Investigation of released CO2 and consumed energy for two different usages of electrified vehicles of various levels, operating in service situations

Electric power engineering (MPEPO), MSc
This report aims to study the possible implementation of electrified vehicles in two specific but differently demanding service situations; Hemtjänsten & Flexlinjen. The study included not only different petrol mixes with ethanol; 95% and 90% petrol, but also several electricity mixes where the denotation Worst symbolises Scandinavian Electricity mix and Ultimate is what could be produced in the future (100% hydro power). The study reveals that the more electricity used the less CO2 emissions (g/km). If using a hybrid electric vehicle in Hemtjänsten instead of a fuel operated vehicle the reduction of CO2 emissions is more than 41%, a remarkable save of more than 1000 kg of CO2 per year. If Hemtjänsten instead would use a battery electric vehicle the reduction would be almost 50% even considering the, for Sweden, worst possible electricity mix with burning fossils. There is an almost 90% reduction in CO2 emissions (more than 2000 kg/year) for the upper range of Sweden’s electricity median. For Flexlinjen, the gains are similar, although proposed emission level regulations will be harder to lie under.
