They really need keep the work up on hydrogen fuel cells, that way we won't NEED to be reliant on the middle east.
A fully-integrated hydrogen economy would be at least a decade away, and that is only with an overly aggressive approach toward building the infrastructure necessary to its fruition.
Then, you're confronted with the fact that since hydrogen doesn't occur naturally in huge quantities, it must be produced by separating other chemical compounds. This takes ENERGY. As of right now, the most efficient means by which to produce hydrogen are through the expenditure of fossil fuels, especially natural gas.
And a huge problem here is that we are probably at least 25 years away from a hydrogen economy, if not more, based on the extremely limited amount of investment compared to what is required.
Right now, if you really want to attack the immediate problem, institute aggressive fuel efficiency standards and promote hybrid technology. Invest in public transportation and responsible growth policies that encourage people and businesses to locate in city centers rather than ever outward-creeping suburbs. Work on energy efficiency and decentralized power production. Now, none of this has to be to the exclusion of a hydrogen economy -- but it will go much further in reducing our dependence on oil, especially from the Middle East.
