Market Segmentation

By Technology

In 2024, the Alkaline Electrolyzer technology dominated the market due to its maturity, lower capital cost, and suitability for large-scale industrial hydrogen production. Alkaline systems have been widely adopted for decades and continue to benefit from optimized efficiency and long operational lifespan.

Proton Exchange Membrane (PEM) Electrolyzers are the fastest-growing segment, driven by their high efficiency, dynamic load response, and compatibility with fluctuating renewable energy sources. PEM systems are favored in mobility, distributed generation, and high-purity hydrogen applications.

Solid Oxide Electrolyzers (SOEC) are emerging as a breakthrough technology capable of high efficiencies when paired with industrial waste heat. Although currently in demonstration phase, SOEC is expected to gain traction in chemical and industrial processes.

By Renewable Sources

Wind energy accounted for a major share in 2024, especially in regions with abundant offshore and onshore wind capacity. Wind-to-hydrogen projects are rapidly scaling in Europe, North America, and Asia due to high capacity factors and established grid integration.

Solar energy is the fastest-growing renewable power source for hydrogen production, driven by declining photovoltaic costs and large-scale solar farm development in sunny regions. Solar-powered hydrogen production is particularly prominent in the Middle East, Australia, and India.

Geothermal energy offers reliable, baseload power for continuous hydrogen production and is gaining interest in regions with high geothermal potential such as Japan, Iceland, and parts of Europe.

Hydropower-based hydrogen leverages existing infrastructure and stable energy supply, making it ideal for large-scale, low-cost production in countries with significant hydro resources.

By Application

Power Generation was the leading application segment in 2024, as green hydrogen is increasingly used to produce electricity through fuel cells and hydrogen turbines. Utilities are integrating hydrogen into long-duration energy storage and grid balancing services.

Transport is the fastest-growing application, with hydrogen fuel being adopted in heavy-duty trucks, buses, trains, maritime vessels, and aviation. Hydrogen mobility is being prioritized where battery-electric solutions face range and weight limitations.

By End-User

Industrial users dominate the market as refineries, steel producers, chemical plants, and manufacturing industries replace fossil fuels and grey hydrogen with green hydrogen. Demand is being driven by carbon pricing, stricter emissions regulations, and sustainability commitments.

Mobility is a high-growth end-user segment, where hydrogen fuel cell vehicles and infrastructure are being deployed at commercial scale. Governments and automakers are investing heavily in fleet conversion and hydrogen refueling stations.

Chemical sector demand is growing as green hydrogen replaces traditional feedstocks in ammonia, methanol, and fertilizer production, facilitating low-carbon chemical manufacturing.

Power and grid injection applications are expanding as grid operators blend hydrogen with natural gas and use hydrogen storage to enhance grid resilience.
