Latest green hydrogen news: electrolysers, production projects, offtake deals, policy and costs across Europe, the Americas, Asia and Africa.

The efficiency limitations of water electrolysis remain one of the largest technical and economic barriers to scaling green hydrogen production. While renewable electricity costs have declined sharply over the past decade, the oxygen evolution reaction inside electrolyzers continues to require high energy input, slowing system efficiency and sustaining dependence on expensive precious metal catalysts such as iridium and ruthenium.
