Geez, I'm surprised you're even able to post on a forum.

I appreciate that you're interested in American energy policy but all the same you're vastly overgeneralizing a multi-faceted problem.
and less attacking the straw man please.

Not in its elemental form. Electrolysis requires an insane amount of energy to pull hydrogen out of water (although extracting from methane is easier, it also produces greenhouse gases). The only real advantage that fuel cells pose is that their thermal efficiency is dramatically higher than that of a combustible engine. And as for that "absolutely clean" nonsense... What do you think the power plants (which are directly responsible for production of hydrogen) produce?
In other words hydrogen's impact on the environment is just as significant as using fossil fuels...it just comes from different sources.
