>> [ music ] Hi this is Martin LaMonica with CNET. I'm in a hydrogen powered car, it's actually a bi-fuel car, it can run on gasoline or hydrogen. It's a BMW 7 series, they call it a transition technology that will run on hydrogen and gasoline. Now I'm gonna give this thing a spin by pressing start. It's a coast to coast road show for hydrogen. The 2 week long hydrogen road tour started at Portland Maine on August 22. This entourage of fuel cell vehicles have run on hydrogen. The first stop on the 18 state tour was Billerica Massachusetts, sight of the state's first hydrogen fueling station.
>> Alright! [ applause ]
>> There are many technical challenges to mass produced hydrogen fuel cell cars including storage and producing fuel cleanly. Hydrogen cars emit water vapor as exhaust and the fuel can be made in a variety of ways, and it's a quiet ride. ^m00:01:01 [ car sounds, driving ]^m00:01:11
>> And we're ready to go!
>> Your car is on?
>> No put - put?
>> Oh no, not at all, just that whine.
>> Roberto Cordaro, the CEO of fuel cell company Nuvera, predicts that fueling stations will link to more hydrogen cars.
>> If you have an analogy to the hybrid car, for instance the Toyota Prius, it was introduced on generation one in 1997. In eleven years went through 3 generations and now is mass produced. If you think along the same lines, it's the same the automotive industry will do with fuel cell cars. If you look at these cars will be first generation now, second and third generation will be needed before they really move to mass production in terms of hundreds of thousands to millions a year.
