                Only a small fraction of the total project pipeline can realistically start operating by 2030, highlighting policy gaps The potential low-emissions hydrogen production from announced projects that could be available by 2030 has declined compared to in Global Hydrogen Review 2024.

In addition, we estimate that half of the announced projects face deferred start dates compared to the commercial operation date announced by developers. Delays are particularly acute among electrolyser projects…
