India has unveiled its first indigenously developed hydrogen fuel cell bus in Pune which has been rolled out by the Council of Scientific and Industrial Research (CSIR) in association with a private firm called KPIT Limited.
Fuel cell vehicles utilise a mixture of air and hydrogen to produce electricity, which runs the vehicle. Having said that, water is the only effluent from the bus. Therefore, FCEVs (Fuel Cell Electric Vehicles) are the cleanest, greenest and most environment-friendly mode of public transportation.
The running cost of the hydrogen fuel cell vehicles is even lower than the diesel ones while the latter are responsible for air pollution for upto a huge extent. Reportedly, nearly 12-14 percent of CO2 emissions is caused by heavy vehicles with a diesel engine. On the other hand, FCEVs boast of a zero green-house gas emissions.
