The best argument for this type is fuel is that, whilst it doesn't bring down net carbon emissions, it would reduce inner city air pollution, so surely concentrating on Cardiff or Swansea city centres would be a better strategy. The vehicles aren't usually capable of high speeds either, so would be better suited to urban traffic. Though maybe the 'hydrogen highway' thing is just a catchy title. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=351#post-2661 Fri, 12 Feb 2010 13:06:28 +0000 chdot 2661@http://citycyclingedinburgh.info/bbpress/ <p><a href="http://news.bbc.co.uk/1/hi/wales/8511319.stm" rel="nofollow">http://news.bbc.co.uk/1/hi/wales/8511319.stm</a></p> <p>"While some scientists are hopeful of the fuel uses of hydrogen, many others are sceptical because it is inefficient to produce, expensive to transport and to convert into electricity." </p>
