Policy & Socio-Economics

Hydrogen energy is considered one of the main measures of zero carbonization in energy systems but high equipment and hydrogen costs hinder the development of hydrogen energy technology. The objectives of this study are to quantify the environmental advantages of hydrogen energy through a carbon tax and study the application potential of hydrogen energy technology in a regional distributed energy system (RDES). In this study various building types in the smart community covered by Japan’s first hydrogen energy pipeline are used as an example. First ten buildings of five types are selected as the research objectives. Subsequently two comparative system models of a regional distributed hydrogen energy system (RDHES) and an RDES were established. Then by studying the optimal RDHES and RDES configuration and combining the prediction of future downward trends of fuel cell (FC) costs and energy carbon emissions the application effect of FC and hydrogen storage (HS) technologies on the demand side was analyzed. Finally the adaptability of the demand-side hydrogen energy system was studied by analyzing the load characteristics of different types of buildings. The results show that when the FC price is reduced to 1.5 times that of the internal combustion engine (ICE) the existing carbon tax system can sufficiently support the RDHES in gaining economic advantages in some regions. Notably when the carbon emissions of the urban energy system are reduced the RDHES demonstrates stronger anti-risk ability and has greater suitability for promotion in museums and shopping malls. The conclusions obtained in this study provide quantitative support for hydrogen energy promotion policies on the regional demand side and serve as a theoretical reference for the design and adaptability research of RDHESs.

Current technological improvements are yet to put the world on track to net-zero which will require the uptake of transformative low-carbon innovations to supplement mitigation efforts. However the role of such innovations is not yet fully understood; some of these ‘miracles’ are considered indispensable to Paris Agreement-compliant mitigation but their limitations availability and potential remain a source of debate. We evaluate such potentially game-changing innovations from the experts’ perspective aiming to support the design of realistic decarbonisation scenarios and better-informed net-zero policy strategies. In a worldwide survey 260 climate and energy experts assessed transformative innovations against their mitigation potential at-scale availability and/or widescale adoption and risk of delayed diffusion. Hierarchical clustering and multi-criteria decision-making revealed differences in perceptions of core technological innovations with next generation energy storage alternative building materials iron-ore electrolysis and hydrogen in steelmaking emerging as top priorities. Instead technologies highly represented in well-below-2◦C scenarios seemingly feature considerable and impactful delays hinting at the need to re-evaluate their role in future pathways. Experts’ assessments appear to converge more on the potential role of other disruptive innovations including lifestyle shifts and alternative economic models indicating the importance of scenarios including non-technological and demand-side innovations. To provide insights for expert elicitation processes we finally note caveats related to the level of representativeness among the 260 engaged experts the level of their expertise that may have varied across the examined innovations and the potential for subjective interpretation to which the employed linguistic scales may be prone to.

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.

Green hydrogen has become the key to social low-carbon transformation and is fully linked to zero carbon emissions. The carbon emissions trading market is a policy tool used to control carbon emissions using a market-oriented mechanism. Building a modular carbon trading center for the hydrogen energy industry would greatly promote the meeting of climate targets. Based on this a “green hydrogen market—national carbon trading market–electricity market” coupling mechanism is designed. Then the “green hydrogen market—national carbon trading market–electricity market” mechanism is modeled and simulated using system dynamics. The results are as follows: First coupling between the green hydrogen market carbon trading market and electricity market can be realized through green hydrogen certification and carbon quota trading. It is found that the coupling model is feasible through simulation. Second simulation of the basic scenario finds that multiple-market coupling can stimulate an increase in carbon price the control of thermal power generation and an increase in green hydrogen production. Finally the proportion of the green hydrogen certification the elimination mechanism of outdated units and the quota auction mechanism will help to form a carbon pricing mechanism. This study enriches the green hydrogen trading model and establishes a multiple-market linkage mechanism.

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.

Expanding decarbonization efforts beyond the power sector are contingent on cost-effective production of energy carriers like H2 with near-zero life-cycle carbon emissions. Here we assess the levelized cost of continuous H2 supply (95% availability) at industrial-scale quantities (100 tonnes/day) in 2030 from integrating commodity technologies for solar photovoltaics electrolysis and energy storage. Our approach relies on modeling the least-cost plant design and operation that optimize component sizes while adhering to hourly solar availability production requirements and component inter-temporal operating constraints. We apply the model to study H2 production costs spanning the continental United States and through extensive sensitivity analysis explore system configurations that can achieve $2.5/kg levelized costs or less for a range of plausible 2030 technology projections at high-irradiance locations. Notably we identify potential sites and system configurations where PV-electrolytic H2 could substitute natural gas-derived H2 at avoided CO2 costs (%$120/ton) similar to the cost of deploying carbon capture and sequestration.

The liquid hydrogen demand particularly driven by clean energy applications will rise in the near future. As industrial large scale liquefiers will play a major role within the hydrogen supply chain production capacity will have to increase by a multiple of today’s typical sizes. The main goal is to reduce the total cost of ownership for these plants by increasing energy efficiency with innovative and simple process designs optimized in capital expenditure. New concepts must ensure a manageable plant complexity and flexible operability. In the phase of process development and selection a dimensioning of key equipment for large scale liquefiers such as turbines and compressors as well as heat exchangers must be performed iteratively to ensure technological feasibility and maturity. Further critical aspects related to hydrogen liquefaction e.g. fluid properties ortho-para hydrogen conversion and coldbox configuration must be analysed in detail. This paper provides an overview on the approach challenges and preliminary results in the development of efficient as well as economically viable concepts for large-scale hydrogen liquefaction.

The combination of offshore wind and green hydrogen provides major opportunities for job creation economic growth and regional regeneration as well as attracting inward investment alongside delivering the emission reductions needed to achieve climate neutrality. In order to get to Net Zero emissions in 2050 the UK is likely to need a minimum of 75GW of offshore wind (OSW) and modelling of the energy system indicates that hydrogen will play a major role in integrating the high levels of OSW on the electricity grid.<br/><br/>Some of the key findings from report are listed below:<br/><br/>The UK has vast resources of offshore wind with the potential for over 600GW in UK waters and potentially up to 1000GW. This is well above the he figure of 75-100GW likely to be needed for UK electricity generation by 2050.<br/>The universities in the UK provide the underpinning science and engineering for electrolysers fuel cells and hydrogen and are home to world-leading capability in these areas.<br/>In order to achieve cost reduction and growing a significant manufacturing and export industry it will be crucial to develop green hydrogen in the next 5 years<br/>By 2050 green hydrogen can be cheaper than blue hydrogen. With accelerated deployment green hydrogen costs can be competitive with blue hydrogen by the eary 2030s.<br/>The combination of additional OSW deployment and electrolyser manufacture alone could generate over 120000 new jobs. These are are expected to be based mainly in manufacturing OSW-related activity shipping and mobility<br/>By 2050 it is estimated that the cumulative gross value added (GVA) from supply of electrolysers and additional OSW farm could be up to £320bn where the majority will come from exports of electrolysers to overseas markets.<br/>The report also calls for immediate government intervention and a new national strategy to support the creation of supply and demand in the new industry.<br/><br/>This study was jointly supported by the Offshore Wind Industry Council (OWIC) and ORE Catapult.

ISSUES MONITOR 2020: DECODING NEW SIGNALS OF CHANGE

The annual World Energy Issues Monitor provides unique insight into what energy policymakers CEOs and leading experts identify as Critical Uncertainties and Action Priorities. New this year the Issues Monitor also provides readers with the views of the individual customer detailing their perceptions of their role in the overall energy system. The Issues Monitor report includes a global issues map 58 country maps and six regional maps as well as perspectives from Future Energy Leaders (FEL) and energy innovators.

GLOBAL PERSPECTIVES

The 2020 global map incorporates all survey responses representing the views of over 3000 energy leaders from 104 countries. In this era of transition defined by decentralisation digitalisation and decarbonisation energy leaders must pay attention to many different signals of change and distinguish key issues from the noise. The Issues Monitor identifies shifting patterns of connected issues shaping energy transitions.

A NEW PULSE

The focus for the 2010s was about trying to automate and upgrade the energy system and set targets to move the energy transition forward. Digitalisation accelerated the transition of all sectors towards a more customer-centric environment. New policies and regulations were introduced to facilitate this transition and empower consumers. As a result the 2020s may very well be about realising those targets through a transition from activism to action.

TREND TRACKING: CCS

In comparing response from the Oil & Gas sector in 2015 with 2019 we found that almost half of respondents identified Carbon Capture & Storage (CCS) as a high impact issue in 2019 up from about a third in 2015. CCS is increasingly being viewed as an essential option for continued hydrocarbon use although governmental support is needed to enable scalability and cost effectiveness.

A DIFFERENCE IN OPINION: NUCLEAR

Opinions remain polarised but in many European countries nuclear power is increasingly recognised as a carbon-free energy source and potentially an integral part of the future energy mix. In December 2019 the European Commission set a target of net-zero carbon emissions by 2050. There is qualified support among energy leaders to include nuclear energy to help create a carbon neutral continent and enable a just energy transition.

Study setting out a vision and plan for a multi-modal hydrogen transport hub within the UK. The study considers the:

• size of operational trials
• quantity of green hydrogen required
• research and development facilities which will support a living lab
• green hydrogen infrastructure required including:
• production
• storage
• distribution
• The study uses Tees Valley as an example region although the blueprint may be applied to other areas.

This report was independently produced on behalf of the Department for Transport by Mott Macdonald.

The Energy Research Accelerator (ERA) and the Birmingham Energy Institute have launched a policy commission to examine the state of play barriers challenges and opportunities for Energy from Waste (EfW) to form part of the regional energy circular economy in the Midlands. This policy commission explores the case for regional investment whilst helping shape the regional local government and industry thinking surrounding critical issues such as fuel poverty and poor air quality.

The Challenge

Tackling climate change is one of the most pressing issues of our time. To follow the path for limiting global warming below 2^ᵒC set out in the 2015 Paris agreement requires significant reduction in greenhouse gas emissions. The UK has committed to bring all greenhouse gas emissions to net zero by 2050 requiring action at a local regional and national level to transition to a zero carbon economy.

To decarbonise and decentralise the UK’s energy system we must implement technologies that provide energy supply solutions across the UK.

In the Midlands many industrial sites are unable to access supply of affordable clean and reliable energy to meet their demands.

Energy from Waste (EfW) could offer a solution to the Midlands based industrial sites. EfW sites provide affordable secure energy supply solutions that form part of a developing circular economy. EfW reduces our reliance on landfills and obtains the maximum value from our waste streams. There are a number of merging technologies that could potentially play an important role which treats waste as a resource properly integrated into an energy and transport system and fully respects the potential of linking in the circular economy.

Investment into EfW infrastructure in the region could lead to job creation and economic growth and could help provide inward investment needed to redevelop old industrial sites and retiring power stations. However for EfW to be part of a net-zero energy system (either in transition or long-term) technologies and processes are needed that reduce the current carbon emissions burden.

EfW could play a significant role in the net zero carbon transition in the Midlands supplying heat power and green fuels and solve other problems - the region has some of the highest levels of energy/fuel poverty and poor air quality in the UK.  The policy commission will help shape the regional local government and industry thinking surrounding this important topic.

Report Recommendations

Recovery Resource Cluster

The EfW policy commission proposes three major areas where it believes that government investment would be highly beneficial

• Building a network of local and regional Resource Recovery Clusters
• Creating a National Centre for the Circular Economy
• Launching an R&D Grand Challenge to develop small-scale circular carbon capture technologies.

The Resource Recovery Clusters (RRC) will be developed on post-industrial sites which could produce significant environmental economic and regeneration benefits. The RRCs combine a spread of EfW and recycling technologies with businesses that can consume their cheap electricity heat fuels CO₂ and material outputs.

The National Centre for the Circular Economy would analyse material flows throughout the economy down to regional and local levels and develop deep expertise in recycling and EfW technologies. The CCE would also provide expert guidance and support for local authorities as they develop local or regional strategies and planning frameworks.

The R&D Grand Challenge aims to make big advances in small-scale carbon capture technologies in order to turn 100% of CO₂ produced through the process of converting waste to energy into useful products. This is very important for areas such as the Midlands which are remoted from depleted oil and gas reservoirs.

This White Paper has been commissioned by the UK Hydrogen and Fuel Cell (H2FC) SUPERGEN Hub to examine the roles and potential benefits of hydrogen and fuel cell technologies for heat provision in future low-carbon energy systems. The H2FC SUPERGEN Hub is an inclusive network encompassing the entire UK hydrogen and fuel cells research community with around 100 UK-based academics supported by key stakeholders from industry and government. It is funded by the UK EPSRC research council as part of the RCUK Energy Programme. This paper is the first of four that will be published over the lifetime of the Hub with the others examining: (i) low-carbon energy systems (including balancing renewable intermittency); (ii) low-carbon transport systems; and (iii) the provision of secure and affordable energy supplies for the future

• Hydrogen and fuel cells are part of the cost-optimal heating technology portfolio in long-term UK energy system scenarios.
• Fuel cell CHP is already being deployed commercially around the world.
• Hydrogen can be a zero-carbon alternative to natural gas. Most technologies that use natural gas can be adapted to use hydrogen and still provide the same level of service.
• Hydrogen and fuel cell technologies avoid some of the disadvantages of other low-carbon heating technologies.

Scaling up renewables to meet the 1.5ºC climate goal

As global economies aim to become carbon neutral competitive hydrogen produced with renewables has emerged as a key component of the energy mix. Falling renewable power costs and improving electrolyser technologies could make ""green"" hydrogen cost competitive by 2030 this report finds.

Green hydrogen can help to achieve net-zero carbon dioxide (CO₂) emissions in energy-intensive hard-to-decarbonise sectors like steel chemicals long-haul transport shipping and aviation. But production costs must be cut to make it economical for countries worldwide. Green hydrogen currently costs between two and three times more than ""blue"" hydrogen which is produced using fossil fuels in combination with carbon capture and storage (CCS).

This report from the International Renewable Energy Agency (IRENA) outlines strategies to reduce electrolyser costs through continuous innovation performance improvements and upscaling from megawatt (MW) to multi-gigawatt (GW) levels.

Among the findings:

• Electrolyser design and construction: Increased module size and innovation with increased stack manufacturing have significant impacts on cost. Increasing plant size from 1 MW (typical in 2020) to 20 MW could reduce costs by over a third. Optimal system designs maximise efficiency and flexibility.
• Economies of scale: Increasing stack production with automated processes in gigawatt-scale manufacturing facilities can achieve a step-change cost reduction. Procurement of materials: Scarcity of materials can impede electrolyser cost reduction and scale-up.
• Efficiency and flexibility in operations: Power supply incurs large efficiency losses at low load limiting system flexibility from an economic perspective.
• Industrial applications: Design and operation of electrolysis systems can be optimised for specific applications in different industries. Learning rates: Based on historic cost declines for solar photovoltaics (PV) the learning rates for fuel cells and electrolysers – whereby costs fall as capacity expands – could reach values between 16% and 21%.
• Ambitious climate mitigation: An ambitious energy transition aligned with key international climate goals would drive rapid cost reduction for green hydrogen. The trajectory needed to limit global warming at 1.5oC could make electrolysers an estimated 40% cheaper by 2030.

As the UK’s largest emitter of greenhouse gases the supply of domestic industrial and commercial heat must be decarbonised if the UK is to meet its climate change targets.<br/><br/>This report publishes the outcomes from Phase 1 of the Energy Technologies Institute’s Smart Systems and Heat programme highlighting that for the UK to transition to a low carbon heating system it must understand consumer needs and behaviours while connecting this with the development and integration of technologies and new business models.<br/><br/>Written by the ETI with support from the Energy Systems Catapult this report tackles three interconnected areas: heating needs and controls within the home; heating infrastructure and building retrofit at a local level; and the operation and governance of the whole system.<br/><br/>The research also shows that as part of a low carbon heating system upgrade advanced controls are critical to performance sizing and operating costs enabling smaller appliances and lower peak electricity demands and maximising the efficiency of existing infrastructure. With significant fabric retrofits potentially required in around 10 million of the existing 28 million dwellings in the UK housing stock the report recommends that building new homes to be both very efficient and “low carbon ready” is a low regret decision which should be progressed with some urgency.

Achieving the UK's net zero target by 2050 will be a challenge. Hydrogen can make a substantial contribution but it needs investment and policy support to establish demand increase the scale of deployment and reduce costs. The Ten Point Plan for a Green Industrial Revolution confirms the government’s commitment to drive the growth of low carbon hydrogen in the UK through a range of measures. This includes publishing its hydrogen strategy and setting out revenue mechanisms to attract private investment as well as allocating further support for hydrogen production and hydrogen applications in heating.

We have created a bespoke model to help understand the cost of hydrogen in the UK across the value chain under different pathways. Our analysis highlights areas for cost reduction and identifies factors that could make hydrogen more attractive to investors.

Based on data collection carried out between October and December 2020 and the testing of emerging findings with the Council’s regional communities during a series of digital workshops held during February 2021 the report has shown

• Energy leaders’ perceptions of areas of risk opportunity and priorities for action have radically changed over the last 12 months. While economic turbulence stemming from the ongoing reverberations of COVID-19 is the biggest area of uncertainty with uncertainty around economic trends increasing by a third over the previous year there is also a growing focus on the social agenda associated with a faster paced energy transition.

 

• There is an increased awareness of the societal and human impact of both recovery and the wider energy transition. The issue of energy affordability has rapidly risen up the industry’s priority list with its impact and uncertainty perceived 20% larger than a year ago. Energy affordability affects society across all geographies ranging from city dwellers in developed countries to the rural poor in developing ones.

 

• The emergence of a new generation of digital energy services and energy entrepreneurs. Increasingly agile disruptive technologies have taken advantage of the social upheaval to gain market share at the expense of supply-centric energy solutions. There is a growing focus on customer-centric demand-driven solutions and fast changing patterns of global and local demand.

The Hydrogen Taskforce welcomes the opportunity to submit evidence to the Environmental Audit Committee’s inquiry into Hydrogen. It is the Taskforce’s view that:

• Due to its various applications hydrogen is critical for the UK to reach net zero by 2050;
• The UK holds world-class advantages in hydrogen production distribution and application; and
• Other economies are moving ahead in the development of this sector and the UK must respond.

The Taskforce has defined a set of policy recommendations for Government which are designed to ensure that hydrogen can scale to meet the future demands of a net zero energy system:

• Development of a cross departmental UK Hydrogen Strategy within UK Government;
• Commit £1bn of capex funding over the next spending review period to hydrogen production storage and distribution projects;
• Develop a financial support scheme for the production of hydrogen in blending industry power and transport;
• Amend Gas Safety Management Regulations (GSMR) to enable hydrogen blending and take the next steps towards 100% hydrogen heating through supporting public trials and mandating 100% hydrogen-ready boilers by 2025; and
• Commit to the support of 100 Hydrogen Refuelling Stations (HRS) by 2025 to support the roll-out of hydrogen transport.

As the world strives to cut carbon emissions electric power from renewables has emerged as a vital energy source. Yet transport and industry will still require combustible fuels for many purposes. Such needs could be met with hydrogen which itself can be produced using renewable power.



Hydrogen provides high-grade heat helping to meet a range of energy needs that would be difficult to address through direct electrification. This could make hydrogen the missing link in the transformation of the global energy system.  



Key sectors for renewable-based hydrogen uptake include:  

• Industry where it could replace fossil-based feedstocks including natural gas in high-emission applications.
• Buildings and power where it could be mixed with natural gas or combined with industrial carbon dioxide (CO2) emissions to produce syngas.
• Transport where it can provide low-carbon mobility through fuel-cell electric vehicles.  

Electrolysers – which split hydrogen and oxygen – can make power systems more flexible helping to integrate high shares of variable renewables. Power consumption for electrolysis can be adjusted to follow actual solar and wind output while producing the hydrogen needed for transport industry or injection into the gas grid.  



In the long run hydrogen could become a key element in 100% renewable energy systems. With technologies maturing actual scale-up should yield major cost reductions. The right policy and regulatory framework however remains crucial to stimulate private investment in in hydrogen production in the first place.

A method of risk identification is developed by comparing existing and advanced technologies from the viewpoint of comprehensive social risk. First to analyze these values from a multifaceted perspective we constructed a questionnaire based on 24 individual values and 26 infrastructural values determined in a previous study. Seven engineering experts and six social science experts were then asked to complete the questionnaire to compare and analyze a hydrogen energy system (HES) and a gasoline energy system (GES). Finally the responses were weighted using the analytic hierarchy process. Three important points were identified and focused upon: the distinct disadvantages of the HES compared to the GES judgments that were divided between experts in the engineering and social sciences fields and judgments that were divided among experts in the same field. These are important risks that should be evaluated when making decisions related to the implementation of advanced science and technology.

<br/>The decarbonisation of heating represents a transformative challenge for many countries. The UK’s net-zero greenhouse gas emissions target requires the removal of fossil fuel combustion from heating in just three decades. A greater understanding of policy processes linked to system transformations is expected to be of value for understanding systemic change; how policy makers perceive policy issues can impact on policy change with knock-on effects for energy system change. This article builds on the literature considering policy maker perceptions and focuses on the issue of UK heat policy. Using qualitative analysis we show that policy makers perceive heat decarbonisation as disruptive technological pathways are seen as deeply uncertain and heat decarbonisation appears to offer policy makers little ‘up-side’. Perceptions are bounded by uncertainty affected by concerns over negative impacts influenced by external influences and relate to ideas of continuity. Further research and evidence on optimal heat decarbonisation and an adaptive approach to governance could support policy makers to deliver policy commensurate with heat decarbonisation. However even with reduced uncertainty and more flexible governance the perceptions of disruption to consumers mean that transformative heat policy may remain unpopular for policy makers potentially putting greenhouse mitigation targets at risk of being missed.

This week on the show the team take a pause to review the current state of hydrogen and fuel cell affairs globally whilst taking time to go over all the excellent questions that our listeners have kindly shared with us over the last few months.

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.

This week on the show the team catch up with Alena Fargere Principal at SWEN Capital Partners and a former special advisor to the World Energy Council on Hydrogen projects. As one of the few current project finance funds in Europe with a green gas mandate and a dedicated allocation for investing in hydrogen project finance SWEN Capital Partners provide an invaluable perspective on the challenges and opportunities for hydrogen project investment in Europe and the synergies that exist from Green Gas funds that support biogas and hydrogen opportunities. On the show our hosts discuss the rationale for this fund the profile of projects SWEN are considering and Alena’s broader perspective on the hydrogen market. All this and many more themes this week so don’t miss this episode!

This article attempts to model interdependencies between socio-economic energy and environmental factors with selected data characterizing the development of the hydrogen economy. The study applies Spearman’s correlation and a linear regression model to estimate the influence of gross domestic product population final energy consumption renewable energy and CO2 emission on chosen hydrogen indicators—production patents energy technology research development and demonstration budgets. The study was conducted in nine countries selected for their actions towards a hydrogen economy based on analyses of national strategies policies research and development programs and roadmaps. The results confirm the statistically significant impact of the chosen indicators which are the drivers for the development of the hydrogen economy from 2008 to 2018. Moreover the empirical results show that different characteristics in each country contribute to the development of the hydrogen economy vision

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.

On the season premier episode the EAH hosts are joined by the Governor of New Mexico Michelle Lujan Grisham. The State of New Mexico has the opportunity to lead the United States into the hydrogen era and the Governor and her team are poised to take the opportunity to make New Mexico the strategic center of the US hydrogen economy. The Governor is joined by New Mexico Environment Department Secretary James Kenney on the show to announce the forthcoming New Mexico Hydrogen Hub Act which her administration expects to drive investment in the state job growth in the energy sector and catapult New Mexico to top of the list of states driving the hydrogen revolution.

On this weeks episode the team are talking all things hydrogen with Lorna Millington Future Networks Manager in the Safety and Network Strategy team at Cadent. On the show we discuss the role that Cadent and other gas distribution network operators (GDNOs) are playing in supporting the transition towards a low (and eventually zero) carbon gas grid through the use of hydrogen. The potential for hydrogen to support decarbonisation of heat through the gas network is one of the most exciting emerging themes for countries that have large existing gas networks and who are looking to repurpose those assets towards national net zero objectives. As a leader on hydrogen into the gas grid projects Cadent offer a wealth of knowledge around the potential opportunities and considerations for displacing natural gas with hydrogen over time. And given the chance to reduce up to 6 million tonnes of CO2 a year through using more hydrogen in the gas grid this is a show you won’t want to miss! All this and more on the show!

This independent cross-party report highlights the key role that political consensus can play in helping to reduce the costs of nuclear power in the UK as well as other low carbon technologies. This political consensus has never been more important than in this ‘defining decade’ for the power sector. The report highlights that an immediate challenge facing the UK’s new build programme is agreeing with the European Commission a regime for supporting new nuclear power. Changing the proposed support package would not be an impossible task if made necessary but maintaining broad political consensus and considering the implications of delay are also important. The State Aid process is an important opportunity for scrutiny with the report demonstrating that shareholders for Hinkley Point C could see bigger returns (19-21%) than those typically expected for PFI projects (12-15%). However it is too early to conclude on the value for money of the Hinkley Point C agreement. Both the negotiation process and the resulting investment contract are important but there has been little transparency over either so far and the negotiations were not competitive. The inquiry calls for more urgency and better coordination in seizing the opportunity to reuse the UK’s plutonium stockpile.



The UK’s stockpile of separated plutonium presents opportunities to tackle a number of national strategic priorities including implementing long term solutions for nuclear waste developing new technologies that could redefine the sector laying the ground for new nuclear power and pursuing nuclear non-proliferation.  Government has identified three ‘credible solutions’ for reuse and the report recommends that it now sets clearer criteria against which to assess options and identifies budgetary requirements to help expediate the process. The report also argues that Government should do more on new nuclear technologies that could redefine the sector – such as considering smaller reactors nuclear for industrial heat or hydrogen production and closed or thorium fuel cycles. The Government’s initial response to a review of nuclear R&D a year ago by the then Chief Scientific Advisor Sir John Beddington has been welcome and it needs to build on this. In particular the UK should capitalise upon its existing expertise and past experience to focus efforts where there is most strategic value. Nulcear waste. Having failed to date the Government must urgently revisit plans for finding a site to store nuclear waste underground for thousands of years. Implementing this is a crucial part of demonstrating that nuclear waste is a manageable challenge. Despite being rejected by Cumbria County Council the continuing strong support amongst communities in West Cumbria for hosting a site is a promising sign.



On affordability the report finds that it is not yet clear which electricity generation technologies will be cheapest in the 2020s and beyond. Coal and gas could get more expensive if fossil fuel and carbon prices rise whilst low carbon technologies could get cheaper as technology costs fall with more deployment. This is the main reason for adopting an ‘all of the above’ strategy including nuclear power until costs become clearer and there is broad consensus behind this general approach.  



On security of supply the inquiry says that deployment of nuclear power is likely to be influenced more by the economics of system balancing rather than technical system balancing challenges which can be met with greater deployment of existing balancing tools. The cost of maintaining system security is likely to mean that the UK maintains at least some baseload capacity such as nuclear power to limit system costs.



On sustainability the report finds that the environmental impacts of nuclear power are comparable to some generation technologies and favourable to others although the long lived nature of some radioactive nuclear waste and the dual use potential of nuclear technology for civil and military applications create unique sustainability challenges which the UK is a world leader in managing.



It is the final report of the Future Electricity Series an independent and cross party inquiry into the UK power sector sponsored by the Institution of Gas Engineers and Managers

Hydrogen which is expected to be a popular type of next-generation energy is drawing attention as a fuel option for the formation of a low-carbon society. Because hydrogen energy is different in nature from existing energy technologies it is necessary to promote sufficient social recognition and acceptability of the technology for its widespread use. In this study we focused on the effect of initiatives to improve awareness of hydrogen energy technology thereby investigating the acceptability of hydrogen energy to those participating in either several hydrogen energy technology introduction events or professional seminars. According to the survey results participants in the technology introduction events tended to have lower levels of hydrogen and hydrogen energy technology knowledge than did participants in the hydrogen-energy-related seminars but confidence in the technology and acceptability of the installation of hydrogen stations near their own residences tended to be higher. It was suggested that knowledge about hydrogen and technology could lead to improved acceptability through improved levels of trust in the technology. On the other hand social benefits such as those for the environment socioeconomics and energy security have little impact on individual levels of acceptance of new technology.

The report was formally launched on 2nd December in Parliament at a panel debate chaired by Lord Whitty and Oliver Colvile and featured representatives from Government and Industry. The report outlines the case for investment by businesses in the energy efficiency of their buildings and operations and highlights how this could help neutralise the threat to profitability posed by increasing energy bills energy price volatility and an increasing reliance on electricity in the commercial sector. The report highlights that business in the UK have the opportunity to not only reduce energy bills but increase their competitiveness and improve worker productivity through better designed buildings.

The Czech Republic’s Hydrogen Strategy is being developed in the context of the Hydrogen Strategy for a climate neutral Europe which reflects the European Green Deal objective of climate neutrality by 2050. The objective of the Strategy is thus to reduce greenhouse gas emissions in such a way that the economy shifts smoothly to low-carbon technologies.

This is associated with two strategic goals:

• Reduce greenhouse gas emissions
• Stimulate the economic growth

To achieve these four specific goals have been set:

• Volume of low-carbon hydrogen production
• Volume of low-carbon hydrogen consumption
• Infrastructure readiness for hydrogen transport and storage
• Progress in R&D and production of hydrogen technologies

The Hydrogen Strategy is based on four pillars:

• Low-carbon hydrogen production
• Low-carbon hydrogen use
• Hydrogen transport and storage
• Hydrogen technologies

These pillars are interlinked – production and consumption must be well-balanced to achieve economic use of the respective technologies otherwise any imbalance will be offset by imports from abroad. Each of the pillars is linked to exactly one strategic goal.

Policy for Heat: Transforming the System urges Government to implement an ambitious long-term decarbonisation strategy for the heat sector before it’s too late in new inquiry report. The report builds on the work of Part 1 in the Future Heat Series which compared recent decarbonisation pathways and analyses to identify and highlight key policy mechanisms and transitions that are needed in order to decarbonise heat for buildings by 2050. Chaired by Shadow Energy Minister Jonathan Reynolds MP and Conservative MP Rebecca Pow (and also previous MP and member of the Energy and Climate Change Select Committee Dan Byles MP until he stood down at the General Election) the report is written by cross-party think tank group Carbon Connect. The report was published in Parliament at a cross-party debate on Wednesday 14th October. Sponsored by Energy & Utilities Alliance (EUA) and the Institution of Gas Engineers and Managers (IGEM) the report is the second in a cross-party and independent inquiry series.

This article aims to present the potential of energy transition in insular systems for social and economic transition and development when planned and implemented appropriately with the active involvement of local communities. To this end the example of Sifnos Energy Community is examined and presented as a pilot case. It proves that energy transition apart from its obvious energy conservation and climate necessity can provide a strong contribution to the development of remote areas and the remedying of crucial issues especially in insular communities such as unemployment low standards of living isolation and energy supply security. Energy transition on Sifnos has been undertaken by the Sifnos Energy Community (SEC) with the target to achieve 100% energy independency through effective and rational projects. The major project is a centralized hybrid power plant consisting of a wind park and a pumped hydro storage system. It was designed to fully cover the current electricity demand and the anticipated forthcoming load due to the overall transition to e-mobility for the transportation sector on the island. Through the exploitation of the excess electricity production with the production of potable water and hydrogen energy transition can facilitate the development of new professional activities on the island and reduce the local economy’s dependence on tourism. Additionally a daily link to the neighboring larger Cyclades islands can be established with a hydrogen powered-passenger vessel ensuring the secure and cheap overseas transportation connection of Sifnos throughout the whole year. The overall energy transition process is executed with the active involvement of the Sifnos citizens ensuring wide public acceptance and the minimization of the projects’ impacts on the natural and human environment. At the same time the anticipated benefits for the insular communities are maximized highlighting the energy transition process on Sifnos as a new sustainable development pattern. For all this effort and the already achieved results Sifnos has been declared as one of the six pilot islands of the European Community’s initiative “Clean Energy for EU Islands”.

Hydrogen will become a key player in transitioning toward a net-zero energy system. However a clear pathway toward a unified European hydrogen infrastructure to support the rapid scale-up of hydrogen production is still under discussion. This study explores plausible pathways using a fully sector-coupled energy system model. Here we assess the emergence of hydrogen infrastructure build-outs connecting neighboring European nations through hydrogen import and domestic production centers with Western and Central European demands via four distinct hydrogen corridors. We identify a potential lock-in effect of blue hydrogen in the medium term highlighting the risk of longterm dependence on methane. In contrast we show that a self-sufficient Europe relying on domestic green hydrogen by 2050 would increase yearly expenses by around 3% and require 518 gigawatts of electrolysis capacity. This study emphasizes the importance of rapidly scaling up electrolysis capacity building hydrogen networks and storage facilities deploying renewable electricity generation and ensuring coherent coordination across European nations.

Many energy system optimization studies show that hydrogen may be an important part of an optimal decarbonisation mix but such analyses are unable to examine the uncertainties associated with breaking the ‘locked-in’ nature of incumbent systems. Uncertainties around technical learning rates; consumer behaviour; and the strategic interactions of governments automakers and fuel providers are particularly acute. System dynamics and agent-based models and studies of historical alternative fuel transitions have furthered our understanding of possible transition dynamics but these types of analysis exclude broader systemic issues concerning energy system evolution (e.g. supplies and prices of low-carbon energy) and the politics of transitions. This paper presents a hybrid approach to assessing hydrogen transitions in the UK by linking qualitative scenarios with quantitative energy systems modelling using the UK MARKAL model. Three possible transition pathways are explored each exploring different uncertainties and possible decision points with modelling used to inform and test key elements of each scenario. The scenarios draw on literature review and participatory input and the scenario structure is based on archetypal transition dynamics drawn from historical energy system transitions reflecting insights relating to innovation system development and resistance to change. Conclusions are drawn about appropriate policy responses.

The following report is a research piece outlining the potential pathways for decarbonisation of Scottish Industries. Two main pathways are considered hydrogen and electrification with both resulting in similar costs and levels of carbon reduction.

Initial assessment of Scotland’s opportunity to produce green hydrogen from offshore wind

Summary of Key Findings

• Scotland has an abundant offshore wind resource that has the potential to be a vital component in our net zero transition. If used to produce green hydrogen offshore wind can help abate the emissions of historically challenging sectors such as heating transport and industry.
• The production of green hydrogen from offshore wind can help overcome Scotland’s grid constraints and unlock a massive clean power generation resource creating a clean fuel for Scottish industry and households and a highly valuable commodity to supply rapidly growing UK and European markets.
• The primary export markets for Scottish green hydrogen are expected to be in Northern Europe (Germany Netherlands & Belgium). Strong competition to supply these markets is expected to come from green hydrogen produced from solar energy in Southern Europe and North Africa.
• Falling wind and electrolyser costs will enable green hydrogen production to be cost-competitive in the key transport and heat sectors by 2032. Strategic investment in hydrogen transportation and storage is essential to unlocking the economic opportunity for Scotland.
• Xodus’ analysis supports a long-term outlook of LCoH falling towards £2/kg with an estimated reference cost of £2.3 /kg in 2032 for hydrogen delivered to shore.
• Scotland has extensive port and pipeline infrastructure that can be repurposed for hydrogen export to the rest of UK and to Europe. Pipelines from the ‘90s are optimal for this purpose as they are likely to retain acceptable mechanical integrity and have a metallurgy better suited to hydrogen service. A more detailed assessment of export options should be performed to provide a firm foundation for early commercial green hydrogen projects.
• There is considerable hydrogen supply chain overlap with elements of parallel sectors most notably the oil and gas offshore wind and subsea engineering sectors. Scotland already has a mature hydrocarbon supply chain which is engaged in supporting green hydrogen. However a steady pipeline of early projects supported by a clear financeable route to market will be needed to secure this supply chain capability through to widescale commercial deployment.
• There are gaps in the Scottish supply chain in the areas of design manufacture and maintenance of hydrogen production storage and transportation systems. Support including apprenticeships will be needed to develop indigenous skills and capabilities in these areas.
• The development of green hydrogen from offshore wind has the potential to create high value jobs a significant proportion which are likely to be in remote rural/coastal communities located close to offshore wind resources. These can serve as an avenue for workers to redeploy and develop skills learned from oil and gas in line with Just Transition principles.

The World Energy Transitions Outlook preview outlines a pathway for the world to achieve the Paris Agreement goals and halt the pace of climate change by transforming the global energy landscape. This preview presents options to limit global temperature rise to 1.5°C and bring CO₂ emissions closer to net zero by mid-century offering high-level insights on technology choices investment needs and the socio-economic contexts of achieving a sustainable resilient and inclusive energy future.



Meeting CO₂ reduction targets by 2050 will require a combination of: technology and innovation to advance the energy transition and improve carbon management; supportive and proactive policies; associated job creation and socio-economic improvements; and international co-operation to guarantee energy availability and access.



Among key findings:

• Proven technologies for a net-zero energy system already largely exist today. Renewable power green hydrogen and modern bioenergy will dominate the world of energy of the future.
• A combination of technologies is needed to keep us on a 1.5°C climate pathway. These include increasingly efficient energy production to ensure economic growth; decarbonised power systems that are dominated by renewables; increased use of electricity in buildings industry and transport to support decarbonisation; expanded production and use of green hydrogen synthetic fuels and feedstocks; and targeted use of sustainably sourced biomass.
• In anticipation of the coming energy transition financial markets and investors are already directing capital away from fossil fuels and towards other energy technologies including renewables.
• Energy transition investment will have to increase by 30% over planned investment to a total of USD 131 trillion between now and 2050 corresponding to USD 4.4 trillion on average every year.
• National social and economic policies will play fundamental roles in delivering the energy transition at the speed required to restrict global warming to 1.5°C.

This preview identifies opportunities to support informed policy and decision making to establish a new global energy system. Following this preview and aligned with the UN High-Level Dialogue process the International Renewable Energy Agency (IRENA) will release the full report which will provide a comprehensive vision and accompanying policy measures for the transition.

The Energy Technologies Institute (ETI) has developed an internationally peer-reviewed model of the UK’s national energy system extending across power heat transport and infrastructure. The Energy System Modelling Environment (ESME) is a policy neutral system-wide optimisation model. It models the key technology and engineering choices taking account of cost engineering spatial and temporal factors.

Key points:

• A system-wide perspective informed by modelling is highly relevant because complex energy systems are made more inter-dependent by emissions reduction objectives
• Efforts to cut emissions are substitutable across a national energy system encompassing power heat transport and infrastructure.
• Energy systems are subject to key decision points and it is important to make the right choices in major long lived investments
• Policy makers should place policy in a system-wide context.

The ETI’s current ESME-based analysis of the UK energy system shows that

• Decarbonisation can be achieved affordably (at around 0.6% of GDP) provided that the most cost effective technologies and strategies to reduce emissions are deployed
• A broad portfolio of technologies is needed to deliver emissions reductions with bio-energy and carbon capture and storage of particular system-wide importance

Policy makers can use energy system modelling to inform market and policy design increase understanding of pathways (including the impacts of ‘real world’ constraints and inertia in deploying technology) and identify key ‘contender’ technologies with particular system-wide value.

Outline

This is the eighth annual Progress Report to the Scottish Parliament required by Scottish Ministers under the Climate Change (Scotland) Act 2009. It assesses Scotland’s progress in achieving its legislated targets to reduce greenhouse gas emissions

Overall greenhouse gas emissions reduced by 3% in 2017 compared to a 10% fall in 2016. The fall was again led by the power sector due in large part to Scotland’s first full year of coal-free electricity generation. Recent performance in other sectors shows only incremental improvement at best and unless emissions reductions are delivered economy-wide Scotland is at risk of missing its new interim target of a 56% reduction in emissions by 2020.

Key findings

Setting a net-zero greenhouse gas emissions target for 2045 represents a step-change in ambition for Scotland.

The Scottish Parliament’s 2030 target to reduce emissions by 75% will be extremely challenging to meet. It must be backed up by steps to drive meaningful emissions reductions immediately.

Scotland’s Programme for Government 2019-20 alongside other recent policies sent a clear signal that the Scottish Government is taking its more ambitious targets seriously but there is much more to do.

Scotland’s ability to deliver its net-zero target is contingent on action taken in the UK and vice versa.

This brief explores recent momentum on hydrogen and evaluates potential implications for subsidies for fossil fuel-based hydrogen given the government's commitments on fossil fuel subsidies.

Spending on hydrogen has the potential to significantly influence the direction taken by the world’s energy systems. In December 2020 Canada unveiled a national hydrogen strategy following the announcement of a strengthened climate plan. The strategy emphasized both blue and green hydrogen. As the government considers whether to provide subsidies for hydrogen we recommend government:

• Ensure that any subsidies for hydrogen are in line with the government’s commitments to phase out inefficient fossil fuel subsidies by 2025 and meet net-zero by 2050.
• Thoroughly evaluate the potential efficiency of subsidies for hydrogen against robust social environmental and economic criteria. • Improve transparency by publicly reporting on direct spending and tax expenditures for hydrogen production.
• Follow international best practices being set by Canada’s peers. For example Germany and Spain have laid out hydrogen strategies prioritizing green hydrogen.

Based on IISD's analysis subsidies for hydrogen based on natural gas without significant levels of carbon capture and storage (CCS) should not be eligible for government assistance. Subsidies for blue hydrogen should only occur if blue hydrogen can meet the same level of environmental performance (including emission intensity) and is at or below the cost of green hydrogen.

This brief is one of three International Institute for Sustainable Development (IISD) policy briefs in its Recovery Through Reform series which assesses how efforts to achieve a green recovery from COVID-19 in Canada rely on—and can contribute to—fossil fuel subsidy reform.

Hydrogen has been identified as a potential energy vector to decarbonise the transport and chemical sectors and achieve global greenhouse gas reduction targets. Despite ongoing efforts hydrogen technologies are often assessed focusing on their global warming potential while overlooking other impacts or at most including additional metrics that are not easily interpretable. Herein a wide range of alternative technologies have been assessed to determine the total cost of hydrogen production by coupling life-cycle assessments with an economic evaluation of the environmental externalities of production. By including monetised values of environmental impacts on human health ecosystem quality and resources on top of the levelised cost of hydrogen production an estimation of the “real” total cost of hydrogen was obtained to transparently rank the alternative technologies. The study herein covers steam methane reforming (SMR) coal and biomass gasification methane pyrolysis and electrolysis from renewable and nuclear technologies. Monetised externalities are found to represent a significant percentage of the total cost ultimately altering the standard ranking of technologies. SMR coupled with carbon capture and storage emerges as the cheapest option followed by methane pyrolysis and water electrolysis from wind and nuclear. The obtained results identify the “real” ranges for the cost of hydrogen compared to SMR (business as usual) by including environmental externalities thereby helping to pinpoint critical barriers for emerging and competing technologies to SMR.

Since the COP 21 meeting in Paris in December 2015 there has been a growing realisation that with the long-term objective that the energy system should be approaching carbon-neutrality by 2050 continuing to burn significant quantities of fossil-derived natural gas will not be sustainable. If existing natural gas infrastructure is to avoid becoming stranded assets plans to decarbonise the gas system need to be developed as a matter of urgency in the next three to five years given the typical life expectancy of such assets of 20 years or more. One of the options to decarbonise gas is “power-to-gas”: production of hydrogen or renewable methane via electrolysis using surplus renewable electricity. This Energy Insight reviews the status of power-to-gas and makes an assessment of potential future development pathways and the role which it could play in decarbonising the energy system.

The use of hydrogen energy and the associated technologies is expected to increase in the coming years. The success of hydrogen energy technology (HET) is however dependent on public acceptance of the technology. Developing this new industry in a socially responsible way will require an understanding of the psychology factors that may facilitate or impede its public acceptance. This paper reviews 27 quantitative studies that have explored the relationship between psychological factors and HET acceptance. The findings from the review suggest that the perceived effects of the technology (i.e. the perceived benefits costs and risks) and the associated emotions are strong drivers of HET acceptance. This paper does though highlight some limitations with past research that make it difficult to make strong conclusions about the factors that influence HET acceptance. The review also reveals that few studies have investigated acceptance of different types of HET beyond a couple of applications. The paper ends with a discussion about directions for future research and highlights some practical implications for messaging and policy.
