Recent research unveils the immense potential of natural hydrogen as a clean energy source that could power the planet for 170,000 years. Unlike hydrogen derived from hydrocarbons, natural hydrogen forms without human intervention through geochemical reactions, emitting no carbon and requiring no external energy input. To access this hidden treasure, critical geological conditions must be met, including the presence of a production source, a gas storage reservoir, and a geological barrier. Promising regions for hydrogen accumulation include ophiolites, igneous provinces, and ancient greenstone belts. However, the presence of subsurface bacteria consuming hydrogen poses a challenge, necessitating careful exploration to maximize exploitable reserves. The study offers a roadmap for energy companies to explore economically viable deposits and identifies areas with potential for significant hydrogen reserves. While uncertainties exist about the extractable quantity of natural hydrogen, its immense prospects make it a crucial player in the global energy transition towards a more sustainable future.
