| dc.description.abstract | The aim was to cover knowledge gaps and extend the knowledge base for the environmental impact of two electric vehicles by conducting an attributional Life Cycle Assessment (LCA) where two vehicle options, a Battery Electric Vehicle (BEV) and a Fuel Cell Electric Vehicle (FCEV), were compared. The thesis was conducted in collaboration with the company PowerCell Sweden AB. The research question was: What are the environmental impacts of an FCEV powered by PowerCell’s MS-100 system and how does this vehicle compare with a BEV powered by a Li-ion battery with the same: powertrain performance, payload, driving range and total lifetime? To answer the research question an LCA case study was conducted. The study investigated four technology options, where the vehicle options were analysed with two production pathways each for the energy carrier for propulsion. The BEV was powered by either European- (RER Mix) or Swedish electricity mix (SE Mix). The FCEV was powered by hydrogen from either steam methane reforming (SMR) or wind powered electrolysis (WP-Electrolysis). The data for driving range and electricity/ hydrogen consumption were obtained from simulations in the simulation tool FASTSim and were used as Life Cycle Inventory (LCI) data. The data for the LCA case study was moreover obtained from literature studies and data collection at the company PowerCell. Additionally, a sensitivity analysis was conducted to check the robustness of the Life Cycle Impact Assessment (LCIA) results. Two parameters were investigated, the platinum content in the MS-100 system and the driving range. The environmental impacts were evaluated for seven impact categories. The LCIA results indicated that the technology options with a high share of renewable energy sources, BEV-SE Mix and FCEV-WP Electrolysis, were the preferred choices. However, for the chosen driving range the BEV-SE Mix was the most environmentally benign technology option. The thesis was concluded with recommendations for the FCEV and MS-100 system. To be an environmentally friendly option, the FCEV should be used for extended driving ranges and should be fuelled with renewable hydrogen. For the MS-100 system, it was shown that platinum was a large contributor to the environmental impact for several of the considered environmental problems. Important environmental improvements would be to either recycle or reduce the amount of platinum. | sv |
