A method for efficiently producing energy, carbon, carbon monoxide, synthetic carbonaceous liquid and gaseous fuels and hydrogen from fossil or biomass fuels with minimal carbon dioxide emissions. The method includes using an Electric Arc Hydrogen Plasma Black Reactor wherein hydrogen, carbon monoxide, carbon, ash and sulfur are produced and using a Direct Carbon Fuel Cell wherein a molten salt delivers the carbon produced from the reactor as a feedstock in the fuel cell to produce electricity and hot carbon dioxide gas.
