TECHNOLOGY FOCUS - CHEMICAL ENGINEERING - Preferred Method: The reduction reaction is carried out over a time adequate to reduce most but not all the iron oxide to elemental iron. The reduction reaction is carried out at 500-1100, preferably 500-900 or 600-750degreesC. The method further includes generating heat in an after-burner by combusting residual conditioned hydrocarbon fuel from the high temperature electrochemical generator. The heat generated in the after-burner is supplied to promote the oxidation reaction of iron. The trace quantities of carbon monoxide in the hydrogen from the oxidation reaction of iron are removed using a process from methanation, preferential oxidation, or hydrogen gas separation. The hydrogen generated from the oxidation reaction of iron is stored and subsequently dispensed to vehicles. The oxidation reaction of iron is carried out under a pressure above atmospheric pressure. The reactants in the second bed are agitated mechanically. The first bed operates as a fluidized bed. A portion of the hydrogen produced in the oxidation reaction is provided to the anode chamber of the high temperature electrochemical cell for electricity generation. A portion of the hydrogen generated in the oxidation reaction of iron is provided to a low temperature fuel cell for electricity generation. A portion of an output gas from the high temperature electrochemical cell is recirculated to the second bed. The method is used at an energy station to provide electricity and hydrogen. Prior to the reduction reaction of iron oxide, the hydrocarbon gas is processed in a reforming processing that produces syngas from the hydrocarbon gas. A portion of the syngas is provided to the anode chamber of the high temperature electrochemical generator as fuel for electricity generation.    TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Component: The high temperature electrochemical generator comprises a molten carbonate fuel cell or a solid oxide fuel cell. The first and second beds each further include, as an oxygen source, any of ceria, zirconia, titania, and alumina. The low temperature fuel cell comprises a phosphoric acid fuel cell or a proton exchange membrane fuel cell. The first bed is exchanged with the second bed from time to time. The system further comprises an afterburner combusting residual conditioned hydrocarbon fuel from the high temperature electrochemical generator to generate heat, and a fuel reformer that processes the hydrocarbon gas to produce syngas for use in the reduction reaction of iron oxide. It is used at an energy station to provide electricity and hydrogen.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The hydrocarbon fuels include a gas from natural gas, propane, butane, parrafins, liquefied petroleum gas, gasoline, diesel, methanol, ethanol or propanol.
