The long trip thing seems to be best addressed with trailers having ICE in them. The car industry is bent on having hybrids simply because they can make more money producing replacement parts and performing maintenance on them versus a pure EV. However, I agree owning EV's in the city would require infrastructure.
There is a senior project at my university, for mechanical engineers, that is involved in testing hydrogen cars and the fueling station. Montpelier, VT is the testing center outside of CA because of it's extreme temperatures (-45 to 100 F), mountains, and greenies. Anyways, the hydrogen fueling station is ran off of a windmill. There are some pretty large losses in creating the hydrogen and in storing it. It's looking worse and worse as we start actually measuring the efficiencies of the equipment and car. Batteries may be less convenient but they are FAR superior.
I can report back in April with the final testing results and had numbers if you guys are interested.
