Market Segmentation Analysis:
By Process
Steam reforming dominated the onsite hydrogen generator market in 2024, accounting for more than 55% share. Its leadership is driven by cost efficiency, established infrastructure, and ability to generate hydrogen at scale for industrial applications. This process remains widely adopted in refineries and chemical plants where natural gas availability is strong. Electrolysis follows as a fast-growing segment, supported by rising demand for green hydrogen and integration with renewable energy. While steam reforming holds the largest base, electrolysis is projected to gain share due to global decarbonization efforts and increasing government incentives for clean hydrogen production.
- For instance, Mahler AGS offers its HYDROFORM-M steam reforming systems with capacities between 200 and 5,000 Nm³/h, achieving hydrogen purity levels up to 99.9999 vol% after PSA purification, making them suitable for refineries and chemical plants.
By Capacity
The 100–2,000 Nm³/h capacity range led the market with over 50% share in 2024, supported by its suitability for mid-scale industrial and energy applications. This range provides flexibility, balancing cost efficiency with adequate output for sectors such as chemicals, petroleum, and power generation. Smaller units of 100 Nm³/h remain in demand among research facilities and distributed energy projects but serve niche requirements. Large-scale systems above 2,000 Nm³/h are steadily gaining traction as hydrogen demand rises for grid-scale power, steelmaking, and clean fuel production, though adoption is currently limited to advanced economies and large industrial users.
- For instance, MVS Engineering Pvt. Ltd. has deployed on-site hydrogen plants for steel and chemical clients, delivering a continuous supply of hydrogen with purities of up to 99.9998% and at operating pressures of 15 bar.
By Application
Chemical processing held the dominant position in 2024, capturing over 40% share of the onsite hydrogen generator market. Its leadership stems from widespread hydrogen use in ammonia production, methanol synthesis, and other key industrial processes. Petroleum recovery follows as another major application, driven by the demand for hydrogen in refining and desulfurization. The fuel cell segment is expanding rapidly, supported by growth in clean mobility solutions and stationary power systems. While “others” include diverse sectors such as food processing and electronics, large-scale demand from chemical processing ensures it remains the leading application for onsite hydrogen generation.
Key Growth Drivers
Rising Demand for Clean Hydrogen in Industrial Applications
The increasing shift toward clean energy solutions is driving demand for onsite hydrogen generators in industries such as chemicals, refining, and fertilizers. These generators enable efficient and continuous hydrogen supply while reducing dependence on external logistics and large-scale distribution networks. With industries under pressure to cut emissions and adopt sustainable practices, onsite generation offers cost-effective and reliable production. The strong role of hydrogen in ammonia, methanol, and desulfurization processes ensures consistent adoption, strengthening the market outlook across major industrial hubs worldwide.
- For instance, Air Products & Chemicals, Inc. operates onsite hydrogen plants delivering over 3,000 Nm³/h with 99.999% purity to refineries in North America, supporting hydrocracking and desulfurization units that process more than 150,000 barrels per day of crude oil.
Government Incentives and Decarbonization Initiatives
Supportive government policies promoting hydrogen as a clean energy carrier are fueling onsite hydrogen generator adoption. Incentives for green hydrogen production through electrolysis, particularly in Europe, North America, and Asia-Pacific, are accelerating deployment. Carbon reduction targets and renewable integration goals are also encouraging industries to invest in onsite hydrogen solutions. These initiatives not only support technological advancements but also reduce financial barriers for end-users. As global economies pursue net-zero commitments, the availability of favorable regulations and subsidies will remain a critical driver of market growth.
- For instance, Teledyne Energy Systems has deployed electrolysis units producing 5 to 50 Nm³/h of hydrogen at >99.999% purity, supported by U.S. Department of Energy funding programs, enabling industrial users to align with decarbonization and renewable integration targets.
Growth of Hydrogen Fuel Cell Applications
The rapid expansion of hydrogen fuel cell technology in transportation and stationary power generation is creating strong demand for onsite hydrogen generators. Fuel cells require a reliable and high-purity hydrogen supply, which is efficiently supported by localized generation systems. Applications in electric vehicles, buses, forklifts, and backup power are expanding across developed and emerging regions. Onsite generators offer scalability and operational flexibility, aligning with the growing deployment of hydrogen infrastructure. This rising use of fuel cells in clean mobility and distributed energy sectors is expected to accelerate market penetration in the coming years.
Key Trends & Opportunities
Adoption of Green Hydrogen through Electrolysis
Electrolysis-based onsite hydrogen generation is emerging as a key opportunity, supported by the integration of renewable energy sources such as solar and wind. Unlike steam reforming, electrolysis provides zero-carbon hydrogen production, making it central to decarbonization strategies. Falling renewable energy costs and technological improvements in electrolyzers are enhancing efficiency and affordability. Governments and industries investing in green hydrogen corridors and pilot projects are driving early adoption. This trend positions electrolysis as one of the fastest-growing segments in the onsite hydrogen generator market.
- For instance, Cockerill Jingli Hydrogen produces pressurized alkaline electrolyzer systems with single-stack capacities of 5 MW. These electrolyzers are capable of producing over 1,000 Nm³/h of hydrogen and can be integrated with purification systems to achieve 99.999% purity.
Integration into Distributed Energy and Microgrids
The growing demand for decentralized energy solutions is creating opportunities for onsite hydrogen generators in distributed energy and microgrid systems. Hydrogen can act as both a fuel and energy storage medium, ensuring reliable power supply in regions with intermittent renewable resources. Onsite generation reduces transmission losses and supports energy independence for industrial facilities, remote locations, and commercial establishments. With increasing emphasis on energy security and resilience, the integration of hydrogen generators into hybrid renewable systems is becoming a strategic opportunity for both energy providers and end-users.
- For instance, Element 1 Corp. manufactures the L18-PSA methanol-to-hydrogen generator, which is designed to be paired with a third-party pressure-swing absorption (PSA) unit to produce high-purity, fuel cell-grade hydrogen.
Key Challenges
High Capital and Operational Costs
Onsite hydrogen generators require significant initial investment, particularly for electrolysis systems designed for green hydrogen production. The costs of electrolyzers, compressors, and storage infrastructure remain high compared to conventional hydrogen sourcing. Operational expenses, including energy requirements, further add to the financial burden. This makes adoption challenging for small and medium-scale industries in cost-sensitive regions. Without further cost reductions and financial support mechanisms, high capital intensity will continue to hinder wider market penetration.
Infrastructure and Supply Chain Limitations
Despite rising interest in hydrogen, the lack of supporting infrastructure poses a major challenge to market growth. Many regions still lack the distribution networks, refueling stations, and storage facilities needed to integrate onsite hydrogen generators into broader energy ecosystems. Limited supply chains for advanced components such as membranes and catalysts also affect deployment timelines. These gaps restrict scalability and discourage investment, particularly in emerging economies. Expanding infrastructure and securing robust supply chains will be critical for unlocking the full potential of onsite hydrogen generation.
