawbacks of these three roles of hydrogen in a decarbonized energy system. To this end the paper quantifies projections of the energy system using an enhanced version of the PRIMES energy system model up to 2050 to explore the best elements of each role under various assumptions about deployment and maturity of hydrogen-related technologies. Hydrogen is an enabler of sectoral integration of supply and demand of energy and hence an important pillar in the carbon-neutral energy system. The results show that the energy system has benefits both in terms of CO2 emission reductions and total system costs if hydrogen technology reaches high technology readiness levels and economies of scale. Reaching maturity requires a significant investment which depends on the positive anticipation of market development. The choice of policy options facilitating visibility by investors is the focus of the modelling in this paper.
Future Electricity Series Part 2 - Power from Renewables
Sep 2013
Publication
The independent cross-party report highlights a ‘sensible middle ground’ in the renewables debate and calls for more effort in building cross-party consensus. It finds that the UK has only just begun to harness low carbon renewable resources bigger than North Sea oil and gas and argues that the Government could do more to narrow the scope of debate about the technology mix beyond 2020. It argues that it should work with industry and academia first to establish ‘low regrets’ levels of technology deployment and second to ensure that policies are in place to incentivise investments such as supply chain investment needed to deliver these low regrets actions.
This approach would help provide the longer term clarity that could secure supply chain investments giving the UK a head-start in the global race. The report finds that these investments could be missed delayed or more expensive if there is insufficient confidence about long term demand for key technologies such as offshore wind. Work by Government to help incentivise these investments would increase the likelihood that technology cost reductions are achieved and help mitigate against high costs if new nuclear or carbon capture and storage development fail or are delayed.
On affordability the report finds that there are ‘hidden’ benefits that the UK could see from investing more in renewables through electricity bills between now and 2020. These include: avoiding bill increases driven by fossil fuels; making electricity bills more predictable; and providing an economic boost. The extra money paid to support renewables and other low carbon generation such as nuclear power could be more than offset by energy efficiency savings although Government needs to do more to show how these savings will arise.
On sustainability the report tackles myths about the carbon emitted in manufacturing renewable technologies or in backing up varying technologies such as wind solar wave and tidal. It finds that even when considering these factors renewables are still amongst the most low carbon options. The report also looks at the sustainability of electricity from biomass. Bioenergy overall could provide up to ten per cent of energy and reduce the cost of cutting carbon by £44 billion per year in 2050. The Government’s new biomass policies are a pragmatic response to concerns about the sustainability of biomass power which balances protecting the environment building public confidence and enabling the sector to grow.
On security of supply the inquiry argues that debate should focus on the whole electricity system and that individual technologies should be considered in the context of how they add to or reduce system risks. Considered like this renewables reduce some risks such as fuel supply risks which caused concern last winter and add to others such as system balancing risks. System balancing risks from varying renewables (wind solar wave and tidal technologies) are manageable using a number of existing and developing technologies.
The independent report chaired by former Energy Minister Charles Hendry MP and Shadow Energy Minister Baroness Worthington was compiled between May and September 2013 and was sponsored by Siemens and DONG Energy. It is part of a year-long independent and cross party inquiry into the UK power sector the Future Electricity Series sponsored by the Institution of Gas Engineers and Managers.

A foresight model Future Wheels is also used to visualize the findings from the review and provide a clear picture of the potential impact of the policy.
Integrating System and Operator Perspectives for the Evaluation of Power-to-Gas Plants in the Future German Energy System
Feb 2022
Publication
In which way and in which sectors will renewable energy be integrated in the German Energy System by 2030 2040 and 2050? How can the resulting energy system be characterised following a −95% greenhouse gas emission reduction scenario? Which role will hydrogen play? To address these research questions techno-economic energy system modelling was performed. Evaluation of the resulting operation of energy technologies was carried out from a system and a business point of view. Special consideration of gas technologies such as hydrogen production transport and storage was taken as a large-scale and long-term energy storage option and key enabler for the decarbonisation of the non-electric sectors. The broad set of results gives insight into the entangled interactions of the future energy technology portfolio and its operation within a coupled energy system. Amongst other energy demands CO2 emissions hydrogen production and future power plant capacities are presented. One main conclusion is that integrating the first elements of a large-scale hydrogen infrastructure into the German energy system already by 2030 is necessary for ensuring the supply of upscaling demands across all sectors. Within the regulatory regime of 2020 it seems that this decision may come too late which jeopardises the achievement of transition targets within the horizon 2050.
Australian Hydrogen Hubs Study
Nov 2019
Publication
Arup have conducted interviews with targeted industry and government stakeholders to gather data and perspectives to support the development of this study. Arup have also utilised private and publicly available data sources building on recent work undertaken by Geoscience Australia and Deloitte and the comprehensive stakeholder engagement process to inform our research. This study considers the supply chain and infrastructure requirements to support the development of export and domestic hubs. The study aims to provide a succinct “Hydrogen Hubs” report for presentation to the hydrogen working group.
The hydrogen supply chain infrastructure required to produce hydrogen for export and domestic hubs was identified along with feedback from the stakeholder engagement process. These infrastructure requirements can be used to determine the factors for assessing export and domestic hub opportunities. Hydrogen production pathways transportation mechanisms and uses were also further evaluated to identify how hubs can be used to balance supply and demand of hydrogen.
A preliminary list of current or anticipated locations has been developed through desktop research Arup project knowledge and the stakeholder consultation process. Over 30 potential hydrogen export locations have been identified in Australia through desktop research and the stakeholder survey and consultation process. In addition to establishing export hubs the creation of domestic demand hubs will be essential to the development of an Australian hydrogen economy. It is for this reason that a list of criteria has been developed for stakeholders to consider in the siting and design of hydrogen hubs. The key considerations explored are based on demand supply chain infrastructure and investment and policy areas.
Based on these considerations a list of criteria were developed to assess the viability of export and domestic hydrogen hubs. Criteria relevant to assessing the suitability of export and domestic hubs include:
A framework that includes the assessment criteria has been developed to aid decision making rather than recommending specific locations that would be most appropriate for a hub. This is because there are so many dynamic factors that go into selecting a location of a hydrogen hub that it is not appropriate to be overly prescriptive or prevent stakeholders from selecting the best location themselves or from the market making decisions based on its own research and knowledge. The developed framework rather provides information and support to enable these decision-making processes.

Fully decarbonizing global industry is essential to achieving climate stabilization and reaching net zero greenhouse gas emissions by 2050–2070 is necessary to limit global warming to 2 °C. This paper assembles and evaluates technical and policy interventions both on the supply side and on the demand side. It identifies measures that employed together can achieve net zero industrial emissions in the required timeframe. Key supply-side technologies include energy efficiency (especially at the system level) carbon capture electrification and zero-carbon hydrogen as a heat source and chemical feedstock. There are also promising technologies specific to each of the three top-emitting industries: cement iron & steel and chemicals & plastics. These include cement admixtures and alternative chemistries several technological routes for zero-carbon steelmaking and novel chemical catalysts and separation technologies. Crucial demand-side approaches include material-efficient design reductions in material waste substituting low-carbon for high-carbon materials and circular economy interventions (such as improving product longevity reusability ease of refurbishment and recyclability). Strategic well-designed policy can accelerate innovation and provide incentives for technology deployment. High-value policies include carbon pricing with border adjustments or other price signals; robust government support for research development and deployment; and energy efficiency or emissions standards. These core policies should be supported by labeling and government procurement of low-carbon products data collection and disclosure requirements and recycling incentives. In implementing these policies care must be taken to ensure a just transition for displaced workers and affected communities. Similarly decarbonization must complement the human and economic development of low- and middle-income countries.
Hydrogen Energy Vision 2060: Hydrogen as Energy Carrier in Malaysian Primary Energy Mix – Developing P2G Case
Mar 2021
Publication
The transition of Malaysia from fossil fuels to renewable energy sources provides significant challenges and opportunities for various energy sectors. Incorporation of H2 in the primary energy mix requires a deal of complexity in its relation to production transportation and end-use. The Sarawak State Government in Malaysia implemented a hydrogen energy roadmap for the year 2005–2030 on the state-level but despite the great enthusiasm and full support given by the government the development of hydrogen technology is still far from its goals. This is due to several factors that hinder its progress including (1) inability of hydrogen to be integrated with current primary energy infrastructure (2) limited technology resources to produce sustainable hydrogen and (3) lack of technical expertise in the field of hydrogen. In this paper a potential national roadmap and milestones are presented based on the power-to-gas (P2G) approach combined with its implications on the national natural gas (NG) pipeline network. Besides that the long-term and short-term strategies and implementation mechanisms are discussed in detail. Furthermore complete research schemes are formulated to be inline with the presented vision to further enhance technology development and implementation.
Making the Hydrogen Economy Possible: Accelerating Clean Hydrogen in an Electrified Economy
Apr 2021
Publication
In its new report Making the Hydrogen Economy Possible: Accelerating clean hydrogen in an electrified economy the ETC outlines the role of clean hydrogen in achieving a highly electrified net-zero economy. The report sets out how a combination of private-sector collaboration and policy support can drive the initial ramp up of clean hydrogen production and use to reach 50 million tonnes by 2030.<br/>Clean hydrogen will play a complementary role to decarbonise sectors where direct electrification is likely to be technologically very challenging or prohibitively expensive such as in steel production and long-distance shipping. The report highlights how critical rapid ramp-up of production and use in the 2020s is to unlock cost reductions and to make mid-century growth targets achievable.<br/>This report is part of the ETC’s wider Making Mission Possible Series – a series of reports outlining how to scale up clean energy provision within the next 30 years to meet the needs of a net-zero greenhouse gas emissions (GHG) economy by mid-century. The reports in the series analyse and set out specific actions required in the next decade to put this net-zero by 2050 target within reach.
Net Zero after Covid: Behavioural Principles for Building Back Better
Dec 2020
Publication
Alongside our Sixth Carbon Budget Advice the Climate Change Committee (CCC) are publishing a paper from Professor Nick Chater the Committee’s behavioural science specialist. This paper considers three behavioural principles that explain how people have adapted so rapidly and how we might “build back better” as we emerge from the pandemic with a particular focus on meeting the challenge of dramatically reducing greenhouse gas (GHG) emissions over the coming decades. The principles are:
- The power law of practice: People organizations and whole industries learn to adapt to new ways of working following a surprisingly predictable pattern. This can help predict where adaptation to new ways of living and working is likely to succeed or fail.
- The status quo effect: People and organizations tend to prefer the current status quo but can often adjust rapidly to prefer a new status quo. However we tend to systematically underestimate such effects and therefore can sometimes resist changes that in retrospect we may ultimately prefer.
- Unwritten rules: Our social behaviour is guided by implicit guidelines about what is “appropriate” which can be somewhat independent of our personal values. Changing these implicit rules alongside changes in regulation and the law is crucial to adapting to new circumstances—and the pandemic has shown that rapid change is possible though sometimes resisted (e.g. new norms about mask wearing and social distancing).
Heat and Buildings Strategy
Oct 2021
Publication
The heat and buildings strategy sets out the government’s plan to significantly cut carbon emissions from the UK’s 30 million homes and workplaces in a simple low-cost and green way whilst ensuring this remains affordable and fair for households across the country. Like the transition to electric vehicles this will be a gradual transition which will start by incentivizing consumers and driving down costs.<br/>There are about 30 million buildings in the UK. Heating these buildings contributes to almost a quarter of all UK emissions. Addressing the carbon emissions produced in heating and powering our homes workplaces and public buildings can not only save money on energy bills and improve lives but can support up to 240000 skilled green jobs by 2035 boosting the economic recovery levelling up across the country and ensuring we build back better.<br/>The heat and buildings strategy builds on the commitments made in Clean growth: transforming heating our Energy white paper and the Prime Minister’s 10 point plan. This strategy aims to provide a clear direction of travel for the 2020s set out the strategic decisions that need to be taken this decade and demonstrate how we plan to meet our carbon targets and remain on track for net zero by 2050.
Hydrogen for a Net Zero GB An Integrated Energy Market Perspective

Our new independent report finds that hydrogen can play an important role in UK’s ambitious decarbonisation plan and boost its global industrial competitiveness.
Key insights from this new analysis include:
Key insights from this new analysis include:
- New independent report from Aurora Energy Research shows that hydrogen can meet up to half of Great Britain’s (GB) final energy demand by 2050 providing an important pathway to reaching UK’s ambitious Net Zero targets.
- The report concludes that both blue hydrogen (produced from natural gas after reforming to remove carbon content) and green hydrogen (produced by using power to electrolyse water) are expected to play an important role providing up to 480TWh of hydrogen or c.45% of GB’s final energy demand by 2050.
- All Net Zero scenarios require substantial growth in low-carbon generation such as renewables and nuclear. Large-scale hydrogen adoption could help to integrate renewables into the power system by reducing the power sector requirement for flexibility during peak winter months and boosting revenues for clean power generators by c. £3bn per year by 2050.
- The rollout of hydrogen could accelerate green growth and enable the development of globally competitive low-carbon industrial clusters while utilising UK’s competitive advantage on carbon capture.
- In facilitating the identification of a cost-effective hydrogen pathway there are some low-regret options for Government to explore including the stimulation of hydrogen demand in key sectors the deployment of CCS in strategic locations and the standardisation of networks. These initiatives could form an important part of the UK Government’s post-COVID stimulus plan.
The Green Hydrogen Puzzle: Towards a German Policy Framework for Industry
Nov 2021
Publication
Green hydrogen will play a key role in building a climate-neutral energy-intensive industry as key technologies for defossilising the production of steel and basic chemicals depend on it. Thus policy-making needs to support the creation of a market for green hydrogen and its use in industry. However it is unclear how appropriate policies should be designed and a number of challenges need to be addressed. Based on an analysis of the ongoing German debate on hydrogen policies this paper analyses how policy-making for green hydrogen development may support industry defossilisation. For the assessment of policy instruments a simplified multi-criteria analysis (MCA) is used with an innovative approach that derives criteria from specific challenges. Four challenges and seven relevant policy instruments are identified. The results of the MCA reveal the potential of each of the selected instruments to address the challenges. The paper furthermore outlines how instruments might be combined in a policy package that supports industry defossilisation creates synergies and avoids trade-offs. The paper’s impact may reach beyond the German case as the challenges are not specific to the country. The results are relevant for policy-makers in other countries with energy-intensive industries aiming to set the course towards a hydrogen future.
Life Cycle Assessment Integration into Energy System Models: An Application for Power-to-Methane in the EU
Nov 2019
Publication
As the EU energy system transitions to low carbon the technology choices should consider a broader set of criteria. The use of Life Cycle Assessment (LCA) prevents burden shift across life cycle stages or impact categories while the use of Energy System Models (ESM) allows evaluating alternative policies capacity evolution and covering all the sectors. This study does an ex-post LCA analysis of results from JRC-EU-TIMES and estimates the environmental impact indicators across 18 categories in scenarios that achieve 80–95% CO2 emission reduction by 2050. Results indicate that indirect CO2 emissions can be as large as direct ones for an 80% CO2 reduction target and up to three times as large for 95% CO2 reduction. Impact across most categories decreases by 20–40% as the CO2 emission target becomes stricter. However toxicity related impacts can become 35–100% higher. The integrated framework was also used to evaluate the Power-to-Methane (PtM) system to relate the electricity mix and various CO2 sources to the PtM environmental impact. To be more attractive than natural gas the climate change impact of the electricity used for PtM should be 123–181 gCO2eq/kWh when the CO2 comes from air or biogenic sources and 4–62 gCO2eq/kWh if the CO2 is from fossil fuels. PtM can have an impact up to 10 times larger for impact categories other than climate change. A system without PtM results in ~4% higher climate change impact and 9% higher fossil depletion while having 5–15% lower impact for most of the other categories. This is based on a scenario where 9 parameters favor PtM deployment and establishes the upper bound of the environmental impact PtM can have. Further studies should work towards integrating LCA feedback into ESM and standardizing the methodology.
The Role of Hydrogen in the Transition from a Petroleum Economy to a Low-carbon Society
Jun 2021
Publication
A radical decarbonization pathway for the Norwegian society towards 2050 is presented. The paper focuses on the role of hydrogen in the transition when present Norwegian petroleum export is gradually phased out. The study is in line with EU initiatives to secure cooperation opportunities with neighbouring countries to establish an international hydrogen market. Three analytical perspectives are combined. The first uses energy models to investigate the role of hydrogen in an energy and power market perspective without considering hydrogen export. The second uses an economic equilibrium model to examine the potential role of hydrogen export in value creation. The third analysis is a socio-technical case study on the drivers and barriers for hydrogen production in Norway. Main conclusions are that access to renewable power and hydrogen are prerequisites for decarbonization of transport and industrial sectors in Norway and that hydrogen is a key to maintain a high level of economic activity. Structural changes in the economy impacts of new technologies and key enablers and barriers in this transition are discussed.
Economic Feasibility of Green Hydrogen Production by Water Electrolysis Using Wind and Geothermal Energy Resources in Asal-Ghoubbet Rift (Republic of Djibouti): A Comparative Evaluation
Dec 2021
Publication
The Republic of Djibouti has untapped potential in terms of renewable energy resources such as geothermal wind and solar energy. This study examines the economic feasibility of green hydrogen production by water electrolysis using wind and geothermal energy resources in the Asal–Ghoubbet Rift (AG Rift) Republic of Djibouti. It is the first study in Africa that compares the cost per kg of green hydrogen produced by wind and geothermal energy from a single site. The unit cost of electricity produced by the wind turbine (0.042 $/kWh) is more competitive than that of a dry steam geothermal plant (0.086 $/kWh). The cost of producing hydrogen with a suitable electrolyzer powered by wind energy ranges from $0.672/kg H2 to $1.063/kg H2 while that produced by the high-temperature electrolyzer (HTE) powered by geothermal energy ranges from $3.31/kg H2 to $4.78/kg H2 . Thus the AG Rift area can produce electricity and green hydrogen at low-cost using wind energy compared to geothermal energy. The amount of carbon dioxide (CO2 ) emissions reduced by using a “Yinhe GX113-2.5MW” wind turbine and a single flash geothermal power plant instead of fuel-oil generators is 2061.6 tons CO2/MW/year and 2184.8 tons CO2/MW/year respectively.
The Role of Electrification and Hydrogen in Breaking the Biomass Bottleneck of the Renewable Energy System – A Study on the Danish Energy System
Jun 2020
Publication
The aim of this study is to identify the technical solution space for future fully renewable energy systems that stays within a sustainable biomass demand. In the transition towards non-fossil energy and material systems biomass is an attractive source of carbon for those demands that also in the non-fossil systems depend on high density carbon containing fuels and feedstocks. However extensive land use is already a sustainability challenge and an increase in future demands threat to exceed global sustainable biomass potentials which according to an international expert consensus is around 10 – 30 GJ/person/year in 2050. Our analytical review of 16 scenarios from 8 independent studies of fully renewable energy system designs and synthesis of 9 generic system designs reveals the significance of the role of electrification and hydrogen integration for building a fully renewable energy system which respects the global biomass limitations. The biomass demand of different fully renewable energy system designs was found to lie in the range of 0 GJ/person/year for highly integrated electrified pure electro-fuel scenarios with up to 25 GJ/person/year of hydrogen to above 200 GJ/person/year for poorly integrated full bioenergy scenarios with no electrification or hydrogen integration. It was found that a high degree of system electrification and hydrogen integration of at least 15 GJ/person/year is required to stay within sustainable biomass limits.
Hydrogen for Australia’s Future
Aug 2018
Publication
The Hydrogen Strategy Group chaired by Australia’s Chief Scientist Dr Alan Finkel has today released a briefing paper on the potential domestic and export opportunities of a hydrogen industry in Australia.
Like natural gas hydrogen can be used to heat buildings and power vehicles. Unlike natural gas or petrol when hydrogen is burned there are no CO2 emissions. The only by-products are water vapour and heat.
Hydrogen is the most abundant element in the universe not freely available as a gas on Earth but bound into many common substances including water and fossil fuels.
Hydrogen was first formally presented as a credible alternative energy source in the early 1970s but never proved competitive at scale as an energy source – until now. We find that the worldwide demand for hydrogen is set to increase substantially over coming decades driven by Japan’s decision to put imported hydrogen at the heart of its economy. Production costs are falling technologies are progressing and the push for non-nuclear low-emissions fuels is building momentum. We conclude that Australia is remarkably well-positioned to benefit from the growth of hydrogen industries and markets.

Economic Value of Flexible Hydrogen-based Polygeneration Energy Systems
Jan 2016
Publication
Polygeneration energy systems (PES) have the potential to provide a flexible high-efficiency and low-emissions alternative for power generation and chemical synthesis from fossil fuels. This study aims to assess the economic value of fossil-fuel PES which rely on hydrogen as an intermediate product. Our analysis focuses on a representative PES configuration that uses coal as the primary energy input and produces electricity and fertilizer as end-products. We derive a series of propositions that assess the cost competitiveness of the modeled PES under both static and flexible operation modes. The result is a set of metrics that quantify the levelized cost of hydrogen the unit profit-margin of PES and the real option values of ‘diversification’ and ‘flexibility’ embedded in PES. These metrics are subsequently applied to assess the economics of Hydrogen Energy California (HECA) a PES currently under development in California. Under our technical and economic assumptions HECA’s levelized cost of hydrogen is estimated at 1.373 $/kgh. The profitability of HECA as a static PES increases in the share of hydrogen converted to fertilizer rather than electricity. However when configured as a flexible PES HECA almost breaks even on a pre-tax basis. Diversification and flexibility are valuable for HECA when polygeneration is compared to static monogeneration of electricity but these two real options have no value when comparing polygeneration to static monogeneration of fertilizers.

The Role of Clean Hydrogen Value Chain in a Successful Energy Transition of Japan
Aug 2022
Publication
The clean hydrogen in the prioritized value chain platform could provide energy incentives and reduce environmental impacts. In the current study strengths weaknesses opportunities and threats (SWOT) analysis has been successfully applied to the clean hydrogen value chain in different sectors to determine Japan’s clean hydrogen value chain’s strengths weaknesses opportunities and threats as a case study. Japan was chosen as a case study since we believe that it is the only pioneer country in that chain with a national strategy investments and current projects which make it unique in this way. The analyses include evaluations of clean energy development power supply chains regional energy planning and renewable energy development including the internal and external elements that may influence the growth of the hydrogen economy in Japan. The ability of Japan to produce and use large quantities of clean hydrogen at a price that is competitive with fossil fuels is critical to the country’s future success. The implementation of an efficient carbon tax and carbon pricing is also necessary for cost parity. There will be an increasing demand for global policy coordination and inter-industry cooperation. The results obtained from this research will be a suitable model for other countries to be aware of the strengths weaknesses opportunities and threats in this field in order to make proper decisions according to their infrastructures potentials economies and socio-political states in that field.

With the emergence of hydrogen as a promising clean energy source there has been growing interest and investment in this area globally. This study investigated whether the country is likely to pursue this trend given its current energy mix and policies. A study was conducted to provide an overview of the global trends and best practices in hydrogen energy adoption and investment. The outcomes of the analysis show that the country current energy mix has the potential to produce green hydrogen energy. The evaluation of its readiness and potential obstacles for hydrogen energy adoption has been drowned and there are several challenges that need to be addressed. The study outcomes also conclude with policy implications and recommendations for the country energy industry.
The Smart Community: Strategy Layers for a New Sustainable Continental Framework
Feb 2023
Publication
The topic investigated in this article is a comparison contrast and integration effort of European strategies for sustainable development with the evolving market initiatives that are beginning to fuel the fourth industrial revolution. Several regulatory initiatives from continental bodies come into effect to radically change access to finances for business development based on sustainability goals and an analysis of the legislation and trends becomes essential for an effective pivot tactic in the face of adversity as well as change management policies to pre-emptively adapt and perform. The general research question is “what the strategic tools are best employed to overcome the hurdles laid forth by the drastic changes legally required for a sustainable future?” The research methods include a quantitative analysis of norms regulations and legislation including strategic initiatives circulated in the European Union governmental bodies integrated with qualitative research of the literature. The study finds and draws synergies between national strategies that have recently been drafted or are currently evolving with sustainability-centric initiatives such as the hydrogen initiative the nuclear initiative the natural gas initiative the renewables initiative the synthetics and biomass initiative the ESG initiative the digital initiative. The findings are to contribute to the business administration field by providing an appropriate image of the organizational design model in the sustainability era and a strategy framework to build the optimum long-term vision founded on continental regulatory initiatives that have come into effect.
Resource Assessment for Green Hydrogen Production in Kazakhstan
Jan 2023
Publication
Kazakhstan has long been regarded as a major exporter of fossil fuel energy. As the global energy sector is undergoing an unprecedented transition to low-carbon solutions new emerging energy technologies such as hydrogen production require more different resource bases than present energy technologies. Kazakhstan needs to consider whether it has enough resources to stay competitive in energy markets undergoing an energy transition. Green hydrogen can be made from water electrolysis powered by low-carbon electricity sources such as wind turbines and solar panels. We provided the first resource assessment for green hydrogen production in Kazakhstan by focusing on three essential resources: water renewable electricity and critical raw materials. Our estimations showed that with the current plan of Kazakhstan to keep its water budget constant in the future producing 2–10 Mt green hydrogen would require reducing the water use of industry in Kazakhstan by 0.6–3% or 0.036–0.18 km3/year. This could be implemented by increasing the share of renewables in electricity generation and phasing out some of the water- and carbon-intensive industries. Renewable electricity potential in South and West Kazakhstan is sufficient to run electrolyzers up to 5700 and 1600 h/year for wind turbines and solar panels respectively. In our base case scenario 5 Mt green hydrogen production would require 50 GW solar and 67 GW wind capacity considering Kazakhstan's wind and solar capacity factors. This could convert into 28652 tons of nickel 15832 tons of titanium and many other critical raw materials. Although our estimations for critical raw materials were based on limited geological data Kazakhstan has access to the most critical raw materials to support original equipment manufacturers of low-carbon technologies in Kazakhstan and other countries. As new geologic exploration kicks off in Kazakhstan it is expected that more deposits of critical raw materials will be discovered to respond to their potential future needs for green hydrogen production.
Policy Toolbox for Low Carbon and Renewable Hydrogen

Establishment of Austria’s First Regional Green Hydrogen Economy: WIVA P&G HyWest
Apr 2023
Publication
The regional parliament of Tyrol in Austria adopted the climate energy and resources strategy “Tyrol 2050 energy autonomous” in 2014 with the aim to become climate neutral and energy autonomous. “Use of own resources before others do or have to do” is the main principle within this long-term strategic approach in which the “power on demand” process is a main building block and the “power-to-hydrogen” process covers the intrinsic lack of a long-term large-scale storage of electricity. Within this long-term strategy the national research and development (R&D) flagship project WIVA P&G HyWest (ongoing since 2018) aims at the establishment of the first sustainable business-case-driven regional green hydrogen economy in central Europe. This project is mainly based on the logistic principle and is a result of synergies between three ongoing complementary implementation projects. Among these three projects to date the industrial research within “MPREIS Hydrogen” resulted in the first green hydrogen economy. One hydrogen truck is operational as of January 2023 in the region of Tyrol for food distribution and related monitoring studies have been initiated. To fulfil the logistic principle as the main outcome another two complementary projects are currently being further implemented.
Future Pathways for Energy Networks: A Review of International Experiences in High Income Countries
Oct 2022
Publication
Energy networks are the systems of pipes and wires by which different energy vectors are transported from where they are produced to where they are needed. As such these networks are central to facilitating countries’ moves away from a reliance on fossil fuels to a system based around the efficient use of renewable and other low carbon forms of energy. In this review we highlight the challenges facing energy networks from this transition in a sample of key high income countries. We identify the technical and other innovations being implemented to meet these challenges and describe some of the new policy and regulatory developments that are incentivising the required changes. We then review evidence from the literature about the benefits of moving to a more integrated approach based on the concept of a Multi-Vector Energy Network (MVEN). Under this approach the different networks are planned and operated together to achieve greater functionality and performance than simply the sum of the individual networks. We find that most studies identify a range of benefits from an MVEN approach but that these findings are based on model simulations. Further work is therefore needed to verify whether the benefits can be realised in practice and to identify how any risks can be mitigated.
Challenges of Industrial-Scale Testing Infrastructure for Green Hydrogen Technologies
Apr 2023
Publication
Green hydrogen is set to become the energy carrier of the future provided that production technologies such as electrolysis and solar water splitting can be scaled to global dimensions. Testing these hydrogen technologies on the MW scale requires the development of dedicated new test facilities for which there is no precedent. This perspective highlights the challenges to be met on the path to implementing a test facility for large-scale water electrolysis photoelectrochemical and photocatalytic water splitting and aims to serve as a much-needed blueprint for future test facilities based on the authors’ own experience in establishing the Hydrogen Lab Leuna. Key aspects to be considered are the electricity and utility requirements of the devices under testing the analysis of the produced H2 and O2 and the safety regulations for handling large quantities of H2 . Choosing the right location is crucial not only for meeting these device requirements but also for improving financial viability through supplying affordable electricity and providing a remunerated H2 sink to offset the testing costs. Due to their lower TRL and requirement for a light source large-scale photocatalysis and photoelectrochemistry testing are less developed and the requirements are currently less predictable.
Just Energy Transition: Learning from the Past for a More Just and Sustainable Hydrogen Transition in West Africa
Dec 2022
Publication
The rising demand for energy and the aim of moving away from fossil fuels and to low-carbon power have led many countries to move to alternative sources including solar energy wind geothermal energy biomass and hydrogen. Hydrogen is often considered a “missing link” in guaranteeing the energy transition providing storage and covering the volatility and intermittency of renewable energy generation. However due to potential injustice with regard to the distribution of risks benefits and costs (i.e. in regard to competing for land use) the large-scale deployment of hydrogen is a contested policy issue. This paper draws from a historical analysis of past energy projects to contribute to a more informed policy-making process toward a more just transition to the hydrogen economy. We perform a systematic literature review to identify relevant conflict factors that can influence the outcome of hydrogen energy transition projects in selected Economic Community of West African States countries namely Nigeria and Mali. To better address potential challenges policymakers must not only facilitate technology development access and market structures for hydrogen energy policies but also focus on energy access to affected communities. Further research should monitor hydrogen implementation with a special focus on societal impacts in producing countries.
