Abstract

A method for the production of ammonia. The method includes the reduction of steam using a metal species such as iron or tin to form pure hydrogen gas and the reaction of hydrogen gas with nitrogen gas to form ammonia. The nitrogen gas can be formed by extracting the oxygen from air through the oxidation of a metal, yielding nitrogen gas.
