“With a new national commitment, our scientists and engineers will overcome obstacles to taking these cars from laboratory to showroom, so that the first car driven by a child born today could be powered by hydrogen, and pollution-free.”

Back in the early 2000s, the Hydrogen Economy had become all the rage in energy and environment discussions, and even the president caught the bug. The hydrogen car was going to be awesome because it was going to use a fuel cell that made emissions consisting of only water. While making a commercially-viable hydrogen fuel cell car a reality would be a major feat of engineering, government policy, and business, the real linchpin was where the hydrogen was going to come from. Getting it from natural gas would be a bummer because the whole point was that it should be a clean fuel! It needed to come from solar or wind power.
