But hydrogen can never establish itself as a dominant energy carrier. It has to be fabricated from high grade energy and it has to compete with high grade energy in the marketplace. Hydrogen cannot win this fight against its own energy source.

Oil has to be fabricated from biomass (ultimately, from solar energy). Has it won it's fight against its own energy source?
If the energy needs of the future are going to be met by wind or solar or hydroelectric, there's going to have to be some way of storing that power. I can't depend on a direct-powered solar car (I have to drive at night). I can't depend on a windmill on top of my car.
How long do I have to wait for the banana peel economy?
