Forget it.
Even if we find a cheap, low energy, clean way of producing it, there are still big problems.
Hydrogen is 2700 times less energy dense than gasoline (by volume)! This means to bring it with you
in a car and get further than around the corner, you need to either.
- compress it bigtime
- cool it bigtime (liquify it)
To get the Hydrogen volume down to 3 times the volume of gasoline, you need to compress it
to 800 BARS!! To do that, you need a steel tank that weighs more than your car!!
Also, if you crash or somehow get a gas leak with this, I don't wan't to be in the same part of town.
Cooling it down is very energy consuming. Minimum 30% loss just there. Also, the tank itself needs
a very special design. Double with vaccum in between.
Also you will loose 5% energy each DAY by just having it in the tank. Not acceptable
unless you drive ALOT.
So, I doubt Hydogen will be the solution for a long time.. and probably not in airplanes.
