Manufactured Subsurface Hydrogen (MSSH)

GeoKiln is pioneering Manufactured Subsurface Hydrogen (MSSH)—the only technology that engineers hydrogen directly within the earth, using proven oil & gas innovations to unlock low-cost, zero-carbon hydrogen at scale. By accelerating natural geologic processes with precision heat stimulation, we outperform green hydrogen in efficiency, cost, and scalability—delivering clean hydrogen at <$1/kg without water or emissions.
