Hydrogen powered Black Cab hits London streets

The first LTI TX4 hydrogen-powered London Taxi A hybrid fuel cell electric London cab has been revealed, but unlike recent developments with the traditional Black cab – where Mercedes are busy taking over - this experimental hydrogen-powered Cab is based on the familiar LTI TX4. The joy of using a hydrogen tank to run the batteries is that unlike a plug-in hybrid a refuel will take all of five minutes – no more than filling up with petrol or diesel would, A full tank will give a range of around 250 miles and – just like a plug-in BEV – the hydrogen powered cab is emission free at the point of use. The plan is to raise funding to produce a fleet of hydrogen powered Black Cabs in time for the London Olympics in 212.
