Reviewing the findings at the annual meeting of the American Association for the Advancement of Science, project leader Geoffrey Ellis said: “Most hydrogen is likely inaccessible, but a few per cent recovery would still supply all projected demand — 500mn tonnes a year — for hundreds of years.”
According to Paul Harraka, Chief Business Officer of US startup Koloma: “Geologic hydrogen represents an extraordinary opportunity to produce clean hydrogen in a way that is not only low carbon, but also low land footprint, low water footprint and low energy consumption”
Another US company, Natural Hydrogen Energy, has already drilled an exploratory well in Nebraska to tap this so-called ‘gold hydrogen’
