The LCA model developed in this task will make use of the existing model from the previous HyFLEET:CUTE project. The model includes fuel production, bus manufacturing, bus operation and the end-of-life of the bus.
The extended LCA model will be used to benchmark the deployed H2/FC bus systems with conventional drive train technologies (Diesel Euro 5/EEV and CNG). Here the focus is given to the fuel consumption and emissions data of the analysed technologies and lifetime of drive train components under the operational boundary conditions of CHIC. Beside hydrogen and conventional diesel fuel, biodiesel from biomass gasification, and hydrated vegetable oil (HVO) will be analysed.
Other conventional bus alternative drive trains such as purely battery powered buses and hybrids will also be considered, especially purely battery powered electric buses which are capable of zero emission operation. Special attention here is to be given on reliable and comparable consumption data. Since availability of such data is currently rather limited, support from experts of the participating manufacturers will be given. The analysis will also include trolley buses.
By means of scenario analysis the LCA model developed will allow evaluation of the improvement potentials of hydrogen and FC technology compared with other drive train technologies for public transport buses.
Following the 2009 implementation plan of the JTI, the life cycle modelling will be carried out in accordance with the guidance document developed in the resulting project of the call SP1-JTI-FCH.2009.5.5 (Life Cycle Assessment). This will be in line with and built upon the International Reference Life Cycle Data System (ILCD)
The ILCD format has already been used in HyFLEET:CUTE to provide 7 datasets on different hydrogen supply pathways.
