For a developing country like India, meeting energy needs (mainly in the form of electricity and transportation fuels) in various sectors such as agriculture, industrial and transport is vital to achieve sustainable growth and economic development. The electricity generation in India is dominated by coal-thermal route [1]. Although the total installed capacity for electricity generation is 148 GW (as on February 2009), it is far insufficient to meet the needs of the population [2]. Moreover, supply of electricity to remote regions and hilly terrains (especially in the northeastern states) is difficult as extension of grid to these places is impractical. The transmission losses are as high as 30% and fluctuations in voltage are beyond acceptable limits [1,2]. Therefore, there is an urgent need to utilize and promote renewable energy sources in order to make these regions independent from grid supply [3]. Various options for decentralized electricity generation through renewable sources include biomass gasification, solar, wind and small hydro. However, from Indian perspective biomass gasification is the most feasible option among these for various reasons [4-9]: (1) biomass is
