GreenNews - UK - The lighter route to cleaner air
London is spearheading the drive to cut pollution by investing heavily in hydrogen-powered buses. But is there a better way? London,UK -The Guardian, by Sean Dodson -July 20, 2006: -- London has long been known for its poor air quality... Three-quarters of all air pollutants in London come from the roads; so the promise of a new generation of vehicle that leaves no pollution should prove as welcome as an open window on a sweltering day... The first stop on the road to a hydrogen-based economy is being made by the red London bus... a hydro-bus looks exactly like a regular single-decker. But listen carefully: it is barely louder than a milk float. Look closely and you'll notice its only emission is a plume of steam... Soon, up to a dozen buses will be added as London spends tens of millions on its experimental fleet of "hydro-vehicles"... If the test proves successful, London's bus fleet could switch to hydrogen sometime in the next decade... The London mayor, Ken Livingstone, holds high hopes that hydrogen could help create cleaner air and dilute the city's dependence on fossil fuels. If hydrogen can be made and distributed cheaply enough - and in volume - it could, he argues, help make fossil fuels history... (Picture: Hydrogen fuel cell powered London bus -CUTE Program)
