Plus bill gates kind of money!

Almost all of the commercially available H comes from Natural Gas steam shift reactors. Definately has a carbon footprint, The rest comes from splitting water, which mostly get's it's electricity from the grid.

There is no free hydrogen.

I guess it goes back to a question similar to the original, what is the environmental impact from generating hydrogen? That isn't the biggest question for me though. It will take some time for me to be convinced it is safe for the same dumbasses that can't drive normal cars to be wheeling around with thousands of PSI of Hindenburg gas attached to their vehicle.

More like nuclear Pinto. I can only imagine having to evacuate a highway every time a car catches on fire. Are firefighters going to go anywhere near one?

What is the Enviro impact when two battery powered cars crash into each other and split those cases open?

I don't believe any manufacturer is using lead-acid batteries in hybrids, so it could be worse. Nickel-metal-hydride batteries are currently in vogue and while nickel isn't supposed to be very good for you it is a lot better than acid and lead coming out of everything. Lithium ion is probably going to be the next step and is supposed to be better than nickel on the environmental front. Lithium polymer, probably the best technology from an environmental and efficiency standpoint, has its own problems. If they suffer an impact leading to a short or are charged too quickly they ignite and burn vigorously.
