ABSTRACT:
A method for producing hydrogen from water in which hydrogen is produced by reducing water using metallic germanium and the by-product, germanium monoxide, is reduced with a reducing agent to metallic germanium which is recycled and reused. In this case, it is necessary to regulate the oxidation of metallic germanium so as to stop at the germanium monoxide stage since the reduction of germanium dioxide to metallic germanium is difficult. Therefore, water vapor is advantageously reduced by using not less than 1 mole of metallic germanium to 1 mole of water vapor or it is indirectly reduced with an intermediate of carbon dioxide.
