Life cycle assessment of Biodiesel - Hydrotreated oil from rape, oil palm or Jatropha
Poster (konferens), 2008
There is a need for fuels based on renewable resources that have acceptable emission profiles and that are functional for truck engines used in heavy vehicles. Volvo has participated in the CONCAWE/EUCAR/JRC WTW study, which analyzed a number of candidate fuels, several process routes to produce each fuel as well as different raw material choices. However, the CONCAWE study did not include any second generation hydrogenated vegetable oil type biodiesel. In the present study, Volvo and Chalmers investigate and benchmark hydrogenated vegetable oils. Different production routes from different proposed raw materials are investigated using life cycle assessment modeling. Raw materials considered are oil from rape seed (grown in Germany), palm oil (grown in Malaysia) and oil from the fruits of Jatropha curcas (grown in India). The raw material is converted into hydrogenated oil at a production site in northern Europe and used at the European market. Results regarding life cycle global warming potential and energy use are presented.
