Policy & Socio-Economics

In response to the urgent need to mitigate climate change via net-zero targets many nations are renewing their interest in clean hydrogen as a net-zero energy carrier. Although clean hydrogen can be directly used in various sectors for deep decarbonization the relatively low energy density and high production costs have raised doubts as to whether clean hydrogen development is worthwhile. Here we improve on the GCAM model by including a more comprehensive and detailed representation of clean hydrogen production distribution and demand in all sectors of the global economy and simulate 25 scenarios to explore the costeffectiveness of integrating clean hydrogen into the global energy system. We show that due to costly technical obstacles clean hydrogen can only provide 3%–9% of the 2050 global final energy use. Nevertheless clean hydrogen deployment can reduce overall energy decarbonization costs by 15%–22% mainly via powering ‘‘hard-to-electrify’’ sectors that would otherwise face high decarbonization expenditures. Our work provides practical references for cost-effective clean hydrogen planning.

Hydrogen’s wide availability and versatile production methods establish it as a primary green energy source driving substantial interest among the public industry and governments due to its future fuel potential. Notable investment is directed toward hydrogen research and material innovation for transmission storage fuel cells and sensors. Ensuring safe and dependable hydrogen facilities is paramount given the challenges in accident control. Addressing material compatibility issues within hydrogen systems remains a critical focus. Challenges roadmaps and scenarios steer long-term planning and technology outlooks. Strategic visions align actions and policies encompassing societal and ecological dimensions. The confluence of hydrogen’s promise with material progress holds the prospect of reshaping our energy landscape sustainably. Forming collective future perspectives to foresee this emerging technology’s potential benefits is valuable. Our review article comprehensively explores the forthcoming challenges in hydrogen technology. We extensively examine the challenges and opportunities associated with hydrogen production incorporating CO2 capture technology. Furthermore the interaction of materials and composites with hydrogen particularly in the context of hydrogen transmission pipeline and infrastructure are discussed to understand the interplay between materials and hydrogen dynamics. Additionally the exploration extends to the embrittlement phenomena during storage and transmission coupled with a comprehensive examination of the advancements and hurdles intrinsic to hydrogen fuel cells. Finally our exploration encompasses addressing hydrogen safety from an industrial perspective. By illuminating these dimensions our article provides a panoramic view of the evolving hydrogen landscape.

Beyond its role as an energy vector a growing number of natural hydrogen sources and reservoirs are being discovered all over the globe which could represent a clean energy source. Although the hydrogen amounts in reservoirs are uncertain they could be vast and they could help decarbonize energy-intensive economic sectors and facilitate the energy transition. Natural hydrogen is mainly produced through a geochemical process known as serpentinization which involves the reaction of water with low-silica ferrous minerals. In favorable locations the hydrogen produced can become trapped by impermeable rocks on its way to the atmosphere forming a reservoir. The safe exploitation of numerous natural hydrogen reservoirs seems feasible with current technology and several demonstration plants are being commissioned. Natural hydrogen may show variable composition and require custom separation purification storage and distribution facilities depending on the location and intended use. By investing in research in the mid-term more hydrogen sources could become exploitable and geochemical processes could be artificially stimulated in new locations. In the long term it may be possible to leverage or engineer the interplay between microorganisms and geological substrates to obtain hydrogen and other chemicals in a sustainable manner.

To achieve carbon neutrality in Japan by 2050 renewable energy needs to be used as the main energy source. Based on the constraints of various renewable energies the importance of hydrogen cannot be ignored. This study aimed to investigate the diffusion of hydrogen demand technologies in various sectors and used projections and assumptions to investigate the hydrogen supply side. By performing simulations with the E3ME-FTT model and comparing various policy scenarios with the reference scenario the economic and environmental impacts of the policy scenarios for hydrogen diffusion were analyzed. Moreover the impact of realizing carbon neutrality by 2050 on the Japanese economy was evaluated. Our results revealed that large-scale decarbonization via hydrogen diffusion is possible (90% decrease of CO2 emissions in 2050 compared to the reference) without the loss of economic activity. Additionally investments in new hydrogen-based and other low-carbon technologies in the power sector freight road transport and iron and steel industry can improve the gross domestic product (1.6% increase in 2050 compared to the reference) as they invoke economic activity and require additional employment (0.6% increase in 2050 compared to the reference). Most of the employment gains are related to decarbonizing the power sector and scaling up the hydrogen supply sector while a lot of job losses can be expected in the mining and fossil fuel industries.

Currently meeting the global energy demand is largely dependent on fossil fuels such as natural gas coal and oil. Fossil fuels represent a danger to the Earth’s environment and its biological systems. The utilisation of these fuels results in a rise in atmospheric CO2 levels which in turn triggers global warming and adverse changes in the climate. Furthermore these represent finite energy resources that will eventually deplete. There is a pressing need to identify and harness renewable energy sources as a replacement for fossil fuels in the near future. This shift is expected to have a minimal environmental impact and would contribute to ensuring energy security. Hydrogen is considered a highly desirable fuel option with the potential to substitute depleting hydrocarbon resources. This concise review explores diverse methods of renewable hydrogen production with a primary focus on solar wind geothermal and mainly water-splitting techniques such as electrolysis thermolysis photolysis and biomass-related processes. It addresses their limitations and key challenges hampering the global hydrogen economy’s growth including clean value chain creation storage transportation production costs standards and investment risks. The study concludes with research recommendations to enhance production efficiencies and policy suggestions for governments to mitigate investment risks while scaling up the hydrogen economy.

Energy transition will reshape the power sector and hydrogen is a key energy carrier that could contribute to energy security. The inclusion of sustainability criteria is crucial for the adequate design/deployment of resilient hydrogen networks. While cost and environmental metrics are commonly included in hydrogen models social aspects are rarely considered. This paper aims to identify the social criteria related to the hydrogen economy by using a systematic hybrid literature review. The main contribution is the identification of twelve social aspects which are described ranked and discussed. “Accessibility” “Information” “H2 markets” and “Acceptability” are now emerging as the main themes of hydrogen-related social research. Identified gaps are e.g. lack of the definition of the value of H2 for society insufficient research for “socio-political” aspects (e.g. geopolitics wellbeing) scarce application of social lifecycle assessment and the low amount of works with a focus on social practices and cultural issues.

Dihydrogen (H2) commonly named ‘hydrogen’ is increasingly recognised as a clean and reliable energy vector for decarbonisation and defossilisation by various sectors. The global hydrogen demand is projected to increase from 70 million tonnes in 2019 to 120 million tonnes by 2024. Hydrogen development should also meet the seventh goal of ‘affordable and clean energy’ of the United Nations. Here we review hydrogen production and life cycle analysis hydrogen geological storage and hydrogen utilisation. Hydrogen is produced by water electrolysis steam methane reforming methane pyrolysis and coal gasification. We compare the environmental impact of hydrogen production routes by life cycle analysis. Hydrogen is used in power systems transportation hydrocarbon and ammonia production and metallugical industries. Overall combining electrolysis-generated hydrogen with hydrogen storage in underground porous media such as geological reservoirs and salt caverns is well suited for shifting excess of-peak energy to meet dispatchable on-peak demand.

In order to achieve the EU’s target of 55% carbon reduction by 2030 hydrogen will have to make a key contribution to the energy mix. With many applications in industrial heat mobility power and chemical refineries hydrogen can be used to decarbonise where electrification is not possible. Equinor is a broad energy company with 21000 employees developing oil gas wind and solar energy in more than 30 countries worldwide. Equinor have been at the forefront of promoting hydrogen projects in Europe and developing low-carbon hydrogen solutions. In this episode Johan Leuraers Chief Consultant - Policy and Regulatory Affairs at Equinor and John Williams Head of Hydrogen Expertise Cluster at AFRY Management Consulting join us to discuss the main barriers to the uptake of hydrogen and the next steps to kick-start the hydrogen economy.

Welcome to our Future Energy Scenarios. These scenarios which stimulate debate and help inform the decisions that will shape our energy future have never been more important – especially when you consider the extent to which the energy landscape is being transformed.

Accommodating renewables on the electricity grid may hinder development opportunities for offshore wind farms (OWFs) as they begin to experience significant curtailment or constraint. However there is potential to combine investment in OWFs with Power-to-Gas (PtG) converting electricity to hydrogen via electrolysis for an alternative/complementary revenue. Using historic wind speed and simulated system marginal costs data this work models the electricity generated and potential revenues of a 504 MW OWF. Three configurations are analysed; (1) all electricity is sold to the grid (2) all electricity is converted to hydrogen and sold and (3) a hybrid system where power is converted to hydrogen when curtailment occurs and/or when the system marginal cost is low with the effect of curtailment analysed in each scenario. These represent the status quo a potential future configuration and an innovative business model respectively. The willingness of an investor to build PtG are determined by changes to the net present value (NPV) of a project. Results suggest that configuration (1) is most profitable and that curtailment mitigation alone is not sufficient to secure investment in PtG. By acting as an artificial floor in the electricity price a hybrid configuration (3) is promising and increases NPV for all hydrogen values greater than €4.2/kgH2. Hybrid system attractiveness increases with curtailment only if the hydrogen value is significantly above the levelised cost of €3.77/kgH2. In order for an investor to choose to pursue configuration (2) the offshore wind farm would have to anticipate 8.5% curtailment and be able to receive €4.5/kgH2 or 25% curtailment and receive €4/kgH2. The capital costs and discount rates are the most sensitive parameters and ambitious combinations of technology improvements could produce a levelised cost of €3/kgH2.

The holistic green energy transition of non-interconnected islands faces several challenges if all the energy sectors are included i.e. electricity heating/cooling and mobility. On the one hand the penetration of renewable energy systems (RES) is limited due to design restrictions with respect to the peak demand. On the other hand energy-intensive heating and mobility sectors pose significant challenges and may be difficult to electrify. The focus of this study is on implementing a hybrid Wind–PV system on the non-interconnected island of Anafi (Greece) that utilizes surplus renewable energy production for both building heating through heat pumps and hydrogen generation. This comprehensive study aims to achieve a holistic green transition by addressing all three main sectors—electricity heating and transportation. The produced hydrogen is utilized to address the energy needs of the mobility sector (H2 mobility) focusing primarily on public transportation vehicles (buses) and secondarily on private vehicles. The overall RES production was modeled to be 91724 MWh with a RES penetration of 84.68%. More than 40% of the produced electricity from RES was in the form of excess electricity that could be utilized for hydrogen generation. The modeled generated hydrogen was simulated to be more than 40 kg H2/day which could cover all four bus routes of the island and approximately 200 cars for moderate use i.e. traveled distances of less than 25 km/day for each vehicle.

Hydrogen technologies are promising candidates of new energy technologies for electric power load smoothing. However regardless of long-term public investment hydrogen economy has not been realized. In Japan the National Research and Development Institute of New Energy and Industrial Technology Development Organization (NEDO) a public research-funding agency has invested more than 200 billion yen in the technical development of hydrogen-related technologies. However hydrogen technologies such as fuel cell vehicles (FCVs) have not been disseminated yet. Continuous and strategic research and development (R&D) are needed but there is a lack of expertise in this field. In this study the transition of the budgetary allocations by NEDO were analyzed by classifying NEDO projects along the hydrogen supply chain and research stage. We found a different R&D focus in different periods. From 2004 to 2007 empirical research on fuel cells increased with the majority of research focusing on standardization. From 2008 to 2011 investment in basic research of fuel cells increased again the research for verification of fuel cells continued and no allocation for research on hydrogen production was confirmed. Thereafter the investment trend did not change until around 2013 when practical application of household fuel cells (ENE-FARM) started selling in 2009 in terms of hydrogen supply chain. Hydrogen economy requires a different hydrogen supply infrastructure that is an existing infrastructure of city gas for ENE-FARM and a dedicated infrastructure for FCVs (e.g. hydrogen stations). We discussed the possibility that structural inertia could prevent the transition to investing more in hydrogen infrastructure from hydrogen utilization technology. This work has significant implications for designing national research projects to realize hydrogen economy.

Meeting the Paris Agreement's goal to limit global warming to well below 2 °C and pursuing efforts towards 1.5 °C is likely to require more rapid and fundamental energy system changes than the previously-agreed 2 °C target. Here we assess over 200 integrated assessment model scenarios which achieve 2 °C and well-below 2 °C targets drawn from the IPCC's fifth assessment report database combined with a set of 1.5 °C scenarios produced in recent years. We specifically assess differences in a range of near-term indicators describing CO2 emissions reductions pathways changes in primary energy and final energy across the economy's major sectors in addition to more detailed metrics around the use of carbon capture and storage (CCS) negative emissions low-carbon electricity and hydrogen.

Our Future Energy Scenarios (FES) outline four different credible pathways for the future of energy over the next 30 years. Based on input from over 600 experts the report looks at the energy needed in Britain across electricity and gas - examining where it could come from how it needs to change and what this means for consumers society and the energy system itself.

Austria is committed to the net-zero climate goal along with the European Union. This requires all sectors to be decarbonized. Hereby hydrogen plays a vital role as stated in the national hydrogen strategy. A report commissioned by the Austrian government predicts a minimum hydrogen demand of 16 TWh per year in Austria in 2040. Besides hydrogen imports domestic production can ensure supply. Hence this study analyses the levelized cost of hydrogen for an off-grid production plant including a proton exchange membrane electrolyzer wind power and solar photovoltaics in Austria. In the first step the capacity factors of the renewable electricity sources are determined by conducting a geographic information system analysis. Secondly the levelized cost of electricity for wind power and solarphotovoltaics plants in Austria is calculated. Thirdly the most cost-efficient portfolio of wind power and solar photovoltaics plants is determined using electricity generation profiles with a 10-min granularity. The modelled system variants differ among location capacity factors of the renewable electricity sources and the full load hours of the electrolyzer. Finally selected variables are tested for their sensitivities. With the applied model the hydrogen production cost for decentralized production plants can be calculated for any specific location. The levelized cost of hydrogen estimates range from 3.08 EUR/kg to 13.12 EUR/kg of hydrogen whereas it was found that the costs are most sensitive to the capacity factors of the renewable electricity sources and the full load hours of the electrolyzer. The novelty of the paper stems from the model applied that calculates the levelized cost of renewable hydrogen in an off-grid hydrogen production system. The model finds a cost-efficient portfolio of directly coupled wind power and solar photovoltaics systems for 80 different variants in an Austria-specific context.

Legislation regulating the sustainability requirements for hydrogen technologies relies more and more on life cycle assessments (LCAs). Due to different scopes and development processes different pieces of EU legislation refer to different LCA methodologies with differences in the way multifunctional processes (i.e. co-productions recycling and energy recovery) are treated. These inconsistencies arise because incentive mechanisms are not standardized across sectors even though the end product hydrogen remains the same. The goal of this paper is to compare the life-cycle greenhouse gas (GHG) emissions of hydrogen from four production pathways depending on the multifunctional approach prescribed by the different EU policies (e.g. using substitution or allocation). The study reveals a large variation in the LCA results. For instance the life-cycle GHG emissions of hydrogen co-produced with methanol is found to vary from 1 kg CO2-equivalent/kg H2 (when mass allocation is considered) to 11 kg CO2-equivalent/kg H2 (when economic allocation is used). These inconsistencies could affect the market (e.g. hydrogen from a certain pathway could be considered sustainable or unsustainable depending on the approach) and the environment (e.g. pathways that do not lead to a global emission reduction could be promoted). To mitigate these potential negative effects we urge for harmonized and strict guidelines to assess the life-cycle GHG emissions of hydrogen technologies in an EU policy context. Harmonization should cover international policies too to avoid the same risks when hydrogen will be traded based on its GHG emissions. The appropriate methodological approach for each production pathway should be chosen by policymakers in collaboration with the LCA community and stakeholders from the industry based on the potential market and environmental consequences of such choice.

Electrification of the transportation sector is one of the main drivers in the decarbonization of energy and mobility systems and it is a way to ensure security of energy supply. Public bus fleets can assist in achieving fast reduction of CO2 emissions. This article provides an analysis of a unique real-world dataset to support decision makers in the decarbonization of public fleets and interlink it with the social acceptance of drivers. Data was collected from 21 fuel cell and electric buses. The tank-to-wheel efficiency results of fuel cell electric buses (FCEB) are much lower than that of battery electric buses (BEB) and there is a higher variation in consumption for BEBs compared to FCEBs. Both technologies permit a strong reduction in CO2 emissions compared to conventional buses. There is a high level of acceptance of drivers which are likely to support the transition towards zero-emission buses introduced by the management.

The main problem confronting the world is human-caused climate change which is intrinsically linked to the need for energy both now and in the future. Renewable (green) energy has been proposed as a future solution and many renewable energy technologies have been developed for different purposes. However progress toward net zero carbon emissions by 2050 and the role of renewable energy in 2050 are not well known. This paper reviews different renewable energy technologies developed by different researchers and their potential and challenges to date and it derives lessons for world and especially African policymakers. According to recent research results the mean global capabilities for solar wind biogas geothermal hydrogen and ocean power are 325 W 900 W 300 W 434 W 150 W and 2.75 MWh respectively and their capacities for generating electricity are 1.5 KWh 1182.5 KWh 1.7 KWh 1.5 KWh 1.55 KWh and 3.6 MWh respectively. Securing global energy leads to strong hope for meeting the Sustainable Development Goals (SDGs) such as those for hunger health education gender equality climate change and sustainable development. Therefore renewable energy can be a considerable contributor to future fuels.

Because of the pressure to meet carbon neutrality targets carbon reduction has become a challenge for fossil fuel resource-based regions. Even though China has become the most active country in carbon reduction its extensive energy supply and security demand make it difficult to turn away from its dependence on coal-based fossil energy. This paper analyzes the Chinese coal capital—Shanxi Province—to determine whether the green low-carbon energy transition should be focused on coal resource areas. In these locations the selection and effect of transition tools are key to ensuring that China meets its carbon reduction goal. Due to the time window of clean coal utilization the pressure of local governments and the survival demands of local high energy consuming enterprises Shanxi Province chose hydrogen as its important transition tool. A path for developing hydrogen resources has been established through lobbying and corporative influence on local and provincial governments. Based on such policy guidance Shanxi has realized hydrogen applications in large-scale industrial parks regional public transport and the iron and steel industry. This paper distinguishes between the development strategies of gray and green hydrogen. It shows that hydrogen can be an effective development model for resource-based regions as it balances economic stability and energy transition.

Chile abundant in solar and wind energy resources presents significant potential for the production of green hydrogen a promising renewable energy vector. However realizing this potential requires an understanding of the most suitable locations for the installation of green hydrogen industries. This study proposes a quantitative methodology that identifies and ranks potential public lands for industrial use based on a range of technical parameters (such as solar and wind availability) and socio-environmental considerations (including land use restrictions and population density). The results reveal optimal locations that can facilitate informed sustainable decision-making for large-scale green hydrogen implementation in Chile. While this methodology does not replace project-specific technical or environmental impact studies it provides a flexible general classification to guide initial site selection. Notably this approach can be applied to other regions worldwide with abundant solar and wind resources such as Australia and Northern Africa promoting more effective and sustainable global decision-making for green hydrogen production.

This report aims to summarise the status of the European hydrogen policies and standards landscape. It is based on the information available at the European Hydrogen Observatory (EHO) platform the leading source of data and information on hydrogen in Europe (EU27 EFTA and the UK) providing an overview of the European and national policies legislations strategies and codes and standards which impact the deployment of hydrogen technologies and infrastructures. The EHO database covers a total of 29 EU policies and legislations that directly or indirectly affect the development and deployment of hydrogen technologies. To achieve its net zero ambitions the EU started with cross-cutting strategies such as the EU Green Deal and the EU Hydrogen Strategy setting forward roadmaps and targets that are to be achieved in the near future. As a next step the EU has developed legislations such as those bundled in the Fit for 55 package to meet the targets they have put forward. The implemented legislations including funding vehicles and initiatives have an impact on the whole value chain of hydrogen including production transport storage and distribution and end-uses. At national level as of July 2023 63% of the European countries have successfully published their national strategies in the hydrogen sector while 6% of the countries are currently in the draft stage. Several European countries have strategically incorporated quantitative indicators within their national strategies outlining their targets and estimates across the hydrogen value chain. This deliberate approach reflects a commitment to providing clear and measurable goals within their hydrogen strategies. A target often used in the national strategies is on electrolyser capacity as an effort to enhance the domestic renewable hydrogen production. Germany took the lead with an ambitious goal of achieving 10 GW by 2030 followed by France (6.5 GW) and Denmark (4 - 6 GW). Other targets that some of the countries use in their strategies are on the number of hydrogen refuelling stations fuel cell electric vehicles and total (renewable) hydrogen demand. A few countries also have targets on renewable hydrogen uptake in industry and hydrogen injection limit in the transmission grid. To monitor the policies and legislation that are adopted on a national level across the hydrogen value chain a survey was launched with national experts which was validated by Hydrogen Europe. In total 28 European countries have participated to the survey. On production the survey revealed that 61% of country specialists report that their country provides support for capital expenditure (CAPEX) in the development of renewable or low-carbon hydrogen production plants. Moreover 7 countries also provide support for operational expenditure (OPEX). Furthermore 8 countries have instituted official 6 permitting guidelines for hydrogen production projects while 5 countries have enacted a legal act or established an agency serving as a single point of contact for hydrogen project developers. For transmission only two countries reported to provide support schemes for hydrogen injection. Several countries have policies in place that clearly define the hydrogen limit in their transmission grid for now and in the future ranging from 0.02% up to 15% while a few countries define within their policies the operation of hydrogen storage facilities. On end-use the majority of countries totalling 71% reported to have implemented support schemes aimed at promoting the adoption of hydrogen in the mobility sector. Purchase subsidies stand out as the predominant form of support for fuel cell electric vehicles (FCEVs) with implementation observed in 17 countries. In the context of support schemes for stationary fuel applications for heating or power generation only two countries have adopted such measures. A slightly larger group of four countries do provide support for the deployment of residential and commercial heating systems utilizing hydrogen. For hydrogen end-use in industry a total of 9 countries reported to provide support schemes with a major focus on ammonia production (8) and the chemicals industry (7). On the topic of technology manufacturing 7 countries have reported to have support schemes of which grants emerge as the mainly used method (4). Exploring the latest advancements into European codes and standards relevant to the deployment of hydrogen technologies and infrastructures a total of 11 standards have been revised and developed between January 2022 and September 2023. This includes standards covering the following areas: 6 for fuel cell technologies 2 for gas cylinders 2 for road vehicles and 1 for hydrogen refuelling. Moreover 5 standards were published since September 2023 which will be added to the EHO database in its next update. This includes ISO/TS 19870:2023 which sets a methodology for determining the greenhouse gas emissions associated with the production conditioning and transport of hydrogen to consumption gate. This landmark standard which was unveiled at COP28 aims to act as a foundation for harmonization safety interoperability and sustainability across the hydrogen value chain.

This report aims to summarise the status of the European hydrogen market landscape. It is based on the information available at the European Hydrogen Observatory (EHO) platform the leading source of data and information on hydrogen in Europe (EU27 EFTA and the UK) providing a full overview of the hydrogen market and the deployment of clean hydrogen technologies. As of the end of 2022 a total of 476 operational hydrogen production facilities across Europe boasting a cumulative hydrogen production capacity of approximately 11.30 Mt were identified. Notably the largest share of this capacity is contributed by key European countries including Germany the Netherlands Poland Italy and France which collectively account for 56% of the total hydrogen capacity. The hydrogen consumption in Europe has been estimated at approximately 8.23 Mt reflecting an average capacity utilisation rate of 73%. It's worth highlighting that conventional hydrogen production methods encompassing reforming by-product production from ethylene and styrene and by-product electrolysis collectively yield 11.28 Mt of hydrogen capacity. These conventional processes are distributed across 376 production facilities constituting 99.9% of the total production capacity in 2022. Throughout the year 2022 there were no newly commissioned hydrogen production facilities that integrated carbon capture technology into their operations. Additionally a notable presence of water electrolysis-based hydrogen production projects in Europe was identified. There was a total of 97 water electrolysis projects with 67 of them having a minimum capacity of 0.5 MW resulting in a cumulative production capacity of 174.28 MW. Furthermore 46 such projects were found to be under construction and are anticipated to contribute an additional 1199.07 MW of water electrolysis capacity upon becoming operational with the estimated timeframe ranging from January 2023 to 2025. A significant 87% of the total hydrogen production capacity in Europe is dedicated to onsite captive consumption indicating that it is primarily produced and used within the facility. The remaining 13% of capacity is specifically allocated for external distribution and sale characterizing what's known as merchant consumption. Despite the prevailing dominance of captive hydrogen production within Europe it's noteworthy that thousands of metric tonnes of hydrogen are already being traded and distributed across the continent. These transfers often occur through dedicated hydrogen pipelines or transportation via trucks. In 2022 an example of this growing trend was the hydrogen export from Belgium to the Netherlands which emerged as the single most significant hydrogen flow between European countries constituting a substantial 75% of all hydrogen traded in Europe. Belgium earned distinction as Europe's leading hydrogen exporter with 78% of the hydrogen that flowed between European countries originating 6 from its facilities. Conversely the Netherlands played a pivotal role as Europe's primary hydrogen importer accounting for an impressive 76% of the hydrogen imported into the continent. The rise of the clean hydrogen market in Europe coupled with the European Union's ambition to import 10 Mt of renewable hydrogen from non-EU sources by 2030 is expected to drive an increase in hydrogen flows both exports and imports among European countries. In 2022 the total demand for hydrogen in Europe was estimated to be 8.19 Mt. The biggest share of hydrogen demand comes from refineries which were responsible for 57% of total hydrogen use (4.6 Mt) followed by the ammonia industry with 24% (2.0 Mt). Together these two sectors consumed 81% of the total hydrogen consumption in Europe. Clean hydrogen demand while currently making up less than 0.1% of the overall hydrogen demand is notably driven by the mobility sector. Forecasts project an impressive growth trajectory in total hydrogen demand for Europe over the coming decades. Projections show a remarkable 127% surge from 2030 to 2040 followed by a substantial 63% increase from 2040 to 2050. Considering the current hydrogen demand there is a projected 51% increase until 2030. Throughout the three decades under examination the industrial sector is anticipated to maintain its predominant position consistently demonstrating the highest demand for hydrogen. However this conclusion refers to average values and variations that may exist. The total number of Hydrogen Fuel Cell Electric Vehicles (FCEV) registrations in Europe in 2022 was estimated at 1537 units. In comparison to the previous year the number of registrations increased by 31%. This surge in registrations has had a pronounced impact on the overall FCEV fleet's evolution in Europe which increased from 4050 units to 5570 (+38%). Notably passenger cars dominated the landscape constituting 86% of the total FCEV fleet. Exploring the latest advancements in hydrogen infrastructure across Europe in 2022 the hydrogen distribution network comprised spanning a total length of 1569 km. Within Europe the largest networks are situated in Belgium and Germany at 600 km and 400 km respectively. Of particular importance is the cross-border network of France Belgium and the Netherlands spanning a total of 964 km. To keep pace with the rising number of Fuel Cell Electric Vehicles (FCEVs) on European roads and promote their wider integration it is key to ensure sufficient accessibility to refuelling infrastructure. Consequently many countries are endorsing the establishment of hydrogen refuelling stations (HRS) so that they are publicly accessible on a nationwide scale. More recharging and refuelling stations for alternative fuels will be deployed in the coming years across Europe enabling the transport sector to significantly reduce its carbon footprint following the adoption of the alternative fuel infrastructure regulation (AFIR). Part of the regulation's main target is that hydrogen refuelling stations serving both cars and lorries must be deployed from 7 2030 onwards in all urban nodes and every 200 km along the TEN-T core network. Since 2015 the total number of operational and publicly accessible HRS in Europe has grown at an accelerated pace from 38 to 178 by the summer of 2023. Germany takes the lead having the largest share at approximately 54% of the total number of HRS with 96 stations currently operational. The majority of the HRS (89%) are equipped with 700 bar car dispensers. In 2022 the levelized production costs of hydrogen generated through Steam Methane Reforming (SMR) in Europe averaged approximately 6.23 €/kg H2. When incorporating a carbon capture system the average cost of hydrogen production via SMR in Europe increased to 6.38 €/kg H2. Additionally the production costs of hydrogen in Europe for 2022 utilizing grid electricity averaged 9.85 €/kg H2. Hydrogen production costs through electrolysis with a direct connection to a renewable energy source had an average estimated cost of 6.86 €/kg. As of May 2023 Europe's operational water electrolyser manufacturing capacity stands at 3.11 GW/year with an additional 2.64 GW planned by the end of 2023. Alkaline technologies make up 53% of the total capacity. Looking ahead to 2025 ongoing projects are expected to raise the total capacity to 7.65 GW/year. Fuel cell deployment in Europe has showed an increasing trend over the past decade. The total number of shipped fuel cells were forecasted on around 11200 units in 2021 and a total capacity of 190 MW. The most significant increase in capacity occurred between 2018 and the forecast of 2021 (+148.8 MW).

Purpose: The purpose of the hydrogen supply and demand data stream is to track changes in the structure of hydrogen supply capacity and demand in Europe. This report is mainly focused on presenting the current landscape that will allow for future year-on-year comparisons to assess the progress Europe is making with regards to deployment of clean hydrogen production capacity as well as development of demand for clean hydrogen from emerging new hydrogen applications in industry or mobility sectors. Scope: The following report contains data about hydrogen production capacity and consumption in EU countries together with Switzerland Norway Iceland and the United Kingdom. Hydrogen production capacity is presented by country and by production technology whereas the hydrogen consumption data is presented by country and by end-use sector. The analysis undertaken for this report was completed using data reflecting end of 2019. Key Findings: The current hydrogen market (on both the demand and supply side) is dominated by ammonia and refining industries with three countries (DE NL PL) responsible for almost half of hydrogen consumption. Hydrogen is overwhelmingly produced by reforming of fossil fuels (mostly natural gas). Clean hydrogen production capacities are currently insignificant with hydrogen produced from natural gas coupled with carbon capture at 0.5% and hydrogen produced from water electrolysis at 0.14% of total production capacity.
