Green hydrogen is hydrogen gas produced via electrolysis of water using electricity from renewable sources like solar, wind, or hydropower, resulting in zero or near-zero greenhouse gas emissions throughout its lifecycle, unlike grey hydrogen derived from fossil fuels.
Green Hydrogen Market Size and Share
The Green Hydrogen Market is projected to grow from US$ 8.38 billion in 2024 to US$ 71.31 billion by 2031, registering a robust CAGR of 37.8% during the forecast period. Green hydrogen, produced through electrolysis using renewable electricity, is emerging as a cornerstone in global clean energy transitions, supporting net-zero ambitions and reducing reliance on fossil fuels. The market is witnessing rapid expansion, driven by growing investments in renewable energy, strong government support for decarbonization, and increasing adoption of hydrogen-based technologies across industries.
Market Drivers and Opportunities
The increasing adoption of fuel cell electric vehicles (FCEVs) is a key growth driver for the green hydrogen market. As countries aim to decarbonize the transportation sector, hydrogen-powered mobility solutions are gaining momentum, particularly for heavy-duty vehicles, buses, and long-haul transport. The rising deployment of FCEVs directly stimulates demand for green hydrogen as a sustainable fuel source, encouraging investments in hydrogen production and refueling infrastructure.
Another major opportunity lies in the establishment of large-scale green hydrogen plants. Public–private partnerships and international collaborations are enabling the development of hydrogen hubs and liquefaction facilities, particularly in renewable-rich regions. Such infrastructure expansion improves production capacity, reduces supply chain constraints, and supports hydrogen exports, opening new revenue streams for market participants.
Technology and Application Insights
Technological advancements in electrolysis are central to the growth of the green hydrogen market. Improvements in electrolyzer efficiency, catalyst materials, and system durability are reducing production costs and enhancing scalability. Among production technologies, alkaline electrolysis currently holds a larger market share due to its maturity and cost-effectiveness, while PEM electrolysis is gaining traction owing to its flexibility and suitability for intermittent renewable energy sources.
In terms of renewable inputs, solar energy dominates the market, supported by declining solar power costs and increasing solar installations worldwide. Wind energy is also emerging as a key contributor, particularly in offshore wind-rich regions. From an end-use perspective, the power sector leads green hydrogen adoption, followed by chemical, petrochemical, medical, and food & beverages industries. Green hydrogen is increasingly used for power storage, grid balancing, ammonia production, refining processes, and as a clean feedstock in chemical manufacturing.
