Researchers at the University of Oxford, Durham University and the University of Toronto have detailed the geological ingredients required to find clean sources of natural hydrogen beneath our feet. The work details the requirements for natural hydrogen, produced by the Earth itself over geological time, to accumulate in the crust, and identifies that the geological environments with those ingredients are widespread globally.
