Energy and Environmental Benefits of Rapeseed Oil Replacing Diesel

Malça, João, Freire, Fausto·2009·International Journal of Green Energy

Abstract

In this paper the benefits of rapeseed oil (RO) replacing petroleum diesel in transportation are evaluated, demonstrating that RO use displaces greenhouse gas (GHG) emissions and saves fossil energy. A systemic description of the RO chain in France has been implemented and GHG emissions and energy used throughout the life cycle have been calculated using alternative co-product credit procedures, namely a replacement method, three allocation approaches (mass, energy, economic) and ignoring co-product credits. The results show that the cultivation stage is particularly important, being responsible for 68% of the primary energy requirements and 87% of the GHG emissions of the RO “well-to-tank” system, mainly due to the use of fertilizers and related N2O emissions. Considerable reductions in fossil fuel depletion and GHG emissions can be achieved by replacing petroleum diesel with rapeseed oil (0.9 MJ and 62 g CO2eq per MJ of fossil diesel replaced), but optimum use of co-products is needed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
