Researchers at GFZ Helmholtz Centre for Geosciences have utilized state-of-the-art plate tectonic modelling to pinpoint potential natural hydrogen hotspots in mountain ranges. These hotspots could hold the key to large-scale natural hydrogen generation, surpassing current synthetic production methods. By studying geological processes that trigger hydrogen formation, such as serpentinisation of mantle rocks, the team led by Dr Frank Zwaan has shed light on where and when natural hydrogen accumulations can be found. Their findings suggest that mountain ranges offer optimal conditions for hydrogen generation due to exhumed mantle rocks coming into contact with water at favorable temperatures. The study emphasizes the significance of tectonic history in controlling the formation of economic hydrogen reservoirs. Ongoing exploration efforts in regions like the Pyrenees and European Alps aim to capitalize on these revelations. The research underscores the potential of natural hydrogen as a clean energy source and highlights the importance of innovative exploration strategies in uncovering its full potential.
