Hydrogen-Powered Prius Travels 650 Miles on One Tank

A Toyota Prius hybrid retrofitted to run on liquid hydrogen by researchers at the Lawrence Livermore National Laboratory has traveled 650 miles on one tank. The researchers have designed a cryogenic tank without the typical boil-off problem as is present in other current low temperature liquid hydrogen tanks.

The cryogenic tanks hold 150 liters of LH2 (liquid hydrogen) and are made of carbon fiber that envelops an aluminum lining. The tank can store either liquid or compressed hydrogen gas similar to the BMW cryogenic tank breakthrough I had talked about back in April this year. BMW’s super-cooled cryo-compression tanks were tested in a mono-fueled Hydrogen 7 luxury car that actually cleaned the ambient air surrounding the vehicle.

According to Livermore researchers, compressed hydrogen is better utilized by the Prius on short trips (and is less expensive) and liquid hydrogen is ideal for longer trips. The Livermore tank is also safe as it has been burned, drop tested, and shot with bullets without incidents of fire or explosion.

One of the myths about hydrogen vehicles has been that they don’t have the range of today’s standard vehicles. That myth was exposed last November when Toyota proved that their FCHV had a range of 485 miles. Now, on World Environment Day, the myth is once again trounced by the 650-mile hydrogen-powered Prius.

  1. Can we run our car with water and gas?
    Can anybody tell me is the HHO Gas is real working or is another scam?

    Electrolyzing water to create hydrogen and oxygen and then running this through an internal combustion engine to supplement the gasoline or diesel fuel is real, proven technology.

    According to this news the car will run 650 Miles on 150 Liters of LH2 so that translates into 650 Miles with about 39.6 Gal of LH2 giving an efficiency of 16.41 Miles per Gal. That’s too low… my math must be flawed here. (?)

    Will 150 liters in gas be equivalent to 39.6 Gal? Will the Miles per Gallon efficiency and cost change when stored in gas compared to when stored in Liquid form?

    I had gotten some of the information from this article

    http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2008/06/05/BAMJ112TQ8.DTL

    but I agree that the numbers do sound low on an MPG basis. I haven’t been able yet to find other resources that mention the 150 liter capacity of this tank so this number could be flawed.
