Global Electrolyzer Market - Growth, Trends, and Forecast to 2031

The global electrolyzer market witnessed acceleration in 2025, with installed electrolysis capacity more than doubling year-on-year to exceed 4 GW, compared with around 2 GW in 2024. This rapid expansion was driven by the commissioning of large-scale hydrogen infrastructure projects, particularly in China, alongside growing investments in green hydrogen projects.

However, despite strong growth in deployment, the market continues to face a significant imbalance between electrolyzer manufacturing capacity and actual project demand, resulting in intense price competition and increasing pressure on manufacturers.

Market Definition

The global electrolyzers market refers to the worldwide market for electrolyzer systems and related equipment used to produce hydrogen by splitting water into hydrogen and oxygen using electricity. 

The market primarily comprises alkaline electrolyzer (ALK), proton exchange membrane (PEM), solid oxide electrolyzer cell (SOEC), and anion exchange membrane (AEM) electrolyzer technology. Demand is mainly driven by the production of renewable hydrogen and low emissions hydrogen for applications such as ammonia and fertilizer production, refining, steel, chemicals, fuel cells, e-fuels, mobility, and energy storage. supporting market growth.

Drivers

Supportive Government Policies and Subsidies 

Supportive government policies and hydrogen targets: EU initiatives such as REPowerEU, which targets 10 Mt of domestic renewable hydrogen production and 10 Mt of imports by 2030, are driving investments in large-scale electrolyzer projects.

In May 2026, the European Commission selected nine renewable hydrogen projects across seven European countries under its third European Hydrogen Bank auction. The projects are expected to install almost 1.1 GW of electrolyzer capacity and produce more than 1.3 million tonnes of hydrogen over their first 10 years, supported by more than EUR 1 billion in EU funding.

The EU's Net-Zero Industry Act (NZIA) identifies electrolyzers as a strategic net-zero technology and aims to build manufacturing capacity capable of meeting at least 40% of the EU's annual deployment needs by 2030. The policy is expected to encourage investment in electrolyzer manufacturing, strengthen the European supply chain, and support the deployment of electrolyzers for renewable hydrogen production.

In July 2026, the European Commission issued guidance under the NZIA requiring sustainability and supply-chain resilience criteria to be considered in public procurement and renewable-energy auctions. The measure is expected to strengthen the competitiveness of EU-based clean-technology manufacturers, including electrolyzer suppliers, while reducing dependence on concentrated overseas supply chains.  

Restraints 

High CAPEX, power generation costs, and financing costs continue to make green hydrogen less competitive with conventional hydrogen. Electricity can account for a major share of hydrogen production costs, while high interest rates and perceived project risks increase the cost of financing. This makes many electrolyzer projects dependent on government subsidies and long-term contracts.

In September 2025, Salzgitter delayed the second and third phases of its EUR 2.5 billion SALCOS green steel project by around three years, citing unfavorable economic conditions, slow regulatory progress, and an underdeveloped hydrogen market. The first phase, supported by around EUR 1 billion in grants, is continuing, but the later phases were postponed to reduce near-term capital expenditure.

The production of electrolyzers depends on specialized components and materials, including iridium and platinum for PEM systems, as well as transformers, power electronics, membranes, and other balance-of-plant components. Limited availability, long equipment lead times, and geopolitical concentration of certain raw materials can increase costs and delay projects.

In 2026, severe shortages of high-voltage power transformers in the U.S. were causing project delays and extending delivery times to as much as four years. The shortage was driven by surging demand from data centers, renewable-energy projects, factories, and grid expansion. Developers increasingly began pre-ordering transformers and securing factory production slots years in advance, making equipment availability a major constraint for large-scale energy projects.

Market Opportunity

The decarbonization of steel, ammonia, fertilizers, refining, chemicals, shipping, and e-fuels represents the largest long-term opportunity for electrolyzer suppliers. Increasing demand for low-emission hydrogen is driving developers toward large-scale electrolyzer installations, creating opportunities for OEMs, system integrators, and component suppliers. 

The opportunity is becoming increasingly commercial as companies move from small demonstration projects toward 100-MW, 500-MW, and GW-scale electrolyzer installations. This creates opportunities not only for electrolyzer manufacturers but also for stack suppliers, membrane and catalyst manufacturers, power-electronics providers, engineering companies, system integrators, and long-term service providers. 

Segment Analysis 

The global electrolyzer market is segmented into two primary categories: technology and capacity. These segments are classified based on the electrolysis technology used and the electrolyzer system capacity.

By Technology

Alkaline Electrolyzer (ALK): The dominant technology due to its maturity, lower cost, and suitability for large-scale hydrogen production, particularly in China.

Proton Exchange Membrane Electrolyzer (PEM electrolyzer): PEM electrolyzers offer fast response times and are well suited to variable renewable energy sources.

Solid Oxide Electrolyzer Cells (SOEC): Use high-temperature steam electrolysis to achieve high efficiency, particularly when integrated with industrial processes that provide waste heat. 

Anion Exchange Membrane (AEM): An emerging technology combining PEM-like flexibility with lower-cost materials, offering potential for reduced electrolyzer costs.

By Capacity

Small-Scale (<100 MW): Mainly used for smaller commercial and demonstration projects.

Medium-Scale (100-500 MW): The fastest-growing segment, driven by large industrial projects.

Large-Scale (500-1,000 MW): Includes utility-scale projects supplying major industrial facilities and hydrogen hubs.

Gigawatt-Scale (>1 GW): Includes mega-projects for large-scale hydrogen production and exports, such as the ~2.2 GW NEOM project in Saudi Arabia.

Regional Analysis
