Hydrogen fuel cell black cab unveiled in London

A new emissions free version of the iconic black cab has been unveiled in London today by the deputy mayor.

The prototype is said to look and drive just like a normal cab, but is powered by a hydrogen fuel cell system that only emits water vapour.

The vehicle is the result of a partnership between Intelligent Energy, London Taxis International, TRW Conekt and Lotus Engineering. It is reportedly capable of 80mph and has a 250 mile range.
