    GM Hydrogen Fuek Cell Car


    Regarding greenness, the Provoq taken by itself is clean as a whistle, emitting only water vapour. However, its hydrogen fuel is effectively a way of storing energy from other sources. At present hydrogen fuel is made by reforming natural gas, a process which releases large amounts of CO2 and is highly inefficient. It would be less carbon-intensive, and considerably cheaper, to simply run vehicles on liquefied gas.
