Water Electrolysis Market Forecast 2026–2030: Size, Value And Compound Annual Growth Rate
The water electrolysis market has seen robust growth in recent years. It is anticipated to expand from $8.46 billion in 2025 to $9.26 billion in 2026, registering a compound annual growth rate (CAGR) of 9.4%. This historical growth can be attributed to several factors, including the rising industrial demand for hydrogen, the accessibility of grid-connected electricity, the initial adoption of alkaline electrolysis technology, the expansion of the chemical and refining industries, and the early incorporation of renewable energy.
The water electrolysis market size is projected to experience robust expansion over the next few years. It is expected to grow to $13.16 billion in 2030, achieving a compound annual growth rate (CAGR) of 9.2%. The anticipated growth during this period stems from increasing investments in the hydrogen economy, more stringent government decarbonization targets, the expansion of renewable power capacity, the rising utilization of hydrogen in mobility and storage applications, and the continuous reduction in electrolyzer costs. Significant trends for the forecast period include the proliferation of green hydrogen production projects, the rising adoption of PEM and alkaline electrolyzers, increasing integration with renewable energy sources, an intensified focus on improving electrolyzer efficiency, and the deployment of large-scale industrial electrolysis systems.

Water Electrolysis Market Growth Engine: The Factor Boosting Demand Globally
The anticipated increase in demand for hydrogen production is projected to drive the expansion of the water electrolysis market in the future. Hydrogen production involves generating hydrogen gas via diverse methods, including electrolysis, steam methane reforming, and biomass gasification. This production is fueled by the growing global emphasis on reducing carbon emissions and transitioning to cleaner energy sources. Water electrolysis aids hydrogen production by utilizing electricity to separate water into hydrogen and oxygen, offering a clean and sustainable method for creating hydrogen fuel, particularly when renewable energy sources are employed. For example, the International Energy Agency (IEA), a France-based intergovernmental organization, reported in October 2024 that global hydrogen production hit 97 million tonnes in 2023, with less than 1% originating from low-emissions pathways. Furthermore, the IEA indicated that installed water-electrolyser capacity increased to 1.4 GW by the close of 2023 and is projected to achieve 5 GW by the end of 2024, with China contributing nearly 70% of the pledged additions. Consequently, the increasing requirement for hydrogen production is propelling the expansion of the water electrolysis market.
