Your future fuel tank

Your future fuel tank

We reported earlier on GM's new Equinox fuel cell car that it plans to put 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 cut-offs, which would be activated if a crash is detected. Each Equinox will have three tanks, holding nine and a quarter lbs. of hydrogen. That's right, in the future we'll be measuring our fuel by the pound, not by the gallon.
