A recent study by researchers at the GFZ Helmholtz Centre for Geosciences has uncovered the potential for mountain ranges like the Pyrenees, Alps, and parts of the Himalayas to serve as vast reserves of natural hydrogen. This discovery challenges previous assumptions by highlighting mountains as productive hydrogen reservoirs due to the process of serpentinization, where deep mantle rocks interact with water, releasing hydrogen gas. The study, published in Science Advances, emphasizes the ideal conditions in mountainous environments for large-scale natural hydrogen generation, with plate tectonic modeling pinpointing regions conducive to hydrogen accumulation. This finding could significantly impact global energy dynamics by offering a cleaner, more efficient alternative to traditional hydrogen production methods. Scientists advocate for increased exploration efforts in mountain regions to confirm the commercial viability of these hydrogen deposits, with ongoing projects in the Pyrenees, Alps, and Balkans showing promising results. Success in this field will require innovative exploration strategies to identify suitable drilling sites through a deep understanding of the tectonic history of each location. The continuous nature of hydrogen generation through serpentinization suggests the potential for a self-replenishing natural hydrogen industry, revolutionizing the energy market. If confirmed, this discovery could lead to mountains playing a pivotal role in hydrogen extraction, offering a low-cost, carbon-free energy source for industries like aviation, steelmaking, and heavy transport.
