Despite tough competition with cellulosic biofuels, clean diesels, and plug-in gas-electric hybrids, hydrogen is steadily emerging as a future fuel.
But even this early - and with only a few dozen fueling stations across the country - eight automakers this week are flaunting their R&D departments with a 31-city "Hydrogen Road Tour" co-sponsored by the US Department of Energy. Most of the cars are rolling research labs, but a few are in limited production.
The tour started in Portland, Maine, yesterday (as US Senator Olympia Snowe, R-Maine, looked on) and will stop in Billerica and Cambridge, Mass., as well as Wallingford, Conn., before finishing in Santa Monica, Calif., next week.
