The global supply of electrolysers will not be enough to meet demand for green hydrogen by 2030 even in the least bullish scenarios, according to analysis by US investment bank and financial services firm Jefferies.

In a 45-page report for clients, entitled Plugging into the Hydrogen Ecosystem, the New York-headquartered company estimates that the worldwide supply of electrolysers in 2030 “could sit somewhere in the 30-40GW range”.

This compares to 54 gigawatts of announced projects and 94GW of what it calls “pledged” projects.
