Abstract: Biodiesel production from palm oil has been considered one of the most promising renewable resources for transportation fuel in Thailand. The objective of this study was to analyze the energy performance and potential of the palm oil methyl ester (PME) production in Thailand. The PME system was divided into four stages: the oil palm plantation, transportation, crude palm oil (CPO) production, and transesterification into biodiesel. The results showed that the highest fossil-based energy consumption was in the transesterification process, followed by the plantation, transportation, and CPO production. A net energy value and net energy ratio (NER) of 24.0Â MJ/FU and 2.5, respectively, revealed that the PME system was quite energy efficient. In addition, if all the by-products from the CPO production (such as empty fruit branches, palm kernel shells, and biogas) were considered in terms of energy sources, the NER would be more than 3.0. The PME can be a viable substitute for diesel and can decrease the need for oil imports. Based on B100 demand in 2008, PME can be substituted for 478 million liters of diesel. Moreover, with palm oil output potential and B5 implementation, it can be substituted for 1134 million liters of diesel.
