Not to worry about hydrogen, Alex. A fuel cell based on methane--already available as natural gas--would do the trick and we already have a distribution network in place. I believe some materials such as activated carbon and perhaps carbon nanotubes readily absorb methane, so need for high-pressure storage tanks or cryogenic delivery of liquid hydrogen. Flue cerlls run hot, though, so we still must content with high temps, which can limit use in vehicles.
