Geological hydrogen, sourced from natural formations like the Yanartaş flames in Türkiye and the underground reservoir in Bourakebougou, Mali, is emerging as a promising solution in the quest for clean and sustainable energy sources. With estimates suggesting that geological resources could offer vast amounts of clean hydrogen, the idea of tapping into existing hydrogen accumulations and stimulating underground rocks to produce more electron-rich gas has sparked the interest of energy entrepreneurs and investors worldwide. While the current focus on hydrogen as an energy carrier is prevalent, the potential of geological hydrogen to serve as a primary energy source with minimal environmental impact is gaining traction. The discovery of near-pure hydrogen in Bourakebougou has demonstrated the viability of utilizing geological formations for electricity generation and other energy applications. Efforts to explore and extract geological hydrogen are underway in various parts of the world, albeit mostly discreetly. The concept of serpentinization, where rock rich in iron and magnesium interacts with water to produce hydrogen, presents a unique opportunity for sustainable energy production. Despite the intricate chemistry and geology involved, recent studies, such as those conducted by the US Geological Survey, are shedding light on the mechanisms of hydrogen production, consumption, and storage deep underground. These developments signify a significant step towards realizing the potential of geological hydrogen as a key player in the transition to a low-carbon economy. By leveraging natural resources for clean energy solutions, geological hydrogen could revolutionize the energy sector and contribute substantially to mitigating climate change.
