Public Acceptance for the Implementation of Hydrogen Self-refueling Stations
Sep 2021
Publication
The utilization of hydrogen energy is important for achieving a low-carbon society. Japan has set ambitious goals for hydrogen stations and fuel cell vehicles focusing on the introduction and dissemination of self-refuelling systems. This paper evaluates public trust in the fuel equipment and self-handling technology related to self-refuelling hydrogen stations and compares it with that for widespread gasoline stations. To this end the results of an online survey of 300 people with Japanese driver licenses are reported and analyzed. The results show that trust in the equipment and self-handling is more important for the user than trust in the fuel. In addition to introduce and disseminate new technology such as hydrogen stations users must be made aware of the risk of using the technology until it becomes as familiar as existing gasoline station technology.
Towards a Sustainable Hydrogen Economy: Optimisation-based Framework for Hydrogen Infrastructure Development
Sep 2016
Publication
This work studies the development of a sustainable hydrogen infrastructure that supports the transition towards a low-carbon transport system in the United Kingdom (UK). The future hydrogen demand is forecasted over time using a logistic diffusion model which reaches 50% of the market share by 2070. The problem is solved using an extension of SHIPMod an optimisation-based framework that consists of a multi-period spatially-explicit mixed-integer linear programming (MILP) formulation. The optimisation model combines the infrastructure elements required throughout the different phases of the transition namely economies of scale road and pipeline transportation modes and carbon capture and storage (CCS) technologies in order to minimise the present value of the total infrastructure cost using a discounted cash-flow analysis. The results show that the combination of all these elements in the mathematical formulation renders optimal solutions with the gradual infrastructure investments over time required for the transition towards a sustainable hydrogen economy.
The Role of Advanced Demand-sector Technologies and Energy Demand Reduction in Achieving Ambitious Carbon Budgets
Jan 2019
Publication
Limiting cumulative carbon emissions to keep global temperature increase to well below 2°C (and as low as 1.5°C) is an extremely challenging task requiring rapid reduction in the carbon intensity of all sectors of the economy and with limited leeway for residual emissions. Addressing residual emissions in ‘challenging-to-decarbonise’ sectors such as the industrial and aviation sectors relies on the development and commercialization of innovative advanced technologies currently still in their infancy. The aim of this study was to (a) explore the role of advanced technologies in achieving deep decarbonisation of the energy system and (b) provide technology- specific details of how rapid and deep carbon intensity reductions can be achieved in the energy demand sectors. This was done using TIAM-Grantham – a linear cost optimization model of the global energy system with a detailed representation of demand-side technologies. We find that the inclusion of advanced technologies in the demand sectors together with energy demand reduction through behavioural changes enables the model to achieve the rapid and deep decarbonisation of the energy system associated with limiting global warming to below 2°C whilst at the same time reduces reliance on negative emissions technologies by up to ∼18% compared to the same scenario with a standard set of technologies. Realising such advanced technologies at commercial scales as well as achieving such significant reductions in energy demand represents a major challenge for policy makers businesses and civil society. There is an urgent need for continued R&D efforts in the demand sectors to ensure that advanced technologies become commercially available when we need them and to avoid the gamble of overreliance on negative emissions technologies to offset residual emissions.
Hydrogen Production, Storage and Transport for Renewable Energy and Chemicals: An Environmental Footprint Assessment
Dec 2022
Publication
Hydrogen applications range from an energy carrier to a feedstock producing bulk and other chemicals and as an essential reactant in various industrial applications. However the sustainability of hydrogen production storage and transport are neither unquestionable nor equal. Hydrogen is produced from natural gas biogas aluminium acid gas biomass electrolytic water splitting and others; a total of eleven sources were investigated in this work. The environmental impact of hydrogen production storage and transport is evaluated in terms of greenhouse gas and energy footprints acidification eutrophication human toxicity potential and eco-cost. Different electricity mixes and energy footprint accounting approaches supported by sensitivity analysis are conducted for a comprehensive overview. H2 produced from acid gas is identified as the production route with the highest eco-benefit (− 41188 €/t H2) while the biomass gasification method incurred the highest eco-cost (11259 €/t H2). The water electrolysis method shows a net positive energy footprint (60.32 GJ/t H2) suggesting that more energy is used than produced. Considering the operating footprint of storage and transportation gaseous hydrogen transported via a pipeline is a better alternative from an environmental point of view and with a lower energy footprint (38 %–85%) than the other options. Storage and transport (without construction) could have accounted for around 35.5% of the total GHG footprint of a hydrogen value chain (production storage transportation and losses) if liquefied and transported via road transport instead of a pipeline. The identified results propose which technologies are less burdensome to the environment.
Labour Implications of the Net-zero Transition and Clean Energy Exports in Australia
Mar 2024
Publication
We examine the employment implications of a domestic net-zero transition and establishment of clean energy export systems for an historically significant energy exporting country through a case study of Australia. The labour impacts of a multi-decadal transition are simulated across both the domestic and export energy systems considering a wide range of energy technologies resources and activities with assessment according to occupation lifecycle stage education and skill requirements. Across all net-zero scenario pathways by mid-century the total gross employment created for the domestic and export sectors comprises 210–490 thousand jobs and 350–510 thousand jobs respectively. This represents a significant expansion of energy sector employment from the current total of 120 thousand across domestic and export sectors an increase from less than 1 % of the total Australian workforce in 2020 to 3–4 % by 2060. The need to build out energy system infrastructure at large-scale over a number of decades results in construction jobs continuing over that timeframe and a subsequent need for a large ongoing operations and maintenance workforce for new energy system assets. Those employed in domestic energy markets work primarily in utility solar PV onshore wind batteries and electricity transmission and distribution activities while export market jobs are dominated by clean hydrogen production and shipping supply chains. Crucially these export jobs are unevenly distributed across the country in regions of highest quality solar resource. All states and territories experience net job growth across each decade to 2060. However in a few sub-state regions net job losses occur in the short-term.
Value of Power-to-gas as a Flexibility Option in Integrated Electricity and Hydrogen Markets
Oct 2021
Publication
This paper analyzes the economic potential of Power-to-Gas (PtG) as a source of flexibility in electricity markets with both high shares of renewables and high external demand for hydrogen. The contribution of this paper is that it develops and applies a short-term (hourly) partial equilibrium model of integrated electricity and hydrogen markets including markets for green certificates while using a welfare-economic framework to assess the market outcomes. We find that strongly increasing the share of renewable electricity makes electricity prices much more volatile while the presence of PtG reduces this price volatility. However a large demand for hydrogen from outside the electricity sector reduces the impact of PtG on the volatility of electricity prices. In a scenario with a high external hydrogen demand PtG can deliver positive benefits for some groups as it can provide hydrogen at lower costs than Steam Methane Reforming (SMR) during hours when electricity prices are low but these positive welfare effects are outweighed by the fixed costs of PtG assets plus the costs of replacing a less expensive energy carrier (natural gas) with a more expensive one (hydrogen). Investments in PtG are profitable from a social-welfare perspective when the induced reduction in carbon emissions is valued at 150–750 euro/ton. Hence at lower carbon prices PtG can only become a valuable provider of flexibility when installation costs are significantly reduced and conversion efficiencies of electrolysers increased.

Scenario-Based Comparative Analysis for Coupling Electricity and Hydrogen Storage in Clean Oilfield Energy Supply System
Mar 2022
Publication
In response to the objective of fully attaining carbon neutrality by 2060 people from all walks of life are pursuing low-carbon transformation. Due to the high water cut in the middle and late phases of development the oilfield’s energy consumption will be quite high and the rise in energy consumption will lead to an increase in carbon emission at the same time. As a result the traditional energy model is incapable of meeting the energy consumption requirement of high water cut oilfields in their middle and later phases of development. The present wind hydrogen coupling energy system was researched and coupled with the classic dispersed oilfield energy system to produce energy for the oilfields in this study. This study compares four future energy system models to existing ones computes the energy cost and net present value of an oilfield in Northwest China and proposes a set of economic evaluation tools for oilfield energy systems. The study’s findings indicate that scenario four provides the most economic and environmental benefits. This scenario effectively addresses the issue of high energy consumption associated with aging oilfields at this point significantly reduces carbon emissions absorbs renewable energy locally and reduces the burden on the power grid system. Finally sensitivity analysis is utilized to determine the effect of wind speed electricity cost and oilfield gas output on the system’s economic performance. The results indicate that the system developed in this study can be applied to other oilfields.

Life Cycle Assessment of Hydrogen from Proton Exchange Membrane Water Electrolysis in Future Energy Systems
Jan 2019
Publication
This study discusses the potential of H2 production by proton exchange membrane water electrolysis as an effective option to reduce greenhouse gas emissions in the hydrogen sector. To address this topic a life cycle assessment is conducted to compare proton exchange membrane water electrolysis versus the reference process - steam methane reforming. As a relevant result we show that hydrogen production via proton exchange membrane water electrolysis is a promising technology to reduce CO2 emissions of the hydrogen sector by up to 75% if the electrolysis system runs exclusively on electricity generated from renewable energy sources. In a future (2050) base-load operation mode emissions are comparable to the reference system.
The results for the global warming potential show a strong reduction of greenhouse gas emissions by 2050. The thoroughly and in-depth modelled components of the electrolyser have negligible influence on impact categories; thus emissions are mainly determined by the electricity mix. With 2017 electricity mix of Germany the global warming potential corresponds to 29.5 kg CO2 eq. for each kg of produced hydrogen. Referring to the electricity mix we received from an energy model emissions can be reduced to 11.5 kg CO2 eq. in base-load operation by the year 2050. Using only the 3000 h of excess power from renewables in a year will allow for the reduction of the global warming potential to 3.3 kg CO2 eq. From this result we see that an environmentally friendly electricity mix is crucial for reducing the global warming impact of electrolytic hydrogen.

Analysis of the Existing Barriers for the Market Development of Power to Hydrogen (P2H) in Italy
Sep 2020
Publication
New technological solutions are required to control the impact of the increasing presence of renewable energy sources connected to the electric grid that are characterized by unpredictable production (i.e. wind and solar energy). Energy storage is becoming essential to stabilize the grid when a mismatch between production and demand occurs. Among the available solutions Power to Hydrogen (P2H) is one of the most attractive options. However despite the potential many barriers currently hinder P2H market development. The literature reports general barriers and strategies to overcome them but a specific analysis is fundamental to identifying how these barriers concretely arise in national and regional frameworks since tailored solutions are needed to foster the development of P2H local market. The paper aims to identify and to analyze the existing barriers for P2H market uptake in Italy. The paper shows how several technical regulatory and economic issues are still unsolved resulting in a source of uncertainty for P2H investment. The paper also suggests possible approaches and solutions to address the Italian barriers and to support politics and decision-makers in the definition and implementation of the national hydrogen strategy.
EU Hydrogen Strategy: A Case for Urgent Action Towards Implementation
Jul 2020
Publication
Interest in hydrogen as one route to the decarbonisation of energy systems has risen rapidly over the past few years with the publication of a number of hydrogen strategies from countries across the global energy economy. The momentum in Europe has increased sharply this month with the publication of an EU strategy to incorporate hydrogen into its plans for a net zero emission future. This Comment reviews the key elements of this strategy and provides an initial commentary on the main goals. We highlight the challenges that will be faced in meeting hydrogen production targets in particular via the “green hydrogen” route and analyse the plans for expanding the consumption of hydrogen in Europe. We also assess the infrastructure questions that will need to be answered if and when hydrogen takes on a greater role in the region and note the extensive state support that will be needed in the early years of the implementation of the strategy. Despite this though we applaud the ambition laid out by the EU and look forward to the provision of more detailed plans over the coming months and years.

Sustainable Offshore Oil and Gas Fields Development: Techno-economic Feasibility Analysis of Wind–hydrogen–natural Gas Nexus
Jul 2021
Publication
Offshore oil and gas field development consumes quantities of electricity which is usually provided by gas turbines. In order to alleviate the emission reduction pressure and the increasing pressure of energy saving governments of the world have been promoting the reform of oil and gas fields for years. Nowadays environmentally friendly alternatives to provide electricity are hotspots such as the integration of traditional energy and renewable energy. However the determination of system with great environmental and economic benefits is still controversial. This paper proposed a wind– hydrogen–natural gas nexus (WHNGN) system for sustainable offshore oil and gas fields development. Combining the optimization model with the techno-economic evaluation model a comprehensive evaluation framework is established for techno-economic feasibility analysis. In addition to WHNGN system another two systems are designed for comparison including the traditional energy supply (TES) system and wind–natural gas nexus (WNGN) system. An offshore production platforms in Bohai Bay in China is taken as a case and the results indicate that: (i) WNGN and WHNGN systems have significant economic benefits total investment is decreased by 5190 and 5020 million $ respectively and the WHNGN system increases 4174 million $ profit; (ii) WNGN and WHNGN systems have significant environmental benefits annual carbon emission is decreased by 15 and 40.2 million kg respectively; (iii) the system can be ranked by economic benefits as follows: WHNGN >WNGN > TES; and (iV) the WHNGN system is more advantageous in areas with high hydrogen and natural gas sales prices such as China Kazakhstan Turkey India Malaysia and Indonesia.
Progress in Reducing Emissions in Scotland: 2021 Report to Parliament
Dec 2021
Publication
This is the tenth annual Progress Report to the Scottish Parliament as required by the Climate Change (Scotland) Act 2009. This year’s report shows that in 2019 Scotland’s greenhouse emissions fell by 2% compared to 2018 and are now 44% below 1990 levels. The reductions were largely driven by the manufacturing and construction and fuel supply sectors with electricity generation remaining the biggest driver of emissions cuts over the past decade (2009-2019). The potential for further emissions savings from electricity generation has however largely run out.
The focus must now shift to ensuring that rapid emissions reductions are delivered with no further delay to allow Scotland to meet its legislated 2030 target.

Future Electricity Series Part 1 - Power from Fossil Fuels
Apr 2013
Publication
Power from Fossil Fuels analyses the role of coal and gas power generation in the UK's future power generation mix. It is the first of three reports in Carbon Connect's 2013 research inquiry the Future Electricity Series which examines what role fossil fuels renewables and nuclear can play in providing secure sustainable and affordable electricity in the UK. The report finds that significantly decarbonising the power sector by 2030 will prove the most successful strategy on energy sustainability security and affordability grounds and that switching the UK’s reliance on coal to gas generation - while using fossil fuel power stations increasingly for backup purposes - will be the most viable method of achieving this. The independent report chaired by former energy minister Charles Hendry MP and Opposition Energy and Climate Change Spokesperson in the House of Lords Baroness Worthington was compiled between January and April 2013 and received contributions from over 30 experts in academia industry Parliament and Government and was launched in Parliament on the 22nd April 2013. This independent inquiry was sponsored by the Institution of Gas Engineers and Managers
UK Low Carbon Hydrogen Standard: Guidance on the Greenhouse Gas Emissions and Sustainability Criteria
Apr 2022
Publication
The Low Carbon Hydrogen Standard sets a maximum threshold for the amount of greenhouse gas emissions allowed in the production process for hydrogen to be considered ‘low carbon hydrogen’. Compliance with the standard will help ensure new low carbon hydrogen production makes a direct contribution to our carbon reduction targets.
This guidance sets out the methodology for calculating the emissions associated with hydrogen production and the steps producers should take to prove that the hydrogen they produce is compliant with the standard.
It is for use by hydrogen producers seeking support from government schemes and policies that have adopted the standard.
The standard requires hydrogen producers to:

- calculate their greenhouse gas (GHG) emissions up to the ‘point of production’
- set out a risk mitigation plan for fugitive hydrogen emissions
- meet additional requirements for the use of biogenic inputs where relevant and as appropriate for the feedstock source and classification
Russia’s Policy Transition to a Hydrogen Economy and the Implications of South Korea–Russia Cooperation
Dec 2021
Publication
Leading countries are developing clean energy to replace fossil fuels. In this context Russia is changing its energy policy towards fostering new energy resources such as hydrogen and helium. Hydrogen will not only contribute to Russia’s financial revenue by replacing natural gas but will also provide a basis for it to maintain its dominance over the international energy market by pioneering new energy markets. Russia is aiming to produce more than two million tons of hydrogen fuel for export to Europe and Asia by 2035. However it is facing many challenges including developing hydrogen fuel storage systems acquiring the technology required for exporting hydrogen and building trust in the fuel market. Meanwhile South Korea has a foundation for developing a hydrogen industry as it has the highest capacity in the world to produce fuel cells and the ability to manufacture LNG: (liquefied natural gas) carriers. Therefore South Korea and Russia have sufficient potential to create a new complementary and reciprocal cooperation model in the hydrogen fuel field. This study examines the present and future of Russia’s energy policy in this area as well as discusses South Korea and Russia’s cooperation plans in the hydrogen fuel sector and the related implications.
Is a 100% Renewable European Power System Feasible by 2050?
Nov 2018
Publication
In this study we model seven scenarios for the European power system in 2050 based on 100% renewable energy sources assuming different levels of future demand and technology availability and compare them with a scenario which includes low-carbon non-renewable technologies. We find that a 100% renewable European power system could operate with the same level of system adequacy as today when relying on European resources alone even in the most challenging weather year observed in the period from 1979 to 2015. However based on our scenario results realising such a system by 2050 would require: (i) a 90% increase in generation capacity to at least 1.9 TW (compared with 1 TW installed today) (ii) reliable cross-border transmission capacity at least 140GW higher than current levels (60 GW) (iii) the well-managed integration of heat pumps and electric vehicles into the power system to reduce demand peaks and biogas requirements (iv) the implementation of energy efficiency measures to avoid even larger increases in required biomass demand generation and transmission capacity (v) wind deployment levels of 7.5GWy−1 (currently 10.6GWy−1) to be maintained while solar photovoltaic deployment to increase to at least 15GWy−1 (currently 10.5GWy−1) (vi) large-scale mobilisation of Europe’s biomass resources with power sector biomass consumption reaching at least 8.5 EJ in the most challenging year (compared with 1.9 EJ today) and (vii) increasing solid biomass and biogas capacity deployment to at least 4GWy−1 and 6 GWy−1 respectively. We find that even when wind and solar photovoltaic capacity is installed in optimum locations the total cost of a 100% renewable power system (∼530 €bn y−1) would be approximately 30% higher than a power system which includes other low-carbon technologies such as nuclear or carbon capture and storage (∼410 €bn y−1). Furthermore a 100% renewable system may not deliver the level of emission reductions necessary to achieve Europe’s climate goals by 2050 as negative emissions from biomass with carbon capture and storage may still be required to offset an increase in indirect emissions or to realise more ambitious decarbonisation pathways.
Modelling a Highly Decarbonised North Sea Energy System in 2050: a Multinational Approach
Dec 2021
Publication
The North Sea region located in the Northwest of Europe is expected to be a frontrunner in the European energy transition. This paper aims to analyse different optimal system configurations in order to meet net-zero emission targets in 2050. Overall the paper presents two main contributions: first we develop and introduce the IESA-NS model. The IESA-NS model is an optimization integrated energy system model written as a linear problem. The IESA-NS model optimizes the long-term investment planning and short-term operation of seven North Sea region countries (Belgium Denmark Germany the Netherlands Norway Sweden and the United Kingdom). The model can optimize multiple years simultaneously accounts for all the national GHG emissions and includes a thorough representation of all the sectors of the energy system. Second we run several decarbonisation scenarios with net-zero emission targets in 2050. Relevant parameters varied to produce the scenarios include biomass availability VRE potentials low social acceptance of onshore VRE ban of CCUS or mitigation targets in international transport and industry feedstock. Results show a large use of hydrogen when international transport emissions are considered in the targets (5.6 EJ to 7.3 EJ). Electrolysis is the preferred pathway for hydrogen production (up to 6.4 EJ) far ahead of natural gas reforming (up to 2.2 EJ). Allowing offshore interconnectors (e.g. meshed offshore grid between the Netherlands Germany and the United Kingdom) permits to integrate larger amounts of offshore wind (122 GW to 191 GW of additional capacity compared to reference scenarios) while substantially increasing the cross-border interconnection capacities (up to 120 GW). All the biomass available is used in the scenarios across multiple end uses including biofuel production (up to 3.5 EJ) high temperature heat (up to 2.5 EJ) feedstock for industry (up to 2 EJ) residential heat (up to 600 PJ) and power generation (up to 900 PJ). In general most of the results justify the development of multinational energy system models in which the spatial coverage lays between national and continental models.
The Role of Hydrogen in the Visegrad Group Approach to Energy Transition
Oct 2022
Publication
Hydrogen is an energy carrier in which hopes are placed for an easier achievement of climate neutrality. Together with electrification energy efficiency development and RES hydrogen is expected to enable the ambitious energy goals of the European Green Deal. Hence the aim of the article is to query the development of the hydrogen economy in the Visegrad Group countries (V4). The study considers six diagnostic features: sources of hydrogen production hydrogen legislation financial mechanisms objectives included in the hydrogen strategy environmental impact of H2 and costs of green hydrogen investments. The analysis also allowed to indicate the role that hydrogen will play in the energy transition process of the V4 countries. The analysis shows that the V4 countries have similar approaches to the development of the hydrogen market but the hydrogen strategies published by each of the Visegrad countries are not the same. Each document sets goals based on the hydrogen production to date and the specifics of the domestic energy and transport sectors as there are no solutions that are equally effective for all. Poland’s hydrogen strategy definitely stands out the strongest.
