Alkaline systems generally use nickel-based electrodes, reducing their dependence on expensive precious metals such as platinum and iridium.
A 2024 delivery analysis indicated that alkaline systems represented approximately 2.7 GW of the 3.2 GW of electrolyzers shipped globally, accounting for nearly 84% of total deliveries. John Cockerill also reported that alkaline technologies usually represent between 70% and 90% of annual global electrolyzer shipments. Comparable PEM systems can cost approximately 15% to 30% more, strengthening the attractiveness of alkaline systems for large industrial facilities.
The segment also benefits from a large installed base across fertilizer production, petroleum refining, steel manufacturing, and chemical processing. According to the World Bank, global operational electrolyzer capacity reached nearly 2.15 GW by mid-2025, with alkaline systems representing the majority. China received approximately 1.44 GW of the 3.2 GW shipped globally in 2024, with most projects relying on alkaline technology.
Delivery Form Analysis
Compressed Gas Hydrogen Leads with a 51.2% Market Share
In 2025, compressed gas hydrogen captured a dominant 51.2% share of the clean hydrogen market. Its leadership was supported by compatibility with existing transportation, industrial, and refueling infrastructure. Compressed hydrogen is commonly stored at pressures ranging from 350 to 700 bar, making it one of the most widely adopted hydrogen delivery methods.
Unlike liquid hydrogen, compressed gas does not require cryogenic cooling or additional chemical conversion. This reduces energy consumption, operating complexity, and infrastructure costs. According to H2stations, approximately 980 hydrogen refueling stations were operating globally by the end of 2024, with most dispensing hydrogen at either 350 or 700 bar. Compressed gas stations also accounted for approximately 72% of global hydrogen fueling station revenue in 2025.
The segment benefits from established industrial distribution systems. High-pressure tube trailers can transport up to 1,100 kg of hydrogen per load at pressures of around 500 bar. These systems are widely used by chemical facilities, glass producers, food processors, and other industrial users without access to hydrogen pipelines. Established logistics and lower infrastructure requirements are expected to maintain the segment’s leading position.
Application Analysis
Transportation Holds a 26.5% Market Share
In 2025, transportation accounted for a major 26.5% share of the clean hydrogen market. Growth was supported by the increasing deployment of fuel cell vehicles, hydrogen-powered buses, heavy-duty trucks, and expanding refueling infrastructure. According to the IEA Advanced Fuel Cells Technology Collaboration Programme, the global fuel cell vehicle fleet reached approximately 97,356 units by the end of 2024.
The fleet was supported by around 1,302 hydrogen refueling stations across 28 countries. Passenger fuel cell vehicles typically consume between 1 and 5 kg of hydrogen per refueling, while heavy-duty fuel cell trucks can require between 30 and 80 kg per fill. The expansion of these vehicle fleets is directly increasing clean hydrogen consumption.
Heavy-duty transportation remains an important growth area because long-haul trucks account for nearly 26% of global road transport carbon dioxide emissions. China had more than 5,600 hydrogen fuel cell buses in operation, supporting large-scale hydrogen demand. South Korea also allocated KRW 576.2 billion, equivalent to approximately USD 420 million, in 2026 to support the deployment of 7,820 hydrogen vehicles, including 1,800 hydrogen buses. Expanding transport corridors, government incentives, and refueling networks are expected to strengthen the segment’s long-term growth.

Regional Analysis
North America Leads with a 34.5% Market Share
In 2025, North America held the largest share of the global clean hydrogen market, accounting for 34.5%. The region’s leadership was supported by strong government policies, rising investment in hydrogen infrastructure, and the presence of major clean energy and hydrogen technology companies. Financial incentives, tax credits, and decarbonization programs in the United States and Canada further encouraged low-carbon hydrogen production and industrial adoption.
Top Use Cases
1. Oil Refining: Clean hydrogen can replace fossil-based hydrogen used to remove sulfur and other impurities from crude oil during refining. Global hydrogen demand exceeded 100 million tonnes in 2025, with refining and industrial activities accounting for almost all consumption. Replacing conventional hydrogen in existing refineries offers one of the quickest routes for developing stable demand because the required processing systems and technical expertise are already available.
2. Ammonia and Fertilizer Production: Ammonia manufacturing is a major hydrogen-consuming industry because hydrogen is combined with nitrogen to produce ammonia, which is mainly used in fertilizers. Ammonia and methanol together represent roughly 50% of global hydrogen consumption. Clean hydrogen can reduce the natural gas use and carbon emissions associated with conventional ammonia production while supporting the development of low-carbon fertilizers. The opportunity is particularly visible in Southeast Asia, where hydrogen demand reached approximately 4 million tonnes per year in 2024. Nearly half of this demand came from ammonia production, while around 80% of regional hydrogen supply was produced from unabated natural gas.
3. Maritime Shipping: Clean hydrogen can support shipping through direct fuel-cell use or hydrogen-derived fuels such as green ammonia and e-methanol. These fuels are being considered for container ships, bulk carriers and other vessels where direct battery electrification is difficult because of long routes and high energy requirements. As of June 2025, more than 60 methanol-powered vessels were operating globally, while nearly 300 additional vessels were on order. Around 17 ports currently handle more than 60% of global marine fuel demand, creating concentrated locations where hydrogen-based bunkering infrastructure can be developed. Nearly 80 ports already have strong chemical-handling capabilities, making them potential early hubs for hydrogen-derived marine fuels.
4. Methanol and Chemical Manufacturing: Hydrogen is used as an industrial feedstock for methanol, solvents, polymers and several other chemical products. Clean hydrogen can reduce emissions from chemical facilities without requiring manufacturers to completely replace their production processes. The Middle East accounts for close to 17% of global methanol production and approximately 45% of global methanol trade, showing the scale of hydrogen-linked chemical supply chains. Clean hydrogen projects located near chemical clusters and ports can serve existing demand while supporting exports of low-emission methanol and related products.
5. Power Generation and Long-Duration Storage: Clean hydrogen can store excess renewable electricity produced during periods of strong solar or wind generation. The hydrogen can later be used in fuel cells, turbines or industrial facilities when electricity demand rises. This makes it suitable for long-duration and seasonal energy storage, where conventional batteries may become costly. The U.S. Department of Energy identifies hydrogen as a potential solution for firm power generation, industrial heat, natural gas replacement and long-duration energy storage. Global water-electrolysis capacity exceeded 4 GW in 2025, after doubling during the year, while more than 2.5 GW of additional capacity was under construction for planned operation in 2026. This growing electrolyzer base is strengthening hydrogen’s role in renewable power integration.
Conclusion
The clean hydrogen market is moving from early development toward wider industrial adoption, supported by government policies, renewable energy expansion and investment in electrolyzers, storage and transport infrastructure. According to the IEA, global hydrogen demand reached nearly 100 million tonnes in 2024, while low-emissions hydrogen represented less than 1% of total production. However, more than 200 low-emissions hydrogen projects have reached final investment decisions since 2020, and committed projects could raise production capacity to 4.2 million tonnes annually by 2030.
Clean hydrogen is expected to gain stronger use in refining, fertilizer production, steel manufacturing, shipping and heavy-duty transportation. Nevertheless, high production costs, limited infrastructure, uncertain demand and slow regulatory implementation remain important market barriers. Continued cost reductions, firm purchasing agreements and supportive policies will be essential for converting announced projects into commercial operations and establishing clean hydrogen as a reliable part of the global low-carbon energy system.
