What Is Covered Under Water Electrolysis Market?

Water electrolysis refers to the process of using electricity to split water (H₂O) into its constituent elements, such as hydrogen (H₂) and oxygen (O₂). When an electric current is passed through water containing an electrolyte, hydrogen is produced at the cathode (negative electrode) and oxygen at the anode (positive electrode). This method is widely used for producing hydrogen for industrial applications, clean energy, and fuel cells. The main types of products in the water electrolysis market are alkaline electrolyzer, proton exchange membrane (PEM) electrolyzer, solid oxide electrolyzer cell (SOEC), and anion exchange membrane (AEM) electrolyzer. Alkaline electrolysis involves using an alkaline electrolyte, such as potassium hydroxide (KOH) or sodium hydroxide (NaOH), to facilitate the electrolysis of water into hydrogen and oxygen. The input power options range from below 2 kW, 2 kW to 5 kW, and above 5 kW, while hydrogen production capacities include below 500 l/hr, 500 to 2000 l/hr, and above 2000 l/hr. The different end-user applications encompass ammonia production, methanol production, refining industry, power and energy storage, transportation or mobility industry, and others.

What Is The Water Electrolysis Market Growth Forecast?

The water electrolysis market size is expected to see strong growth in the next few years. It will grow to $13.16 billion in 2030 at a compound annual growth rate (CAGR) of 9.2%. The growth in the forecast period can be attributed to rising investments in hydrogen economy, increasing government decarbonization targets, expansion of renewable power capacity, growing adoption of hydrogen in mobility and storage, continuous reduction in electrolyzer costs. Major trends in the forecast period include expansion of green hydrogen production projects, rising adoption of pem and alkaline electrolyzers, growing integration with renewable energy sources, increasing focus on electrolyzer efficiency improvements, deployment of large-scale industrial electrolysis systems.

What Is The Driver Of The Water Electrolysis Market?

The rising demand for hydrogen production is expected to propel the growth of the water electrolysis market going forward. Hydrogen production refers to the process of generating hydrogen gas through various methods such as electrolysis, steam methane reforming, and biomass gasification. Hydrogen production is driven by the growing global emphasis on reducing carbon emissions and transitioning to cleaner energy sources. Water electrolysis helps in hydrogen production by using electricity to split water into hydrogen and oxygen, providing a clean and sustainable way to generate hydrogen fuel, especially when powered by renewable energy sources. For instance, in October 2024, according to the International Energy Agency (IEA), a France-based intergovernmental organization, global hydrogen production reached 97 million tonnes in 2023, of which less than 1% was produced through low-emissions pathways. The IEA also reported that installed water-electrolyser capacity rose to 1.4 GW by the end of 2023 and is expected to reach 5 GW by the end of 2024, with China accounting for nearly 70% of the committed additions. Therefore, the rising demand for hydrogen production is driving the growth of the water electrolysis industry.
