A number of auto manufacturers are renewing their push for hydrogen, and now it is looking as though hydrogen cars will make it out of vehicular Death Valley. Last month Daimler, the German government, and several industrial companies announced a plan to build 1,000 hydrogen-fueling stations across Germany. Days later, Daimler CEO Dieter Zetsche showed off Mercedes-Benz's latest hydrogen-fueled effort, the F-Cell hatchback. Toyota this summer announced it would put hydrogen fuel-cell cars into production in 2015. Honda, GM, and Hyundai all have hydrogen fuel-cell programs running, and Honda actually has put vehicles -- heavily subsidized by the car maker, to be sure -- in the hands of some real customers, as opposed to its own engineers.
