There is another more pressing issue with the change over to hydrogen. 
Studies suggest that it may be as bad or worse than flourocarbons at 
damaging the ozone layer. I don't have the relevant citations on hand 
but it was in the news last winter. They talked about leakage during 
refueling, from tanks and equipment being a major problem and 
essencially unsolvable. Google if you want.
