Europe’s mountain ranges may hide vast natural hydrogen reserves underground

A study led by the University of Lausanne and GFZ finds erosion can both promote and limit natural hydrogen formation and trapping in mountain belts.

Using numerical models, the researchers identified the Pyrenees and the Alps as the most promising European targets for hydrogen exploration.

The work suggests underground natural hydrogen could become a low-emissions energy source for transport and heavy industry if future studies confirm the findings.

By narrowing the best exploration areas, the study could help speed up searches for clean hydrogen resources in mountain ranges.
