There's never one around when you need one.
Mazda said the RX-8 Hydrogen RE, based on its popular RX-8 sports car, gets around these problems by running on gasoline in the absence of a hydrogen fueling station, and using existing engine parts and production facilities to lower costs.
The car is powered by Mazda's iconic rotary engine and can switch between hydrogen and gasoline fuel with the flick of a switch. It can cruise for a maximum 62 miles on hydrogen and 341 miles on gasoline it said.
Fuel cell cars, meanwhile, use hydrogen to first generate electricity through a fuel cell stack for power, and require an electric motor.
A rotary engine is suitable for hydrogen fuel because the separate chambers for fuel intake, combustion and exhaust significantly reduce the danger of the fuel's backfiring compared with a conventional engine. . .
Japan has 13 state-owned hydrogen fueling stations, while energy-related companies such as Idemitsu and Iwatani also own their own fueling facilities.
Ford Motor Co. owns a controlling interest in Mazda.
They need to get the range up to about 150 miles or so. Electric cars have trouble with range too. People need to stop every 2 or 3 hours since the seat cushions will only hold so much.
