Battery electric cars like the Nissan Leaf and Chevy Volt count the federal government as a good friend these days. The government has spent two and a half billion dollars in just a few years to boost battery technology.
But there’s another way to propel an electric car– with hydrogen. And proponents are making a last-ditch effort to convince the Obama administration that fuel cell cars are ready for prime time.
Take Honda’s fuel cell electric car, the FCX Clarity. It can go about 240 miles on a tank of hydrogen fuel. About 60 miles to the gallon if you want to compare it to gasoline. The only emission from the car is water so pure you could drink it
(Here's a video of me taking the FCX Clarity for a test drive)
There are emissions from the process used to create hydrogen, from natural gas. But the emissions are about 60% less than comparable emissions from cars using internal combustion engines.
