New Study Highlights Mountain Belts as Emerging Targets for Natural Hydrogen Exploration

A new international research study led by scientists from the University of Lausanne (Unil) and GFZ Helmholtz Centre for Geosciences explores how mountain-building processes and erosion influence the formation of natural hydrogen systems beneath major mountain ranges. 

The research builds on earlier work suggesting that certain tectonic environments — particularly regions where deep mantle rocks have been uplifted closer to the surface — may create favorable conditions for hydrogen generation through serpentinization, a natural chemical reaction between water and iron-rich rocks. 

One of the key findings is that erosion plays a dual role. Moderate erosion may help expose mantle rocks to the conditions needed for hydrogen generation, while excessive erosion could damage potential reservoir systems or disrupt the temperature conditions required for hydrogen formation and accumulation. 

Using advanced tectonic modeling, the researchers compared several European mountain systems and identified the Pyrenees as particularly favorable for natural hydrogen exploration, with the Alps also showing significant potential. The study also emphasizes that geological history — including ancient tectonic extension phases predating mountain formation — appears to influence hydrogen prospectivity. 

The broader implication is that natural hydrogen exploration is becoming increasingly grounded in large-scale geological system analysis, similar to how petroleum systems were historically evaluated. While the authors caution that further work is needed to identify commercially viable accumulations, the study adds to growing scientific interest in naturally occurring hydrogen as a potential future energy resource.
