Global Green Hydrogen Market Outlook, 2031

The global green hydrogen market is at a critical inflection point, transitioning from pilot-scale demonstration to commercial-scale deployment as electrolyzer costs decline, renewable energy costs fall, and policy support strengthens across major economies. Global hydrogen demand continues to rise, with demand still almost exclusively from established sectors including refining, ammonia, methanol, and fossil-based direct reduced iron. Low-emissions hydrogen use has increased but remains a very small fraction of total demand due to cost challenges and insufficient policy support. The scale of electrolyser projects is growing rapidly, with large-scale projects commissioned in China and Saudi Arabia's NEOM project targeting multi-gigawatt capacity, representing an unprecedented increase in deployment scale over just a few years. Capital spending on low-emissions hydrogen projects has risen sharply, with spending potentially rising further in 2025. The competitive landscape features a mix of global and regional players, with major companies including Siemens Energy, Nel ASA, ITM Power, Plug Power, Air Liquide, and ThyssenKrupp Nucera leading the market, alongside Chinese manufacturers including Sungrow and Trina Green Hydrogen.

The global development of green hydrogen exhibits significant regional imbalances, with Asia-Pacific emerging as the dominant force as China accounts for approximately half of global green hydrogen capacity. China is set to dominate the green hydrogen market, with energy analysts projecting the country will produce 33.4 million metric tons of zero-emission electrolytic hydrogen in 2050, compared to 4.7 MMt in the US and 20 MMt in the European Union. Europe holds the largest share of the global hydrogen electrolyzer market, driven by strong regulatory support, large-scale industrial decarbonization programs, and aggressive net-zero targets, with Germany, the Netherlands, Italy, Denmark, and Finland leading deployment. North America is driven by the cost pressures of reducing emissions in hard-to-abate sectors, with the United States representing a substantial market, though a Presidential Memorandum in 2025 withdrew offshore wind leasing areas, creating policy uncertainty. Global installed electrolyser capacity continues to expand, with year-on-year growth remaining strong. The market is witnessing a transition from single-component supply to integrated modular systems, with digitalization, predictive maintenance, and advanced materials enabling significant efficiency gains. Key obstacles include high production costs, demand and regulatory uncertainty, infrastructure gaps, and the significant cost gap between low-emissions hydrogen and conventional fossil-based alternatives.

Market Dynamics

Market Drivers • Decarbonization of Hard-to-Abate Sectors: The most powerful driver across the global green hydrogen market is the imperative to decarbonize industries where direct electrification is not feasible, including refining, ammonia production, methanol production, and steel manufacturing. Demand is still almost exclusively from established sectors including refining, ammonia, methanol and fossil-based direct reduced iron, with demand for new applications growing but from a very low base. Refining and the chemical sector lead the way in the adoption of low-emissions hydrogen, with more than 2 Mtpa expected to be consumed in refineries and industrial facilities by 2030 based on projects that are operational, under construction or have reached final investment decision. Ammonia is projected to dominate international flows, with 30% of global demand expected to cross borders, followed by e-methanol at 18% and direct reduced iron at 14%.
• Falling Renewable Electricity Costs and Policy Support: The dramatic decline in solar and wind costs has made green hydrogen increasingly cost-competitive, particularly in regions with excellent renewable resources. Regions with a high penetration of renewable energy, especially Europe, consistently achieve a lower levelized cost of hydrogen, while Asia, where the adoption of renewable technologies is relatively slow, exhibits higher costs. The cost-effectiveness of green hydrogen is strongly contingent upon the accessibility and affordability of renewable energy resources, with regions abundant in solar and wind potential, such as Africa, Australia, and certain parts of South America, better positioned to realise lower production costs. Strategic policy interventions could unlock substantial demand in the near term, with key opportunities including focusing on existing hydrogen uses where technology barriers are lower, leveraging public procurement power, and implementing holistic policy frameworks that incorporate offtake requirements.

Market Challenges • High Production Costs and Demand Uncertainty: The significant cost gap between low-emissions hydrogen and conventional fossil-based alternatives remains the primary barrier to scale-up, in both traditional applications like refining and emerging applications such as steel, shipping and aviation. Uncertain demand continues to pose a critical challenge to the industry's viability, with cumulative firm offtake agreements covering only a small fraction of the potential production that announced projects could achieve by 2030. Offtake momentum slowed in 2024, with signed deals covering less than in the previous year, only 20% of which were firm agreements.
• Infrastructure Gaps and Financing Constraints: The lack of hydrogen storage and transportation infrastructure is a major constraint, particularly for exporting green hydrogen from low-cost production regions to demand centers. A small share of announced hydrogen projects worldwide have secured committed investments, with an even smaller share in emerging economies, with only 5% of projects in these regions showing moderate potential for 2030 operation. Emerging economies face significant challenges in turning hydrogen ambitions into timely deployment, despite abundant renewable energy potential and competitive labour costs.



Market Trends • Scaling of Electrolyzer Manufacturing and Technology Diversification: Electrolyzer manufacturing capacity is expanding rapidly, with giga-scale factories being built in Europe, China, and the United States, driving cost reductions through economies of scale. The hydrogen electrolyzer market is characterized by a moderately consolidated structure, with the alkaline electrolyzer segment leading, followed by PEM electrolyzers, and solid oxide electrolyzers. The solid oxide segment is emerging as the fastest growing, driven by its superior efficiency, high-temperature operation, and ability to utilize industrial waste heat. Technology development is accelerating at unprecedented speed, with more technologies advancing in readiness levels than in any previous year, particularly in steel, shipping, and aviation applications.
• Green Ammonia and Methanol as First Large-Scale Applications: Green ammonia and methanol are emerging as the first large-scale applications for green hydrogen, leveraging existing ammonia and methanol markets and infrastructure. Ammonia production for fertilizers and chemicals, methanol production for plastics and chemicals, and oil refining are vital for decarbonizing incumbent uses. In Southeast Asia, nearly half of all hydrogen demand is for ammonia, of which two-thirds comes from Indonesia alone, with refining accounting for a third of demand and methanol representing the remaining 20%. Power-to-X products such as green methanol and ammonia facilitate the synthesis of carbon-neutral fuels, significantly reducing emissions in hydrogen and carbon-dependent industrial sectors.
