Distribution is what will ultimately kill Hydrogen. If we have to transport, store and sell liquid or pressurized Hydrogen to cars it will never work out. As Will Gayther says everyone has an outlet in their home and can afford an extension cord. Now the electric companies are the largest network of automotive energy distributors in the world. All available right now with no significant infrastructure changes required. And since people will plug in at night it will help balance the electrical load.

Now Bush needs to pull his head out of his #$$% and pledge funding to improve power generation not hydrogen or ethanol production.
