    Although it’s hard to say whether or not fuel cell vehicles (FCVs) will eventually work out as a viable environmental solution, there’s little doubt that even today FCVs are a good bit greener than most similarly sized gasoline vehicles. A an eco-rating of the Honda FCX Clarity shows that it cuts pollution by nearly half compared to a standard midsize car (see http://autoecorating.com/how-does-hydrogen-compare/). And that’s with hydrogen made from natural gas and counting the energy losses mentioned in article above.

    That being said, hydrogen fuel cell cars still face lots of obstacles. They also face stiff competition from ongoing improvements in gasoline vehicles, including grid-free hybrids such as the Toyota Prius that will offer a much more affordable path to carbon reduction for at least a few more decades. So it’s a bit much to say that “Hydrogen is the key to sustainable transportation …” It’s just one among several promising options that are worthy of continued research but which are not yet ready for prime time.
