my understanding was that hydrogen would have a detremental effect on metal/the car itself... hence why its not used in current road going cars?
presumably cars that take hydrogen would have a special petrol tank???
The same problem exists with alcohol fuels such as e85 but almost 100% of the fuel system in a car is plastic these days so I don't see a problem.

In addition, I think the following are the qualifying factors for the anticipated use of the fuel in existing technologies;
A new technology that allows hydrogen to be stored in a cheap and practical way The company has found a low-cost way to trap the hydride compound inside a nano-porous polymer micro beadThe way I read this is that the process gets round the need to have special storage vessels (such as a fuel tank) in order to prevent evaporation and problems with volatility in the event of damage resulting from a collision.
The issue of taxation is another matter as it’s always difficult for governments to resist the temptation to maintain high prices when so many people seem resigned to paying them.
