A recent study indicates the existence of substantial reservoirs of naturally occurring hydrogen gas hidden in mountain ranges worldwide, potentially unlocking a vast source of clean energy. The research, combining field recordings and computer modeling, explores how plate tectonic movement and mountain formation contribute to the production of hydrogen gas over millions of years. While artificial hydrogen production emits greenhouse gases, finding natural reserves could significantly advance clean energy technology. The study focuses on serpentinization, a process where the Earth's mantle reacts with water to produce hydrogen gas, more common in mountain ranges. The researchers identified potential locations and processes for natural hydrogen formation, emphasizing the economic opportunities associated with these discoveries. Plans are already in motion to explore hydrogen reservoirs in the Pyrenees, European Alps, and the Balkans. The research sheds light on the potential for a new natural hydrogen industry and emphasizes the importance of sustainable exploration strategies. This groundbreaking study offers hope for a cleaner energy future and signals a turning point in natural H2 exploration.
