While hydrogen is recognized as a clean energy source due to its emission of only water vapor when used, its current production mainly relies on natural gas, limiting its environmental benefits. Scientists are now focusing on 'gold hydrogen,' natural reserves of hydrogen found in Earth's mountains, which could be a game-changer in the decarbonization process. Recent research from the GFZ Helmholtz Centre for Geosciences in Potsdam, Germany, suggests that mountain ranges like the Alpide belt may hold significant amounts of hydrogen. By simulating plate tectonic processes, researchers have identified how hydrogen could be naturally produced in mountainous regions through serpentinization, a geologic process involving mantle rocks and water. The discovery of large hydrogen reserves in places like Bourakebougou, Mali, has spurred further exploration into natural hydrogen sources. This study marks a significant step in understanding the potential of 'gold hydrogen' and hints at the birth of a new industry focused on sustainable energy production. With ongoing efforts to improve hydrogen production and lower costs, the future may see a shift towards greener energy sources and reduced reliance on fossil fuels.
