How it works

Deep faults and serpentinizing rock (olivine reacting with water) can generate hydrogen gas continuously — "natural" or "geologic" hydrogen, unlike hydrogen made by electrolysis. This cross-section follows the gas from the reservoir, up the wellbore, through a membrane separator that concentrates H₂ away from nitrogen and methane, and into surface storage.

Well flow rate — how fast gas is drawn from the reservoir; higher flow also wets the membranes faster.
Membrane purification — how aggressively the separator strips out associated gas; higher settings raise purity but the membranes absorb more moisture per second.
Reservoir — the geological setting: a weak serpentinite body yields less hydrogen per unit flow than an active fault, and an H₂-rich reservoir yields the most.
Dry membranes — purges accumulated moisture; without it, purity keeps falling as the membranes saturate.

Real-world relevance: several countries are now drilling exploration wells for naturally occurring hydrogen seeps and faults, a potential low-carbon energy source that does not require an electrolyzer at all.

Gas from the fault undergoes separation as membranes concentrate the natural hydrogen
