It would be foolhardy to store hydrogen gas in an automobile. The Hindenburg taught us this. Storing more than 25 cycles of hydrogen as a gas while also being used as a fuel source for an engine is banned here, and should be legally banned in the nation.

The sensible way to store or use hydrogen as fuel is in water. Until that technology is prepared for the public market metal hydrides are the way to go. We can use the hydride batteries as part of the frame, or as a functional metal bumper, and have them [both] replaced at fuelling stations, until water approaches. Considering probable events, water hydrogen technology should be approaching by around 2009 for general use, and afterwards in cars becoming fashionable around 2010.
