Heat transfer issues associated with four alternative hydrogen storage methods are discussed with emphasis on vehicle applications. Considered are compressed hydrogen, liquid hydrogen, metal hydrides, and chemical hydrides. For compressed hydrogen storage, efficient heat transfer during compression and intercooling decreases compression work. Enhanced heat transfer inside the tank during the fueling process can minimize additional compression work. For liquid hydrogen storage, improved thermal insulation of cryogenic tanks can significantly reduce energy loss caused by liquid boil-off. For metal hydride storage, enhanced heat transfer is essential because of the low effective thermal conductivity of particle beds. Enhanced heat transfer is necessary to ensure that both hydriding and dehydriding processes achieve completion and to prevent hydride bed meltdown. For chemical hydride storage, innovative vehicle cooling design will be needed to enable their acceptance.
