I would guess that a tank of hydrogen under pressure is much more expensive than a comparable amount of energy from gasoline?
I have read somewhere that hydrogen production from H2O in a car is 30 years away.

That is it... The only real way atm to create H2 and O2 from water is via electrolisys, the adding of electricity to the water to split the componants.
This requires energy, but so does the engine, sure the engine creates energy, but 90% of that goes into the wheels, and cannot be used for electrolisys. Thus, Perpetual motion, or Hybrid Hydrogen-Electric cars would have to be produced.
The problem with this tho, is the only real efficient and clean way of doing this is by the process of Nuclear Fusion (not the current Fission, found at Nuclear power stations today), however, Fusion is the same thing as what is going on in the Hydrogen engine (essentially), so they must perfect this first.
It is all a vicious cycle really, aint it?
*edit* btw: Hydrogen has much more energy produced when burnt than any form of conventional gasoline out. Sure, pressurised Hydrogen will be expensive, but a comparitable amount of gasoline is burnt, the Hydrogen will give off much more energy.
