Hydrogen city-car set for UK manufacture

[font size=4]A two-seater hydrogen car designed for local driving is to be built in the UK.[/font]
[font size=3]…
It will be capable of travelling at up to 60 miles per hour, with an energy efficiency equivalent to 240 miles per gallon.
The car, which is being designed by Chris Reitz, previously design director at Fiat and Alfa Romeo, is equipped with an electric motor in each wheel to recapture energy from braking. The energy will be stored in a bank of super-capacitors to provide 80 per cent of the power needed for acceleration.
This means the fuel cell itself can be much less powerful, with an output of 8kW compared to the 85kW devices used in most prototype hydrogen cars, said Hugo Spowers, technical director and founder of Riversimple.
Consequently, the fuel cell will be much lighter, and with no gearbox or transmission system, the overall weight of the powertrain will be significantly reduced, said Spowers. “If the whole powertrain is lighter you can also have a much lighter structure, which has a knock-on effect in reducing the amount of power you need,” he said.
