Hydrogen as a transportation fuel

In their recent article in Environment, Marc W. Jensen and Marc Ross bring an overdue dose of realism to the debate on hydrogen as a transportation fuel by stressing the importance of a refueling infrastructure. They are correct that gasoline- and methanol-powered fuel cell vehicles are problematic, but their article, like much of the current discussion of hydrogen, is misleading because it focuses uncritically on near-term applications of fuel cells in automobiles. This error comes about by backing into the issue of hydrogen after asking, How might automotive technologies evolve to solve pollution and climate problems?
