Tech Insight: IEA projects that global electrolyzer capacity will exceed 150 GW by 2030, yet current output covers only about 5 % of anticipated demand.

Background

  • 2019‑2022: Early large‑scale electrolysis pilots in Germany and Japan.
  • 2023‑2025: EU’s “Hydrogen Valleys” program and the U.S. Clean Energy Act drive massive subsidies.
