Anyone know if these cars are liquid hydrogen or compressed gas H2? Also, how are they fueled, e.g. where are the fueling stations? Danny |

@tornado.texas.rr.com: http://www.msnbc.msn.com/id/16115734/site/newsweek/ Anyone know if these cars are liquid hydrogen or compressed gas H2? I believe there have been examples of both kinds. Also, how are they fueled, e.g. where are the fueling stations? 'Fill 'er up' on H2 is still a long way off. LH2 fueling is very unlikely, it's almost certainly got to be compressed gas to be at all feasible. My bet is that hydrogen will NEVER be a viable fuel, for a variety of reasons. --Damon |

Damon's probably right. Hydrogen burns hotter than gasoline which leads to even higher production of NOx. That is, unless there is also a tank for pure O2 as the oxidizer, and by that point the costs are really going sky-high. Tim |

Considering the problems with H2 production and storage why are we even trying. If air/H2 pollutes the program is dead. How about Air - H2 fuel cells? Do they produce NOx?

Because we are going to have to do something other than petroleum eventually. If air/H2 pollutes the program is dead. Fortunately, there are several technical approaches to dealing with this.
