I don't think so.
H2 has the highest energy per mass(kg) than any other fuel... also has the lowest density(occupies too much volume)...The problem with H2 is that the molecule is so small that it would escape from normal fuel tanks... similar things with LPG... H2 and LPG are naturally excluded from endurance(long races)... of topic, but... but future of H2 may pass to "water"( anyone can laugh how much they want from ignorance) and super efficient forms of electrolysis(google HHOi).
Fuel cell are only around 30% efficient.. leaving modern diesel with the highest efficiency of all... I BET Audi will be diesel in 2011 or else they are in a retirement from race platform ...
