Abstract
A method for the production of hydrogen gas. The hydrogen gas is formed by steam reduction using a metal/metal oxide couple to remove oxygen from water. Steam is contacted with a molten metal mixture including a first reactive metal such as iron dissolved in a diluent metal such as tin. The reactive metal oxidizes to a metal oxide, forming a hydrogen gas and the metal oxide can then be reduced back to the metal for further production of hydrogen without substantial movement of the metal or metal oxide to a second reactor.
