Abstract

Abstract: In the present study, life cycle energy consumption, efficiency and greenhouse gas (GHG) emissions of Jatropha-based biodiesel was analysed by life cycle analysis method using GREET (Greenhouse Gases, Regulated Emissions, and Energy Use in Transporta­tion) model. This study quantitatively explicates the life cycle energy saving and GHG emissions of Jatropha-derived biodiesel. The functional unit was defined as 1 mile distance driven by the vehicle and the fuel blend was about 20%. The results indicated that Jatropha biodiesel production and its usage in India have positive environmental performance at the current technical levels. Well-to-pump energy efficiency of Jatropha biodiesel production was found to be 75%. As compared with that of gasoline fuel, the use of 20% blended Jatropha biodiesel leads to the reduction of GHG emission about 22.3% and brings about energy saving 9%. Further improvement of production technology would reduce emissions and increase the energy saving markedly.
