Why choose hydrogen-based fuel cells as an energy source for vehicles?
GB: Hydrogen is a very clean-burning fuel. It reduces down to water when you run it through a fuel cell, meaning no emissions. It can also be manufactured in a central place then doled out for use. This would allow us to keep any pollution caused by actually generating hydrogen, whatever that method may be, in one location, away from cities and out of the people’s lungs. I find the most important thing that we have to be concerned about is air pollution in our inner cities. There’s a growing need to curb car emissions in cities such as Los Angeles, San Francisco, New York and internationally, places like Mexico City and Kuala Lumpur. The other thing is that fuel cells, like internal-combustion engines, are scaleable to the amount of power you want. In cars today, if you want more power, you get a bigger engine. And if you want to go farther, all you need is a bigger gas tank. Unlike electric cars, whose batteries are good for things like golf carts and small Post Office vehicles, fuel
