Hydrogen Fuel in the Subcompact Automobile

Recent advances in hydrogen energy technology have made possible the consideration of a subcompact automobile utilizing metal hydrides, or powdered hydrogen storage, and a low cost electrolyzer for vehicle recharging. Basic considerations of the metal hydride automotive system are discussed regarding various vehicular prototypes. Particular emphasis is placed on a hydrogen minicar application. Utilizing a low cost electrolyzer and utility grid electricity for vehicle recharging, it is possible to make a comparison of the metal hydride hydrogen engine system with other electric vehicles on the basis of storage weight, vehicle range, and cost of operation.
