Geological hydrogen, a relatively untapped resource, is gaining attention as a potential game-changer in the quest for clean energy solutions. The Yanartaş flames near Cirali, Türkiye, fueled by hydrogen from geological formations, have been burning for millennia, hinting at the vast reserves of this electron-rich gas waiting to be harnessed. In Bourakebougou, Mali, accidental discovery of a natural hydrogen reservoir led to the establishment of Hydroma, a company focused on leveraging geological hydrogen for electricity generation. US government researchers and a growing cohort of geochemists and entrepreneurs are exploring the possibilities of geological hydrogen as a sustainable energy source. By stimulating underground rocks and identifying existing hydrogen accumulations, these pioneers aim to bring low-carbon hydrogen to market at an affordable price point. While the industry is still in its infancy, with only a few productive projects like Bourakebougou, the potential for a new energy economy driven by geological hydrogen is tantalizing. The significance of geological hydrogen lies in its minimal impact on the environment compared to carbon-emitting fossil fuels. Through processes like serpentinization and radioactive decay, hydrogen is naturally produced and trapped in underground reservoirs. Recent studies from the US Geological Survey shed light on the creation, consumption, and release of hydrogen deep underground, providing valuable insights for further exploration and utilization. As the world shifts towards a more sustainable energy landscape, geological hydrogen represents a promising avenue for clean and cost-effective energy production. With ongoing research and exploration efforts underway globally, the dream of a widespread adoption of geological hydrogen as a primary energy source may soon become a reality.
