In the first half of 2025, China's electrolyzer industry is experiencing significant policy support and market trends. The 'Medium and Long-Term Plan for the Development of the Hydrogen Energy Industry' underpins various technological approaches for electrolyzers. Policies align with different electrolyzer types: Alkaline electrolyzers receive support for large-scale applications, while PEM electrolyzers target breakthrough technologies like high current density. AEM electrolyzers focus on research support, and SOEC electrolyzers emphasize cutting-edge technology integration. Overseas, the EU and US prioritize carbon footprint reduction and green hydrogen projects. Market analysis reveals dominance of alkaline electrolyzers in large-scale projects in regions abundant in renewable resources. The future outlook predicts sustained growth in both domestic and overseas markets, with a shift towards advanced technical routes and increased competition.
