Hydrogen-powered trucks and vans could soon become a reality, thanks to a British technology company. ITM Power, based near Saffron Walden, Essex, has unveiled a converted Ford Focus, which runs on hydrogen, but can switch back to petrol if the hydrogen supply is exhausted.

The firm has also developed a home refuelling station, capable of producing the gas from water and electricity. ITM's demonstration vehicle, which has completed successful urban commuting trials, can travel 25 miles

An ITM spokesman says: "Although the initial demonstration vehicle is a car, vans and trucks will also be able to use the new fuel system to give CV operators huge potential cost savings on delivery journeys, as well as further reducing CO2 emissions
