Liker heller BMW´s valg av miljø biler....
Hydrogen will replace petrol. That is the BMW CleanEnergy idea. However, since hydrogen fuelling facilities are not widely available at the moment, the BMW CleanEnergy vehicles are fitted with a petrol tank in addition to the hydrogen tank. If one of the tanks is empty, the vehicle automatically switches to the other. This what is known as bivalent and it is the decisive advantage for the fast introduction of hydrogen vehicles.
BMW 745h study, built in 2001, illustrates what is possible: a dynamic bivalent 4.4-litre 8-cylinder-V-engine for liquid hydrogen or petrol. The performance figures are convincing: output 135 kW and a top speed of 215 km/h (135 mph) at a range of approx. 300 km (180 mls) in hydrogen drive plus 650 km (400 mls) in petrol mode. Hydrogen in the internal combustion engine - this is the future.
