1. A method for coproduction of hydrogen, electrical power, and heat energy, comprising:
desulfurizing a feed stream to form a desulfurized feed stream;
pre-reforming the desulfurized feed stream to form a methane rich gas, wherein the pre-reforming is performed at a steam to carbon ratio (S/C) of about 3 to about 4;
providing the methane rich gas to a membrane separator comprising a water-gas shift catalyst to increase an amount of hydrogen in the methane rich gas, the membrane separator being operated at a temperature between about 300° C. and about 550° C.;
producing a hydrogen stream in a permeate from the membrane separator, wherein the hydrogen is compressed to about 400 bar to about 900 bar and dispensed to a fuel cell vehicle;
providing a retentate stream from the membrane separator to a solid oxide fuel cell (SOFC); and
producing electrical power and heat in the SOFC from the retentate stream.
