As was posted previously, fundamental science demonstrates that hydrogen as a fuel is not possible. Hydrogen has too little energy per pound and requires too much energy to deliver. Basic science numbers demonstrate that hydorgen as a fuel would result in something like 80% loss of energy by the time that fuel gets to the vehicle.

Curious that GM management is pushing hydrogen since GM top management is devoid of technical competance. The realities of science says hydrogen is a lousy fuel for too many reasons. But then GM also created the EV-1. Then outright lies about its numbers such as range. The real world range for EV-1 (the all electric car) was about 60 miles. GM would not even let EV-1 designers use anything but lead acid batteries because GM did not make batteries of other technologies. This is the same GM that says hydrogen is the future? "Fool me once- shame on you. Fool me tens of times ... at what point do I finally get it?"

Hydrogen has other interesting and practical applications. Batteries based upon hydrogen look particularly promising. No other fuel has the energy per pound numbers that petroleum provides. Those numbers damn hydrogen as a totally impractical fuel. Again, seek that recent and previous discussion here about hydrogen.
