How Nature Makes Hydrogen

Caption

Nature produces hydrogen through "serpentinization." When water meets the ubiquitous mineral olivine under pressure, the rock absorbs mostly oxygen (O) atoms from H2O, transforming olivine into another mineral, serpentine -- characterized by a scaly, green-brown surface appearance like snakeskin. The complex network of fracturing and created by serpentinization also creates habitat for subsurface microbial communities. Image from Gros Morne National Park, Newfoundland, Canada.
