Integrated production of hydrogen, electricity, and heat

A trigeneration facility, comprising:

• a desulfurization unit to remove sulfur from a hydrocarbon feed stream forming a desulfurized feed stream;
• a pre-reformer to convert the desulfurized feed stream to a methane rich gas;
• a membrane separator to remove at least a portion of hydrogen from the methane rich gas in a permeate, the membrane separator comprising a water-gas shift catalyst to increase an amount of hydrogen in the methane rich gas;
• a compressed hydrogen stream of about 400 bar to about 900 bar, wherein the compressed hydrogen stream is a fuel stream to a fuel cell vehicle from the trigeneration facility;
• and
• a solid oxide fuel cell (SOFC) to generate electrical power and heat from a retentate from the membrane separator, wherein the retentate comprises methane.
