Abstract

The invention provides a process for producing hydrogen having the steps of reacting a fuel with a combination of two oxygen carriers to produce gaseous products and reduced oxygen carriers; reacting a portion of the reduced oxygen carriers with steam to generate hydrogen and partially oxidized oxygen carriers; and reacting the partially oxidized oxygen carriers and remaining reduced oxygen carriers with air to generate heat and regenerate the two oxygen carriers in their original oxidation state, wherein the heat and regenerated oxygen carriers are reused.
