Hydrogen, hailed as a green energy alternative, is gaining attention for its potential to reduce carbon emissions and meet the energy demands of modern society. While the current hydrogen production heavily relies on hydrocarbons like natural gas, scientists are actively working on ways to produce hydrogen using renewable sources. A recent study from the University of Oxford, the University of Durham, and the University of Toronto has identified potential geological environments harboring natural hydrogen reserves that could have accumulated over the Earth's billion-year history. Although accessing all of this hydrogen may not be feasible, even extracting a fraction of it could significantly lower carbon emissions and provide a sustainable energy source. The study's 'exploration recipe' aims to pinpoint areas where natural hydrogen could be commercially viable to extract, potentially revolutionizing the current hydrogen supply chain. Not limited to hydrogen, researchers are also focusing on locating hidden reserves of helium, which is crucial for various applications such as cooling superconductors. The establishment of Snowfox Discovery, a company dedicated to finding natural hydrogen accumulations, underscores the commitment to uncovering sustainable energy sources for the future.
