Extended “well-to-wheels” assessment of biodiesel
for heavy transport vehicles (BioHeavy) Reference:
PTDC/SEN-TRA/117251/2010 Project Objectives The project has the
following specific objectives: • To select relevant biodiesel systems and to develop a
consequential LC inventory modeling framework of biodiesel, in which consideration
of land use change (LUC) and/or indirect land use change (ILUC) is crucial
for a comprehensive sustainability assessment. • To perform a comparative attributional and consequential
WtT modeling of the selected biofuel systems, to assess
and discuss the differences in the results, and to make results transparent
and comparable with other LC studies published in the literature, which have
usually adopted an attributional approach. • To develop and implement a robust experimental TtW framework integrating three complementary approaches:
fleet data assessment, on-road and engine dynamometer testing to perform an
experimental characterization of emissions and energy performance of heavy
transport vehicles, fueled with different biodiesel blend. • To improve the TtW
performance of heavy vehicles engines fueled with various biodiesel blends. • To identify the major sources of uncertainty in the
extended WtW assessment of biodiesel systems and
the main procedures to reduce this uncertainty, recognizing that results of a
LC study can be affected by parameter uncertainty and variability and by
scenario uncertainty. • To make a multi-criteria assessment of biodiesel system
alternatives, combining LCA and MCDA and addressing/managing uncertainty. • To compare the relative merits of biodiesel and
petroleum diesel, taking into account the new sustainable criteria defined in
the RED and Fuel Quality Directives (EC09), as well as the new EU guidelines
for land carbon stock calculation (2010). To carry out this project,
we gathered a multidisciplinary research team with large and diversified
experience in LC modeling and assessment of biofuel systems, GHG emissions,
and other environmental impacts (ADAI-LAETA; Brandão
IES-JRC EU, Italy); in the experimental TtW
characterization of the environmental and energy performance of vehicles
engines, including dynamometer tests, on-road testing, and fleet data
analysis (ADAI-LAETA) and with a strong background in the field of MCDA
(INESCC) and diversified experience in uncertainty analysis (ADAI-LAETA;
INESCC). Research Team Principal
