Your future fuel tank

GM contracts Quantum Fuel System Technologies to provide high-tech hydrogen tanks for its new Equniox fuel cell cars.

We reported earlier on GM's news that it plans to put the new Equinox fuel cell car on the road next year. Green Car Congress has a story about GM signing up Quantum Fuel Systems Technologies Worldwide as its hydrogen fuel tank supplier. GM's 100 planned Equinoxes will get Quantum's tanks, which are made of lightweight materials and can hold 10,000 psi of pressure. The tanks come with valves that monitor pressure and have safety cutoffs, which would be activated if a crash is detected. Each Equinox will have three tanks, holding 9.25 pounds of hydrogen. That's right, in the future we'll be measuring our fuel by the pound, not by the gallon.
