Key Industry Players

The market is led by established industrial gas and energy companies, with a few electrolyzer specialists alongside them. The report profiles these companies:

• Air Liquide International S.A.
• Air Products and Chemicals, Inc.
• Cummins Inc. (Hydrogenics)
• INOX Air Products Ltd.
• Iwatani Corporation
• Linde plc
• Matheson Tri-Gas, Inc.
• Messer Group GmbH
• Nel ASA (NEL Hydrogen)
• Taiyo Nippon Sanso Corporation

Air Liquide, founded in 1902 and based in France, covers the whole hydrogen value chain, from large-scale production and purification to storage and distribution. It supplies refining, chemicals, electronics and mobility customers, and is building out low-carbon and green hydrogen through electrolysis and carbon capture.

Linde plc is one of the world's largest hydrogen producers. Its expertise spans steam methane reforming, autothermal reforming, water electrolysis, and hydrogen liquefaction and storage.

A recent development to watch is Air Products' progress in September 2025 on construction milestones at the NEOM Green Hydrogen Project in Saudi Arabia. It is among the largest green hydrogen facilities in the world, pairing large-scale renewable power with electrolysis to produce green ammonia for export.

How the market is segmented

• By technology: coal gasification, steam methane reforming and others
• By system: merchant (transportation) and captive (on-site consumption)
• By application: methanol production, ammonia production, petroleum refinery, transportation, power generation, industrial heating and others
• By region: North America, Europe, Asia Pacific, Latin America, and Middle East & Africa

What the segments show

Technology. Coal gasification is a mature process that has been used for nearly two centuries, and it still leads on revenue. Countries with large domestic coal resources, such as the U.S., see it as a way to reduce reliance on imported petroleum products in transport.

Systems. Captive generation dominates because refining, chemicals and steel operations need a continuous hydrogen supply. Producing it on-site removes the need for external transport and distribution infrastructure.

Applications. Ammonia production remains the largest application. Hydrogen is typically made at the plant from natural gas via steam methane reforming, and ammonia's role as a hydrogen carrier and energy storage medium opens a path for renewable hydrogen at scale. Transportation is expected to be the fastest-growing application, driven by alternative-fuel vehicles, clean mobility infrastructure and supportive policy.

Growth drivers

• Government incentives and subsidies aimed at cutting carbon emissions
• Advances in electrolysis using renewable energy, fuel cells and carbon capture
• Rising demand for green hydrogen in refineries, chemicals and fuel cell applications
• Investment in storage, pipelines and refueling infrastructure

Challenges

• High production costs, especially for green hydrogen
• Limited storage and transport infrastructure
• Technical inefficiencies and inconsistent regulations
• Competition from other renewable energy options

Regional snapshot

• Asia Pacific leads on rapid industrialization, expanding refining and chemical sectors, and strong policy support in China, Japan, South Korea and India.
• North America is growing steadily, with the U.S. benefiting from established infrastructure and hydrogen hub programs.
• Europe is seeing rapid adoption, supported by European Commission-backed fuel cell and hydrogen initiatives.
• Latin America is the fastest-growing region, fueled by infrastructure investment and industrial development.
• Middle East & Africa is emerging as a future hydrogen production and export hub, led by Saudi Arabia and the UAE.

The Outlook

Hydrogen generation is balancing two realities. Today's volumes still depend heavily on established, fossil-based processes, while investment and innovation are steadily moving toward cleaner production. Companies that can scale low-carbon hydrogen cost-effectively, particularly in fast-growing regions and mobility applications, will be best placed through 2033.
