ABSTRACT
In several our publications energetic efficiency of biofuel production was defined as a ratio of the amount of energy obtained in a form of biofuel to the sum of energy contributions necessary to conduct production processes on all the production stages. It was also shown that such a definition enables subsequent inclusion of production steps due to additivity of reciprocals of energetic efficiency determined separately for each step. In the present work, several scenarios of the transport of biomass between plantation and industrial facility converting biomass into biofuel are considered, appropriate values of energetic efficiency are computed and compared. The analysis is confined to biodiesel production based on rapeseed. The results show substantial differences caused by various approaches to that stage of transport.
