General Information:


Water can be produced on the Moon by adding hydrogen to the lunar regolith.

When heated to 1000 degrees Celsius, iron oxide contained in the regolith reacts with the added hydrogen to produce water, which can then be split into oxygen and hydrogen again through electrolysis.1

Reduction: FeTiO3+H2 ----> Fe+TiO2+H2O

Electrolysis: 2H2O ----> 2 H2+ O2
