A recent study has shed light on the existence of possibly trillions of metric tons of natural hydrogen beneath the Earth's surface. While hydrogen has long been considered a key player in achieving a net-zero carbon emissions future due to its clean energy characteristics, its production has been largely reliant on expensive methods like creating 'green' hydrogen using renewable energy sources. The discovery of natural hydrogen reservoirs in locations like Mali has sparked a global interest in exploring this alternative source. The study acknowledges uncertainties regarding the exact amount and accessibility of the natural hydrogen reservoirs, but the potential is vast. Just a small fraction of the estimated reserves could meet global hydrogen demand for the next two centuries. However, questions remain about the feasibility and consequences of exploiting this resource, including concerns about the stability and sustainability of using such a large amount of largely unexplored fuel type. Despite these uncertainties, the findings have injected hope into the vision of a hydrogen-powered future. With the publication of this study in Science Advances, researchers have highlighted the need for further exploration and research in this field to better understand and utilize the potential of natural hydrogen. While challenges and unanswered questions persist, the study points towards a potentially groundbreaking shift in the energy industry towards harnessing the vast natural hydrogen resources beneath our feet.
