In places where they don't have water, hydrogen can also be reformed from natural gas.

Yeah, but water's pretty well-built stuff. Takes a boat-load of energy to take it apart. And that energy's got to come from somewhere, and might be more efficiently used to simply charge a battery. (Oh, yeah, and thre's the whole energy expenditure to compress and pump hydrogen into tanks . . . that takes another toll.)
