Challenging Gasoline: Diesel, Ethanol, Hydrogen

New York Times:
Yes, gasoline has the corner on the American car fuel market, but maybe not forever. Carmakers already produce passenger vehicles that run nicely on diesel fuel, ethanol or hydrogen. The first two are on the road in the millions around the world, and the third is moving slowly toward viability.
The catch is that the path to the pump, as Thomas Hobbes might have said, can be nasty, brutish and long. And the overall picture for pollution and energy — which the engineers call “well to wheels” — might have drawbacks to equal gasoline’s.
Still, the supply chains for diesel, ethanol and hydrogen are immature. That should change in a few years, as the most important choice for consumers in car showrooms may be what kind of fuel they want to use.
“Buying a car is not going to be about color choices or automatic versus manual transmission,” said Allen Schaeffer, the executive director for the Diesel Technology Forum, a trade association. “It’s going to be about getting into a powertrain.”
Here is a status report on the alternatives…
