The problem with BEVs though is the potential chemical energy is not as high with today's battery technology as other sources are (i.e. standard fuels). The other issue is where we get electricity from. Here in California, where electricity mostly comes from Natural Gas, a BEV would not be any better than a fuel cell vehicle that gets Hydrogen from the same source of NG (although the infrastructure would not be as difficult to implement).
I'm wondering how the energy to drill and process Natural Gas for Hydrogen development compares to the energy needed for electrolysis of water to produce the same amount of Hydrogen. At the same time, would solar/wind power make sense to power the electrolysis process. According to Wikipedia, the
electrolysis of water is more efficient when salt is added to the solution.
Semi-random tangent question: Gas station storage tanks are notorious throughout history for leaking toxic gasoline into the ground. If a "gas" station supplying hydrogen had a leaky tank, would the hydrogen contaminate the ground in a toxic matter? If there was a leak could cleanup crews just oxygenate the ground to create water?
