Most of the media buzz in the past few months has been about electric cars and hybrids. Yes, they offer plenty of advantages over petrol cars, but so do hydrogen cars. Hydrogen's only emission is water, if it is made from a non-polluting renewable resource. So where are the hydrogen cars?
Well, they are coming, and sooner than you might have thought. Hyundai has announced that starting in 2012, it will sell 500 hydrogen cars, ramping up production annually after that. That beats most of its competitors to the finish line. Is it too good to be true?
