Great spots 11 - hydrogen-powered bus in Hamburg

Saw this on my trip to Hamburg last week. There are a number of these operating in the centre of the city - the stuff coming out of the exhaust is just steam, so local pollution is minimal.


I'm a bit hazy about hydrogen engine technology, but I think this is a fuel cell vehicle, rather than one that takes the BMW approach of using hydrogen in a normal combustion engine, which, as I discovered when I drove the company's Hydrogen 7 model earlier this year, is more or less indistinguishable from the standard product, at least from a driving point of view.
