Outlook Report: Green Hydrogen Market in Europe

Introduction and Overview

The European green hydrogen sector is evolving from an early stage policy driven concept into a central pillar of the continent’s long term decarbonization strategy. Over the last five years, political commitments, capital allocations, cost declines in electrolyzer technology, and growing corporate appetite for low carbon fuels have all converged to transform what was once a niche demonstration space into an emerging industrial market. Even so, the sector remains in a transitional phase where long term potential is exceptionally strong, but near term execution remains difficult and uneven. Investors must therefore view the space as a maturing but volatile opportunity where realistic expectations, careful exposure selection, and a clear understanding of regulatory dynamics are essential. This report will provide an examination of the industry’s size, technological foundations, growth drivers, headwinds, commercial readiness, and investment landscape, with the goal of supporting an informed evaluation of the European green hydrogen market and investment potential.

Green hydrogen occupies a unique position within Europe’s broader clean energy transition. Unlike solar or wind, which primarily compete in power generation markets, green hydrogen is aimed at decarbonizing the industrial and transport sectors that are the most difficult to electrify directly. These sectors include steelmaking, ammonia and fertilizer production, long distance shipping, synthetic fuel manufacturing, and heavy duty transport. As such, green hydrogen has become a focal point for both climate policy and industrial policy, with the European Union recognizing that large scale deployment is essential not only for its economy to reach net zero emissions, but also to reduce the reliance of Europe on Russian natural gas.

The sector remains relatively small in economic terms in 2025, however the medium and long term projections for growth are unusually large for an industrial commodity. This divergence between small present scale and large future scale is characteristic of emerging clean technology markets and helps explain why investor interest is growing even as projects face early challenges. Green hydrogen is expected to play a structural role in European energy systems, and several countries have incorporated it into their national energy plans. The combination of climate targets, energy security priorities, technology improvement, and industrial competitiveness concerns has solidified hydrogen as an indispensable part of Europe’s future energy mix.

Sector Size and Projections

Market size projections highlight both the uncertainty and the enormous potential of this sector. A conservative projection conducted by BlueWeave estimates a 2025 European green hydrogen market size of $415.89 million with a compound annual growth rate of 47.95% that would push the market to $20.90 billion by 2035. This estimate reflects moderate scaling of electrolyzer deployment and restrained assumptions regarding cost declines and offtake formation. It also assumes that competition from cheaper production regions outside Europe will keep some European production costs relatively high through the end of the decade.

A more optimistic assessment from ResearchAndMarkets places the 2025 market at $705.58 million and projects a compound annual growth rate of 66.7%, resulting in a 2035 market size of $116.71 billion. This scenario reflects stronger policy implementation, more rapid cost declines, and an accelerating build out of renewable energy capacity. It also assumes that green hydrogen adoption in heavy industries will scale quickly once enabling infrastructure is in place and once companies begin purchasing substantial volumes of green feedstocks to meet corporate decarbonization targets.

The third scenario, which comes from TCM, offers the most aggressive projection. It estimates that the European market will reach $6.83 billion in 2025 and rise to $208.13 billion by 2035 with a compound annual growth rate of 40.74%. This projection assumes that hydrogen will become one of the core energy commodities of the European industrial economy. It assumes extremely rapid electrolyzer deployment, strong improvement in costs, large scale infrastructure investment, and widespread adoption of green hydrogen based fuels in transportation, refining, and chemicals.

Together, these projections illustrate a market that is not only growing but also fundamentally transforming. Even the most conservative estimate implies a fifty fold expansion over ten years. In the moderate and advanced cases, green hydrogen becomes a multi hundred billion dollar industry that reshapes European industrial supply chains and creates entirely new value pools in clean fuels, energy storage, and emissions free manufacturing.

Major Countries in Green Hydrogen Production

Green hydrogen deployment within Europe is highly uneven, with a small number of countries emerging as leaders. Germany is currently the largest player with approximately 120 MW of operational electrolyzer capacity. The country has set a target of 10 GW by 2030, supported by major state aid programs and industrial strategies focused on decarbonizing steel, chemicals, and refining. Germany’s development pipeline includes roughly 1.3 GW of low emissions electrolyzer capacity that could come online by 2030. The country’s leadership is driven by strong policy support, high carbon prices, and the presence of large heavy industries that require low carbon fuels.

Spain is rapidly positioning itself as one of the most important long term producers of green hydrogen. Although operational capacity is limited today, Spain accounts for roughly 25% of all planned European electrolyzer capacity for 2030. This is largely due to its lower electricity costs, strong capacity to expand renewables, and abundant land availability. Spain has approved €800 million in subsidies in 2024 and an additional €400 million in 2025 to accelerate large scale project development. These subsidies are directed at GW scale projects that integrate renewable energy with hydrogen production zones, ammonia facilities, and industrial customers.

The Netherlands, although possessing only around 10 MW of operational electrolyzer capacity today, plays a strategically important role in Europe’s hydrogen landscape. The country has set a target of 3-4 GW by 2030 and is currently developing 230 MW of low emissions electrolyzer capacity. More importantly, the Netherlands controls some of Europe’s most critical port infrastructure through Rotterdam and serves as a future hub for hydrogen imports, storage, and pipeline distribution across Northwest Europe.

France represents a high potential, but currently modest deployment story. The country has a national target of 4.5 GW of electrolyzer capacity by 2030 and 8 GW by 2035. National mandates requiring domestic hydrogen use in certain sectors create a favorable policy environment. France has strong industrial players, strong nuclear powered baseload electricity that complements hydrogen production, and ambitious corporate strategies for hydrogen fuel production.

Denmark stands out due to its extraordinary offshore wind potential. The country has set a target of 4-6 GW of electrolyzer capacity by 2030 and already has 240 MW under construction. It is also evaluating plans to construct a green hydrogen island with a total planned capacity of 10 GW, which would position it as one of Europe’s major exporters of green hydrogen derived products.

Technology Development

Green hydrogen production relies on electrolysis, a process that splits water into hydrogen and oxygen using electricity. This technology is not new, but until recently it was not deployed at large scale due to high costs and limited demand. The past decade has seen major improvements in electrolyzer technology, driven by advances in materials science, manufacturing scale, and integration with renewable energy systems.

Three main electrolyzer technologies are used today. Alkaline electrolyzers are the most mature and lowest cost and have been used for decades in industrial applications. However, they are less suited to pairing with intermittent renewables because they respond more slowly to changes in electricity output. Their capital costs are expected to fall significantly from roughly €500-600/kW in 2025 to about €297/kW by 2030. Their levelized cost of hydrogen is expected to fall from a range of €4–6/kg to roughly €2.63/kg by 2030.

Proton exchange membrane (PEM) electrolyzers are the second most mature technology and are better suited to renewables because of their dynamic response capability. They have higher capital costs today, ranging from €700–1000/kW, but these costs are expected to decline to about €315/kW by 2030. The levelized cost of hydrogen for PEM systems is projected to fall from €5–7/kg in 2025 to approximately €2.43/kg in 2030.

Solid oxide electrolysis cell (SOEC) electrolyzers represent an emerging technology. They have the highest efficiency potential but remain at low technology readiness levels. Their capital costs range from €1500–2500/kW today and are projected to fall to about €828/kW by 2030. These systems can achieve high efficiencies due to their high operating temperatures and ability to use waste heat. Their levelized cost of hydrogen may fall from €6–10/kg to approximately €3.07/kg by 2030. If these systems achieve commercial maturity, they could play a major role in industrial hydrogen production.

Future Drivers of Growth

Policy Drivers

Policy is the single most important force shaping the European green hydrogen market. At the European Union level, the EU Hydrogen Strategy sets goals for 2030 of 40 GW of renewable electrolyzer capacity as well as producing 10 Mt of green hydrogen domestically and importing an additional 10 Mt by 2030. This framework provides long term visibility for developers and creates a unified market across the European Union. The Renewable Energy Directive and the REPowerEU package have introduced binding requirements for the use of renewable fuels of non biological origin (RFNBOs) in both industry and transport. These rules require that a certain share of industrial hydrogen consumption must come from renewable sources. They also mandate that maritime and aviation sectors begin using green hydrogen derivatives such as green ammonia, methanol, and synthetic kerosene. These regulations create direct demand obligations that will likely increase over time.

Additional policy push is given by the EU Emissions Trading System (ETS). The emissions cap is scheduled to fall by 4.4% annually, making allowances scarcer and increasing the carbon price. This will place even greater pressure on hard-to-abate sectors to use green hydrogen to lower their emissions. The expansion of the EU ETS in 2027 to include buildings, road transport, and small industry will also generate further demand for low carbon fuels.

Direct financial support is being delivered through the European Hydrogen Bank Innovation Fund Auctions. These auctions provide selected green hydrogen projects with fixed premiums per kg of RFNBO hydrogen for up to ten years. First two rounds of auctions in 2023 and 2024 awarded €720 million and €992 million respectively. A third auction being held at the end of this year will have a budget of up to €1 billion. National state aid programs complement this funding, with Spain, Germany, France, the Netherlands, Italy, Austria, and Lithuania having all introduced their own support schemes using different funding methods. Spain alone approved €800 million in subsidies for green hydrogen projects in 2024 with another €400 million approved in 2025.

Pricing and Commercial Factors

Declining technology costs are a major commercial driver. As mentioned in the Technology Development section, electrolyzer capital costs are predicted to fall due to scaling effects and improved manufacturing. Electricity prices remain the single largest determinant of green hydrogen cost, with electricity typically accounting for 50 to 70% of levelized hydrogen costs. As Europe increases its renewable energy capacity and improves grid interconnection, the cost of producing hydrogen from electrolysis will continue to fall.

Offtake markets are beginning to mature, with green steel being the most advanced commercial application. Stegra, formerly H2 Green Steel, has signed long term supply agreements with major automotive manufacturers including Mercedes Benz, BMW, Scania, and Kirchhoff Automotive as well as an agreement with Microsoft to provide green steel for data center infrastructure. Chemical production and transportation industries are also engaging in green hydrogen offtake. Companies such as Maersk, Yara, Shell, and Repsol have signed agreements for green ammonia and green methanol, which are key fuels for maritime shipping and fertilizer production. These contracts demonstrate that industrial users are willing to pay a premium for low carbon materials, particularly where they face regulatory pressure or corporate climate commitments.

Europe benefits from strong renewable resource potential. Southern Europe has the lowest solar costs in Europe and strong onshore wind resources. Land availability relative to population is high, enabling the construction of large renewable energy complexes. Northern Europe possesses vast offshore wind potential in the North Sea and Baltic Sea. These regions are close to industrial centers and are therefore well positioned for integrated hydrogen production hubs. Several countries are evaluating the creation of energy islands that connect offshore wind farms to electrolyzer facilities and hydrogen transmission networks.

Infrastructure Development

Infrastructure is essential for the creation of a continental hydrogen market and several large projects have been developed to construct this infrastructure. The European Hydrogen Backbone is a coordinated infrastructure blueprint developed by major gas transmission system operators that envisions 31,500 km of hydrogen pipelines constructed by 2030, increasing to 53,000 km by 2040. The network would connect 28 countries and link production zones in Southern and Northern Europe to industrial demand centers in Central and Western Europe, with 60 to 70% of this network being built by repurposing existing natural gas pipelines.

Hy2Infra, a large-scale infrastructure project, has received up to €6.9 billion in state aid from France, Germany, Italy, the Netherlands, Poland, Portugal, and Slovakia. It will finance 3.2 GW of electrolyzer capacity, 2,700 km of pipelines, 370 GWh of hydrogen storage, and new port terminals capable of handling liquid organic hydrogen carriers. This project aims to create continuous hydrogen corridors that reduce price disparity and create transparent market pricing similar to natural gas hubs.

The H2Med project will create two major cross-border hydrogen pipelines with targeted completion dates of 2032. The CelZa project is a 270km pipeline between Portugal and Spain with 0.75 Mt per year capacity. The BarMar project is a 400–450 km offshore hydrogen pipeline linking Spain and France with a 2 Mt per year capacity. These pipelines will transport green hydrogen from production sites in Southern Europe and into Central European industrial networks. The project aims to transport 10% of the European Union’s 2030 hydrogen target volume and establish the Iberian Peninsula as a major export hub.

Hydrogen storage is a critical component of the future system. Salt caverns are considered the best option because they allow for large volumes, low leakage, and rapid cycling. Several storage projects are under way including Hystock in the Netherlands and Underground Sun Storage 2030 in Austria. There is also ongoing research regarding the potential use of depleted natural gas fields, though performance limitations remain.

Barriers and Headwinds

Despite strong policy momentum, the sector faces significant barriers. Green hydrogen remains expensive, with green hydrogen being 1.5-3x more expensive than fossil-fuel based hydrogen due to electricity costs and higher CAPEX. The lower cost of renewable energy in Southern Europe can make green hydrogen more competitive in that region, but continued high costs in Central and Northern Europe pose challenges. Projections on green hydrogen CAPEX and renewable electricity costs are optimistic, but if they do not manifest as readily as expected many projects could find themselves at risk. The offtake market, while growing, remains thin. Many large projects rely on non-binding memoranda of understanding rather than firm purchase agreements, which creates significant revenue risk for developers. Delays are also a frequent occurrence with major projects like Iberdrola in Spain and Salzgitter in Germany being delayed pending Hydrogen Bank subsidies and long-term offtake agreements.

Technological and infrastructure challenges persist. Electrolyzer technologies have limited long term field data and uncertainties remain about degradation rates. Electrolyzer technologies with higher efficiency and better suitability for renewables have higher CAPEX, increasing initial investment costs. PEM systems rely on platinum group metals which are rarer and more expensive. Hydrogen pipelines are currently limited, with about 1,636 km of complete pipelines. Pipeline conversion requires testing for hydrogen embrittlement, re-coating, and substantial replacement of compressors, valves, and meters. Blending limits also vary widely (5–20%), and no harmonized EU technical standard exists. Existing hydrogen storage capacity is also limited, with 9 TWh of storage currently under development. However, this is significantly lagging behind the 36 TWh needed for the 20 Mt goal. Salt caverns are also geologically limited, being located primarily in Germany and the Netherlands. The use of depleted gas fields for storage is possible, but additional research is needed to assess feasibility.

Regulatory and political risks remain high as well. Most hydrogen projects are not financially viable without subsidies, and the European Hydrogen Bank auction rounds have been heavily oversubscribed. The first auction received 132 bids and awarded funding to only seven projects. The second auction received 61 bids requesting a total of €4.8 billion, four times the available budget of €1.2 billion. Growing concerns over the rising cost of living in Europe have prompted calls to reduce spending on climate projects which could jeopardize or delay projects. Regulatory complexity and permitting bottlenecks remain major barriers. Strict criteria for RFNBOs regarding additionality and temporal and geographic correlation raises system and CAPEX costs and complicates offtake agreements. Renewable energy and clean tech projects can take over 7 years to get permits, with 83% of companies citing it as a major obstacle to investment. Hydrogen projects therefore face double permitting risk for both renewable energy and hydrogen production facilities, with hydrogen infrastructure projects already facing 2-3 year delays

International competition also poses a challenge, with high electricity costs and regulatory complexity limiting Europe’s competitiveness in the global market. China accounts for 60% of global manufacturing capacity for electrolyzers and produces alkaline electrolyzers 70% cheaper than those of western manufacturers. China and the Middle East offer greater renewables access, lower LCOE, and direct, state-backed support for green hydrogen projects allowing for faster development of large-scale projects like Neom in Saudi Arabia. As a result, the European market runs the risk of becoming an importer of green hydrogen rather than an exporter.

Specific Projects or Business Successes

Stegra in Sweden is one of the most advanced green hydrogen projects in the world. The company is building an integrated steel and hydrogen facility with the goal of producing 5 Mt of green steel annually by 2030. Though still under construction, the company has pre-sold more than 1.5 Mt of green steel to automotive and industrial customers under long term agreements. The company has secured €6.5 billion in financing, consisting of €4.2 billion in project debt, €2.1 billion in equity, and a €250m EU Innovation Fund grant. The company also recently signed an agreement to supply green steel to Microsoft for its data center operations. This company demonstrates the strong potential of integrated green hydrogen and derivative product projects.

The Iberdrola and Fertiberia project in Spain is another major success. The project combines renewable energy with a green hydrogen production facility and ammonia production. The first phase includes a 20 MW PEM electrolyzer powered by 100 MW of solar and 20 MWh of battery storage. The companies plan to scale the electrolyzer capacity to 800 MW by 2027 with a total investment of €1.8 billion.

RWE is developing the GET H2 Nukleus project in Germany. The project will deploy 300 MW of electrolyzer capacity built in stages through 2027 and has already secured a long term supply contract with TotalEnergies for 30,000 t of green hydrogen per year from 2030 to 2044. Shell is also expanding its hydrogen portfolio with the 200 MW Holland Hydrogen I project in Rotterdam and the 100 MW REFHYNE II project in Germany, which are scheduled to be completed in the late 2020s and will provide green hydrogen for Shell refineries.

Lhyfe and OX2 have partnered to develop a green hydrogen industrial cluster in Sweden. The project would connect onshore wind power with green hydrogen production to be used in on-site green ammonia production. While still in the conceptual phase, the project plans an annual wind energy capacity of 1.4 Twh and electrolysis capacity of ~300 MW. HyDeal España is another ambitious project aiming to develop a green hydrogen hub located in Northwest Spain supplying green hydrogen for industrial uses. The original goal included 9.5 GW of solar capacity and 7.4 GW of electrolyzers by 2030, although these targets have been revised down to 4.4 GW of solar capacity and 3.3 GW of electrolyzer capacity by 2031 with first production beginning in 2028. The project has long term offtake agreements with ArcelorMittal and Fertiberia totaling 6.6 Mt over 20 years, which is still in place despite the reduced goal.

AquaVentus and BrintØ are two longer term offshore hydrogen projects in Germany and Denmark. Each project envisions 10 GW of offshore wind coupled with large scale electrolyzers. These projects are in early stages, but demonstrate Europe’s significant green hydrogen goals.

Companies with High Benefit Potential

Several categories of companies are positioned to benefit from green hydrogen growth. Industrial gas and energy corporations such as AirLiquide, Shell, TotalEnergies, Engie, BP, Ørsted, and Repsol stand to gain because they already operate hydrogen infrastructure and serve industries that will transition to low carbon feedstocks. These companies also have large balance sheets that allow them to finance capital intensive projects.

Electrolyzer technology manufacturers such as John Cockerill, thyssenkrupp nucera, Nel ASA, ITM Power, Sunfire, Snam, McPhy Energy, and Siemens Energy will benefit from rising demand for electrolyzer capacity. The European electrolyzer market was valued at $892.4 million in 2024 and is projected to grow to $1.8 billion by 2030 with a compound annual growth rate of 12.4%.

Project developers such as Stegra, Iberdrola, Lhyfe, RWE, DH2 Energy, Gen2 Energy, and Everfuel are building large scale projects. Successful developers will capture significant value from early market leadership, but they also face higher risks due to capital requirements and uncertain revenue streams.

Conclusion and Investment Recommendations

The European green hydrogen sector presents a compelling long term investment opportunity. The industry is supported by strong climate policy, a growing set of corporate decarbonization commitments, rapid technological improvement, and major infrastructure plans. Projections for both the green hydrogen market and the European electrolyzer market show strong growth through 2035. Europe’s plans for more than 31,000 kilometers of hydrogen pipelines by 2030 and 53,000 kilometers by 2040 further reinforce long term market development.

However, the short term environment remains challenging. Many publicly traded companies in the hydrogen space have performed poorly. Ørsted has withdrawn from several larger green hydrogen projects to focus on wind energy expansion with green hydrogen as a smaller complementary technology. Thyssenkrupp nucera projects an up to 40% drop in electrolyzer sales for 2026, citing a more challenging hydrogen market. Repsol has significantly reduced its 2030 green hydrogen production targets by up to 63% citing market development delays and regulatory challenges. Delays in subsidy allocation and slow permitting timelines continue to weigh on project execution.

The sector is not yet a “set-and-forget” growth sector, but requires carefully chosen exposures, realistic time horizons, and a willingness to tolerate policy and execution risk. Investment into this market will need to diversify across lower risk integrated utilities and industrial gas companies and higher risk equipment manufacturers and independent project developers.

Lower risk recommendations: Air Liquide, Iberdrola, RWE, and Shell. Air Liquide is one of the world’s largest incumbent hydrogen producers, and recently finalized a decision on development of a 200 MW electrolyzer project in the Netherlands. Iberdrola is a global leader in renewable energy systems whose main green hydrogen project has a built in offtaker, operational production capacity, and additional capacity under construction. RWE is a large integrated utility with a strong renewables and gas portfolio. Their green hydrogen project has near complete operational capacity, a signed offtaker agreement, and additional capacity under construction. Shell is a leading gas company with global presence, an existing demonstration project in REFHYNE I, and two larger scale projects under development. These companies have strong balance sheets, existing customer relationships, and operational or near operational hydrogen projects that limit downside risk. 

Higher risk recommendations: thyssenkrupp nucera, Nel ASA, Stegra, and Lhyfe. Thyssenkrupp nucera is one of Europe’s leading electrolyzer manufacturers and despite announcing lower sales projections, could provide strong returns if increased demand manifests especially if stocks are purchased while currently low. Nel ASA currently has 1 GW of electrolyzer manufacturing capacity with current expansion into the US market. It also received a €135 million EU Innovation Fund grant to expand production. Stegra is an integrated green hydrogen and steel production project with significant existing investment and strong offtaker agreements. Lhyfe is a project developer with successful pilot projects with a planned large scale project with an integrated renewable energy source and industrial offtaker. This selection includes electrolyzer manufacturers who stand to benefit significantly from rising electrolyzer demand and offers exposure to green hydrogen production projects with higher permitting and capital risks, but significant returns if successful.

In summary, the European green hydrogen market is on a clear long term growth trajectory. While near term volatility and uncertainty remain, the sector is becoming an integral part of Europe’s industrial and energy future. Investors who take a strategic, diversified approach will be best positioned to capture value as the market expands through the next decade.
