A team at the Lawrence Livermore National Laboratory have revealed a potential revolution in hydrogen cars, after driving 650 miles on one tank of liquid hydrogen. In a recent test, the scientists set a new world record after they installed a super-insulated hydrogen gas tank in a standard Prius hybrid that was able to keep a full load of the liquid without evaporating for six days.

The tank, weighing in at around 300 pounds, removes a heck of a lot of obstacles to the advancement of hydrogen-powered cars. Current versions, such as the fleet of hydrogen-electric Toyota Prius’s used by various city governments across Southern California, run on compressed hydrogen gas, and have a limited range of around 80 miles between refuels. Even a pretty unambitious three-gallon tank fills the entire trunk of a Prius, yet still only enables a range of approximately 200 miles, not really enough to compete with gasoline-only vehicles.

300 garbage collection trucks in California will soon be fueled by the same trash that they haul. Landfill gas will be purified and liquefied, producing up to 13,000 gallons of liquefied natural gas (LNG) daily.

This facility at Waste Management’s (WMI: NYSE) Altamont Landfill in Livermore, California will begin operation in 2009. It comes with a price tag of $15.5 million, with grants providing $1.4 million.
