Hydrogen bus in Hamburg - Click above to watch video after the jump
The ongoing debate between hydrogen advocates and supporters of battery-powered vehicles has kind of died down for now, but this latest video of the Hamburg hydrogen bus fleet might whip it up again. The video explains some of the well-known advantages and disadvantages of each technology and it also touches on the dirtier side of going green. There's some one-sidedness, such as when the discussion turns to the high costs of fuel cell technology and the inherent lack of energy efficiency of hydrogen vehicles, but it's still an interesting piece to watch.
The gist of the video is pretty simple: hydrogen is expensive, but it can be green; battery power is cheap, but unlikely to be as clean. The video also features the hydrogen-powered buses that roam the roads of Hamburg. As it turns out, those buses get their hydrogen fuel with a little help from the wind and emit nothing but water. How much cleaner can it get? Follow after the jump to watch the bus in action and to get your daily dose of hydrogen versus electric.
