Scientists at the Lawrence Livermore National Laboratory have revealed that they have driven a car 650 miles on one tank of liquid hydrogen. In a recent test, the team 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, setting a new world record.
The 300-pound tank removes a lot of obstacles to the development of hydrogen-powered cars. Current versions, such as the fleet of hydrogen-electric Toyota Prius’s used by various city governments across
Speaking about the breakthrough, Livermore Lab engineer Salvador Alceves said, “We think if you have the cars, and the technology for the cars, the infrastructure will follow. The cars are the hard part.”
The tank can also hold less expensive compressed hydrogen, enabling users to use it for shorter journeys with the option of switching to liquid to triple their range for longer drives. It can also withstand crashes and fires without exploding. The team apparently even shot one tank with a gun without blowing it up – that must have been an exciting day at the office!
Livermore Lab estimates that we could see prototype cars in 2012. Lead technician Tim Ross said, “We will get there, I truly believe I will see this in my lifetime.”
