Experimental Proof to Natural Hydrogen Generated Through Serpentinization of Olivine at Room Temperature and Ambient Pressure With Mechanochemistry

Natural hydrogen, or "white hydrogen," is a promising low-cost, low emission, yet abundant form of hydrogen. The redox reaction between water and iron(II) species in minerals such as olivine is considered the most important process (e.g., serpentinization) to generate natural hydrogen. Instead of at high temperatures or pressures, this work presents the possibility of the reaction via only mechanical energy input.
