Abstract
A method and apparatus for the production of hydrogen gas. The method includes the reduction of steam utilizing a metal species, such as iron or tin, to form pure hydrogen gas. At least two reactors are preferably utilized to continuously form additional metal for the reduction of the steam by reducing a metal oxide. No substantial transport of the non-gaseous reactants (e.g., the metal and metal oxide) is required, thereby simplifying the apparatus and reducing the overall cost of the hydrogen production.
