MIT study: Diesel Beats Hydrogen For Green Car Power

An anonymous reader writes "Bummer story on Science Blog for people looking to gas up on the H. Even with aggressive research, the hydrogen fuel-cell vehicle will not be better than the diesel hybrid -- a vehicle powered by a conventional engine supplemented by an electric motor -- in terms of total energy use and greenhouse gas emissions by 2020, says a new MIT study. If we need to curb greenhouse gases within the next 20 years, improving mainstream gasoline and diesel engines and transmissions and expanding the use of hybrids is the way to go."
