city will have a fleet (more than 10) of public vehicles--buses, or taxis, or garbage collection or police or whatever--powered by hydrogen.    As I see it, the major hurdles with hydrogen powered vehicles are: 1) Developing a fuel cell that will be cheap enough to mass produceand sell.    Given current levels of investment and the prospect of future oil price shocks, technological advances will make fuel cell production affordable in in the next decade.
