Key Trends in the Green Hydrogen Market

• Rising Decarbonization Goals and Climate Policies: Governments worldwide are setting stringent climate targets to reduce carbon emissions, with green hydrogen identified as a critical tool to achieve these goals. Transport accounts for approximately 23% of annual greenhouse gas emissions globally, with inland transport responsible for 72% of that share. In February 2024, UN Member States adopted the Inland Transport Committee's Strategy for reducing GHG emissions from inland transport, with passenger transport demand projected to increase by 79% and freight transport by 100% by 2050, creating a long-term structural driver for clean fuel solutions including green hydrogen.
  
  
  


• Advances in Renewable Energy and Electrolysis Technology: The cost of renewable energy continues to fall globally, making green hydrogen production through water electrolysis increasingly economically viable. According to the International Energy Agency, in 2023, 96% of new utility-scale solar PV and offshore wind generation capacity added was cheaper than equivalent new coal or natural gas plants. Advancements in electrolysis technologies are simultaneously improving energy efficiency and cutting production costs, enhancing the commercial competitiveness of green hydrogen at scale.
  
  
  


• Growing Industrial and Transport Sector Demand for Clean Energy: Hard-to-decarbonize sectors such as heavy industry, including steel, cement, and chemical production, and heavy transport including shipping, aviation, and long-haul trucking, are increasingly turning to green hydrogen as a sustainable fossil fuel alternative. Transportation sector emissions in the United States increased by 1.6% in 2023 relative to 2022, intensifying the urgency for clean substitutes. Volvo Trucks announced plans in May 2024 to develop trucks with combustion engines running on hydrogen, with on-road tests scheduled to begin in 2026 and commercial launch targeted by the end of the decade.
  
  
  


• Strong Policy and Financial Backing Across Key Regions: Europe's Hydrogen Strategy, the EU Emissions Trading System, and funding programs under Horizon Europe and NextGenerationEU are accelerating electrolyzer deployment and hydrogen infrastructure development. International public finance for low-emissions hydrogen in emerging and developing economies grew from negligible levels in 2022 to approximately USD 3.3 billion in cumulative government commitments by Q1 2026, demonstrating rapid scaling of institutional capital into the sector.
  
  
  


• Expanding Export Ambitions and Cross-Border Hydrogen Trade: Nations with abundant renewable energy potential, such as Australia, Chile, and Saudi Arabia, are positioning themselves as global green hydrogen exporters. In February 2026, Greenzo Energy India Limited and Lord's Mark Industries Limited signed an MoU to co-establish green hydrogen and renewable energy projects across Uttar Pradesh, reflecting the deepening penetration of green hydrogen investment into emerging markets. By Q1 2026, project-level international public finance had reached approximately USD 650 million cumulatively, primarily for project preparation and reducing financing costs.
  
  
  

Growth Factors in the Green Hydrogen Market

• Falling Electrolyzer and Renewable Energy Costs: As renewable energy becomes the cheapest source of new power generation globally, the cost of producing green hydrogen through electrolysis is declining substantially. Alkaline electrolyzers, which dominate the market due to their mature technology, cost-effectiveness, and long operational lifespan, are witnessing improved commercial viability at scale. In March 2024, Greenzo Energy India Limited launched India's first 1 MW Alkaline Electrolyser, a landmark development in the country's green hydrogen infrastructure journey.
  
  
  


• Government Incentives and National Hydrogen Strategies: Policy frameworks including the U.S. Inflation Reduction Act, India's National Green Hydrogen Mission, and the EU's Fit for 55 package are providing critical financial and regulatory support to accelerate green hydrogen adoption. The UK government committed approximately USD 2.19 billion to expand green hydrogen production, with advance funding of approximately USD 438.2 million earmarked for developing 125 MW of green hydrogen capacity in the initial three-year phase, serving multiple industrial sectors.
  
  
  


• Accelerating Industrial Decarbonization Demands: In 2025, on-site generation dominated the green hydrogen distribution channel with a 46% market share, reflecting growing industrial demand for localized clean hydrogen supply. Sectors including steel manufacturing, ammonia production, and chemical refining are seeking green hydrogen as a viable pathway to meet net-zero commitments, with hard-to-abate industries across Asia Pacific, Europe, and North America driving a significant portion of project pipelines.
  
  
  


• Investment Surge and Strategic Partnerships Among Key Players: In October 2025, Plug Power delivered the first of ten 10-megawatt electrolyzer modules for Galp's 100-megawatt green hydrogen project at the Sines Refinery in Portugal. The completed facility is expected to produce 15,000 tonnes per year of renewable hydrogen by early 2026, replace approximately 20% of the refinery's grey hydrogen demand, and reduce Scope 1 and 2 greenhouse gas emissions by 110,000 tonnes of CO2-equivalent annually.
  
  
  


• India's Renewable Energy Surge Supporting Green Hydrogen Scale-Up: India added a record renewable energy capacity of 18.48 GW in 2023-24 according to the Ministry of New and Renewable Energy, creating a strong foundation for cost-competitive green hydrogen production through electrolysis. India's National Green Hydrogen Mission targets the production of at least 5 million metric tonnes of green hydrogen annually by 2030, which is expected to attract over USD 100 billion in investments and generate approximately 600,000 jobs across the value chain.
