Molecular hydrogen in surface and subsurface natural gases: Abundance, origins and ideas for deliberate exploration
AV Milkov - Earth-Science Reviews, 2022 - Elsevier
Geologic molecular hydrogen (H 2) occurs in the subsurface and vents and seeps at the
surface. However, this valuable natural resource is under-utilized in the economy because …
