Photos: Green cars of the future

We've seen many hydrogen fuel cell cars at CNET Car Tech and driven many of them as well. Every major automaker has one in the works, and they are the best candidate for replacing gasoline engine cars. Fuel cells generate electricity cleanly, with only water and heat as emissions. Many of the cars shown here are being tested in government and private fleets, getting everyday use on public roads.

Ford Explorer fuel cell vehicle

Ford's newest fuel cell research vehicle uses the Explorer SUV platform. It has two 65 kilowatt motors powering all four wheels. Although the vehicle pictured has 5,000psi tanks, it's slated to get 10,000psi tanks storing 10 kilograms of hydrogen, which will give it a range of 350 miles.
