Underground hydrogen exploration intensifies amid search for clean fuel

Researchers are exploring the potential of naturally occurring underground hydrogen, often referred to as "geologic hydrogen," as a clean fuel source. While estimates suggest trillions of tons of this hydrogen exist within Earth's crust, finding commercially viable reservoirs has proven challenging. Studies at locations like the Kidd Creek mine in Ontario have indicated modest but consistent production, suggesting that capturing this gas could provide a local energy source and demonstrate its practical use.
