Market Segmentation Analysis
By Technology
Steam Methane Reforming holds the largest market share due to established infrastructure and lower production cost compared to other routes. Industrial users prefer this method for large-scale hydrogen output and high conversion efficiency. Coal gasification remains relevant in regions with abundant coal reserves, supporting cost-sensitive industries. However, cleaner routes such as electrolysis gain momentum with rising renewable energy integration and emission mandates. Governments promote green hydrogen incentives, which encourage industries to shift toward water electrolysis and hybrid renewable systems. Technology advancements and declining renewable power tariffs continue to reduce operational costs, making alternative routes more viable over time.
- For instance, Grasys has developed hydrogen generation units by steam methane reforming that produce up to 130,000 m³/hour of hydrogen with a purity of up to 99.999%.
By Application
Ammonia production dominates the application segment with the highest market share, driven by strong fertilizer demand and industrial feedstock usage. Refineries and petrochemical plants integrate hydrogen for desulfurization and fuel upgrading, supporting petroleum refining as another major segment. Methanol and transportation applications expand with cleaner fuel adoption and hydrogen-based mobility initiatives. Power generation and industrial heating gain traction as industries target lower emissions and energy security. Many countries invest in hydrogen-ready turbines, pipelines, and storage to support long-term decarbonization strategies. Government programs and corporate sustainability targets accelerate hydrogen adoption across new end-use sectors.
- For instance, thyssenkrupp Uhde offers modular green-ammonia plants in capacity classes ranging from 50 metric tons per day (tpd) up to 5000 tpd.
By Systems
Captive systems account for the dominant market share as large industrial facilities generate hydrogen on-site to ensure steady supply and lower logistics cost. These systems support ammonia producers, refineries, and chemical factories with continuous high-volume demand. Merchant systems grow at a faster pace due to rising distributed applications, urban fueling stations, and temporary industrial usage. Expanding hydrogen transport networks, liquid carriers, and tube trailers strengthen merchant business models. Growing investment in electrolyzer parks and green hydrogen hubs encourages partnerships between producers and utilities, expanding supply availability for diverse commercial customers.
Key Growth Drivers
Decarbonization Policies and Net-Zero Targets
Governments push strict emission rules across heavy industries. Many countries plan net-zero targets and promote green hydrogen. Electrolysis supports clean production because it uses water and renewable power. Steel, cement, and chemical plants adopt hydrogen to replace carbon-heavy fuels. Policy incentives reduce risk for new projects and lower adoption cost. Subsidies support electrolyzer purchases and renewable electricity use. Public funding accelerates pilot plants, fuel-cell mobility, and hydrogen hubs. Large buyers sign long-term contracts, which help investors. Strong climate commitments from multinational companies create stable demand. As a result, green hydrogen becomes a strategic pillar for long-term climate goals and industrial transformation.
- For instance, under India’s National Green Hydrogen Mission, contracts have been awarded for 3,000 MW per annum of electrolyser manufacturing capacity and for green hydrogen production capacity of 412,000 tons per annum.
Falling Renewable Energy Costs and Grid Expansion
Solar and wind prices decline due to large-scale manufacturing and strong installation growth. Lower electricity cost improves the economics of electrolysis. New high-voltage power lines help move clean energy from remote sites. Grid operators support flexible demand programs that suit hydrogen production. Large renewable farms build co-located hydrogen plants to avoid curtailment. Companies sign power purchase agreements to guarantee steady input power. These steps increase system efficiency and plant runtime. More nations expand charging, storage, and backup systems that support hydrogen clusters. As renewable energy becomes cheaper, green hydrogen moves closer to cost parity with fossil-based hydrogen.
- For instance, in India the utility-scale solar plant levelised cost of electricity (LCOE) reached US $0.038 per kWh in 2024.
Fuel-Cell Transportation and Industrial Applications
Hydrogen fuel-cell vehicles attract attention for long driving range and fast refueling. Heavy trucks, buses, trains, and ships benefit from hydrogen because batteries add weight. Countries invest in fueling stations and truck corridors. Aviation and shipping firms explore hydrogen-based fuels to cut emissions. Factories use hydrogen for high-temperature heat and power. Refineries adopt clean hydrogen for desulfurization. Long-duration energy storage becomes a new growth route. These uses create strong commercial demand. As adoption rises in transport and industry, scale improves supply chains and lowers cost, supporting faster market expansion.
Key Trend & Opportunity
High-Capacity Electrolyzers and Modular Plants
Manufacturers design large electrolyzers with higher efficiency and easier maintenance. Modular designs allow quick deployment in remote areas. New stacks improve durability and reduce water use. Developers build 100-megawatt and gigawatt plants linked to wind and solar farms. Many countries create hydrogen valleys that combine production, storage, and end-use. Standardization reduces project risk and speeds approvals. Partnerships between utilities and industrial buyers secure long-term revenue. These innovations lower cost per kilogram and make hydrogen more competitive. As plants get larger, supply becomes reliable and supports major industries such as steel and fertilizers.
- For instance, Accelera (a division of Cummins Inc.) will supply a 100 MW PEM electrolyzer system for bp plc’s Lingen green hydrogen project in Germany; the system is expected to produce up to 11,000 tons of green hydrogen per year.
Hydrogen Infrastructure and Export Trade
Nations invest in pipelines, storage caverns, port terminals, and liquefaction sites. Infrastructure growth improves supply flexibility and lowers transport cost. Europe, Japan, and South Korea plan large import contracts. Middle East and Australia develop mega-export hubs linked to renewable resources. Green ammonia becomes a common carrier for overseas shipping. Shipping firms test liquid hydrogen and compressed gas solutions. Standard safety codes help operators expand networks safely. Trade creates new business models and long-term price stability. Global demand encourages continuous investment, making hydrogen a global commodity.
- For instance, Plug Power Inc. delivered 44.5 metric tons of renewable hydrogen to the H2CAST salt-cavern storage project in Germany between April and August 2025.
Key Challenge
High Capital Cost and Limited Commercial Scale
Electrolyzers and renewable power systems need large upfront investment. Smaller plants face high unit costs and struggle to compete with fossil hydrogen. Long permitting cycles delay project timelines. Developers need strong financing and power purchase agreements. Some regions lack stable policies and risk long-term planning. Without scale, supply chains remain slow and expensive. Many companies wait for cost parity before switching. These issues slow market growth and limit adoption in cost-sensitive industries. Continuous subsidies, technology improvements, and larger production orders will ease this challenge.
- Infrastructure Gaps and Storage Complexity
Hydrogen is light and requires compression, liquefaction, or conversion for transport. Pipelines and fueling stations remain limited in many regions. Storage tanks need advanced materials and strict safety rules. Distribution equipment adds cost for refineries, factories, and transport operators. Without broad networks, buyers cannot rely on steady supply. Fueling shortages discourage vehicle adoption. Long-term storage needs geological caverns or advanced systems that remain expensive. These hurdles delay commercial expansion. Coordinated planning, public investment, and clear standards will help solve infrastructure gaps and support reliable market growth.
