An indigenously developed hydrogen fuel cell bus developed by the Council of Scientific and Industrial Research (CSIR) and KPIT Limited has been launched in Pune.
The fuel cell utilises hydrogen and air to generate electricity to power the bus, whose only effluent is water, thereby making it possibly the most environment-friendly mode of transportation. A single diesel bus plying on long distance routes typically emits 100 tonnes of CO2 annually and there are over a million such buses in India. Hydrogen fuel cell vehicles provide excellent means to eliminate on-road emissions in the sector.
