NOVELTY - Producing hydrogen from dissociating water and hydrocarbon fuels comprises mixing, atomizing and vaporizing water (60) and hydrocarbon fuel (50); heating the vaporized water and hydrocarbon fuel mixture in a heat exchanger (90); and passing the vaporized mixture to a plasma reformer (100), dissociating water and hydrocarbon fuel, and forming a reformate stream containing hydrogen, carbon monoxide, carbon dioxide, and trace hydrocarbons in a reaction chamber of the plasma reformer in an intense electron field between emitting electrodes and collecting electrodes at 400-1900 degrees C in the chamber.    USE - Method for producing hydrogen (claimed).    ADVANTAGE - The method replaces hydrocarbon fuels with water as a fuel for producing hydrogen. Preliminary cost estimates based on water replacing 50% of the hydrocarbon fuel and a nearly 100% primary energy efficiency indicate that a cost of less than 2 dollars per kg of hydrogen can be achieved. The method also eliminates the undesirable consequences of using combustion. The primary energy source for the method is electricity. This allows for quick starts and provides control for maintaining optimum conditions for hydrogen production.    DETAILED DESCRIPTION - Producing hydrogen from dissociating water and hydrocarbon fuels comprises mixing, atomizing and vaporizing water and hydrocarbon fuel; heating the vaporized water and hydrocarbon fuel mixture in a heat exchanger; passing the vaporized mixture to a plasma reformer, dissociating water and hydrocarbon fuel, and forming a reformate stream containing hydrogen, carbon monoxide, carbon dioxide, and trace hydrocarbons in a reaction chamber of the plasma reformer in an intense electron field between emitting electrodes and collecting electrodes at 400-1900 degrees C in the chamber; converting carbon monoxide in the reformate stream and adding water to hydrogen and carbon dioxide in a water shift reactor (110); and cooling the reformate stream from the water shift reactor in the heat exchanger and heating the vaporized water and hydrocarbon fuel mixture entering the heat exchanger.
