1. 11. Reducing cost and CO2 emissions in the gasoline to electric vehicle fleet transition

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Emil Grund Stålvinge; [2023]
   Nyckelord :electric car; electric conversion; bldc; li-ion; lion; lipo; li-po; volvo; elbil; elbilar; elkonvertering; bldc; li-ion; lion; lipo; li-po; volvo;

   Sammanfattning : If you buy a new electric car today it will take on average about ten years for you to start saving money compared to just continue driving your old gasoline car. It will also take about 4 years until you start saving carbon dioxide emissions, both of this is because of new production costs and emissions. LÄS MER

3. 12. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Adam Jacobsson Trönndal; [2023]
   Nyckelord :Fuel cells; Phosphoric acid; Polybenzimidazole; PA-PBI; Ionic liquid; IL; High temperature proton exchange membrane fuel cell; HT-PEMFC; Electrochemical impedance spectroscopy; EIS; IL-PBI; Chemical engineering; Technology and Engineering;

   Sammanfattning : In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. LÄS MER

4. 13. Decarbonisation of service vessels in offshore wind power through power-to-X self-sufficiency

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

   Författare :Clemens Kellander; Ludvig Fredriksson; [2023]
   Nyckelord :Alternative fuels; compressed hydrogen; battery; production; energy storage; operation and maintenance; O M; offshore; wind power; service vessel; crew transfer vessel; CTV; service operations vessel; SOV; decarbonisation; global warming potential; life cycle; Technology and Engineering;

   Sammanfattning : This report examines the possibilities of decarbonising operation & maintenance vessels for a prospective floating offshore wind power park at the Utsira Nord site in Norway, through self-sufficient energy carrier production utilizing power-to-X-solutions. Possible alternative fuels are identified as compressed hydrogen, batteries, liquid hydrogen, ammonia, methanol, and biofuels, out of which the former two are the subject for thorough investigation in this report.
