Energy Seminar:week 7: Gold (natural) hydrogen: Pipeline or pipedream?
Chris Ballentine will speak in person at the Oxford Martin School. This is a hybrid event presented through TEAMS webinar online, for which registration is required (see below).
The oldest parts of the continental crust generate between 0.36–2.273×1011 moles H2 per year through water-rock reactions and radiolysis [1]. Over geological timescales the natural hydrogen generated would supply society’s current oil-equivalent needs with clean energy for well over 100,000 years. Natural (gold) hydrogen is found in many locations globally [1], but until recently has not been the focus of resource exploration. We show how Helium, generated during radiolysis, provides a key reference for understanding:

1. Whether the hydrogen generated in the deep crust is preserved [1,2]? 2. How and at what rate hydrogen escapes from the continental crust [3,4]? 3. Where the migrating crustal hydrogen might be focussed and accessibly trapped (and not consumed chemically or biologically) [3,5].

These provide the key steps in addressing whether, and where, natural (gold) hydrogen might provide a viable and significant clean energy resource.
