I hope you are right Jim, but I suspect the oil companies will continue to keep their oily fingers on the scales to promote wasteful solutions. The real "weak link" is the actual usefulness of a hydrogen infrastructure. Currently it is extremely pollution intensive to make H2. To actually use it for transportation requires technological breakthroughs in many areas - carbon sequestration, fuel cells (they've been working on these for over 150 years), and storge methods -- there is more hydrogen in a gallon of gasoline than in a gallon of liquid hydrogen, and gasoline doesn't boil off. None of it can compare to other, more practical transportation solutions:
Electricity, from renewables or coal, can be used more efficiently in electric cars.
Biofuels in internal combustion engines are more energy dense and have much fewer safety issues.
Fuel cells can be developed to use any liquid fuel, not just hydrogen, eliminating all the storage and transportation issues of hydrogen gas. If aluminum is used to generate hydrogen on demand, the energy and pollution associated with aluminum mining and smelting must add in, making it far less attractive.
I don't see a single case where H2 makes sense to move a vehicle. Maybe someone can point one out, hopefully with a scientific basis and sans insults.
