Biogas and Fuel Cell as Vehicular Fuel in India

There is a worldwide concern due to the fact that the rate of consumption of fossil fuels by far exceeds the rate of their formation. This has stimulated researchers to look into economically viable and more environmentally friendly alternatives such as biogas, fuel cells, etc. Development of technologies for utilisation of such fuels for the transport sector is in rapid progress worldwide. Utilisation of biogas is quite popular as cooking fuel in rural India and China. Various efforts were also made on utilisation of biogas as vehicular fuel in India. In this chapter, a review on various factors influencing the performance of biogas digester and functionalities of fuel cells and its application as vehicle fuel has been discussed.
