As an aside, hydrogen-powered vehicles would not generally be of the internal combustion type. A huge fraction of the fuel's energy is wasted as heat in the IC engines we use today. Instead, they would use electric motors and a fuel cell which uses the re-combination of H2 and O2 to produce electricity.

The idea of taking inefficient solar electricity to generate hydrogen to turn back into electricity is a little bit ludicrous.

edit: that last statement applies to "on-the-fly" applications, and not cases where you could store the H2 for later use, not really caring about the efficiency of that conversion.
