A watt-hr is a watt-hr. It bears no marker of having been created by burning algae or fissioning uranium. Your electric bill contains that information - abundantly. Nobody cheats on thermodynamics.
Chemical & Engineering News 83(34) 42 (2005) "Filling up with hydrogen" Enviro-whiner crap. Etc.etc....
I'm not fully conversant with the mathematics that Uncle Al has given in his full reply.
But it does seem to me that Hydrogen stored in whatever form, even a Clathrate, (apart from very dangerous high comression)could never be released in a sufficient quantity to power the modern car, for the length of time and speeds it travels today
Prehaps a simple 15% mixture of Hydrogen mixed with one or more other inert gases and moderately compressed, might power a piston vehicle at a much reduced velocity?
I have lost faith in Hydrogen ever being used neat, as an explosive gas to drive a piston engine. Prehaps a hybrid vehicle using a Hydrogen Cell to produce electricity plus a small simple gasolene engine is the way forward?
