Leading Electrolyzer Manufacturers: Market Overview, Recent Developments, Active and Upcoming Projects, and Policies

Explore the global electrolyzer market, hydrogen capacity forecasts, electrolysis technologies, leading manufacturers, major projects, production costs, and policy developments.

Why Does the Global Electrolyzer Market Matter?

The global low-carbon hydrogen market is evolving as governments and energy companies balance energy security, decarbonization targets, and industrial competitiveness. While blue hydrogen has driven much of the recent growth in operational capacity, green hydrogen is expected to expand more rapidly between 2025 and 2030, creating potential opportunities for electrolyzer manufacturers and technology providers.

However, the market faces commercial challenges, including high green hydrogen production costs, uncertain offtake demand, project delays, and near-term electrolyzer overcapacity. The competitiveness of different electrolysis technologies increasingly depends on project bankability, supply-chain maturity, manufacturing scale, and policy support.

Key Highlights

Global low-carbon hydrogen capacity grew 34% from 2024 to 2025, with energy security increasingly driving capacity additions.

This growth can be largely attributed to the faster build-out of blue hydrogen capacity through grey hydrogen retrofits. As a result, blue hydrogen accounts for ~76% of global active capacity.

Green hydrogen capacity is projected to grow most rapidly between 2025 and 2030, at a 168% CAGR, based on announced projects.

The IEA estimates current green hydrogen production costs at approximately US$3/kg to more than US$10/kg, reflecting wide variation in power prices, project utilization, and financing conditions across regions.

GlobalData estimates, based on announced projects, that total electrolysis capacity could reach ~414GW by 2030, which remains below the IEA’s 560GW 2030 benchmark required to align with its Net Zero Emissions by 2050 (NZE) scenario.
