Mining Significance
Most hydrogen used today is manufactured rather than mined, but naturally occurring geologic hydrogen is an emerging exploration target. Geologic hydrogen can be generated by water-rock reactions, radiolysis, and other subsurface processes and may migrate into traps analogous to conventional gas accumulations. Exploration is still early-stage, so resource characterization, reservoir behavior, gas composition, deliverability, and economic recovery remain active areas of research.
