Abstract

This paper presents the results of the evaluations conducted on the alternative pathways considered in net energy analysis of Jatropha press-cake utilization as biofuel feedstock. Biogasification and thermal gasification are the two alternative pathways specifically being considered in this particular study. An Energy Return on Investment (EROI) was introduced in this study as the primary tool for net energy analysis respectively. EROI was able to further evaluate the economic variability and potentials of utilizing Jatropha press-cake as the feedstock for generating renewable biofuels. The by-products of the two alternative pathways being evaluated is not yet considered in this study. However it is highly recommended for future research that by-products must be considered in net energy analysis.
