6. Reducing cost and CO2 emissions in the gasoline to electric vehicle fleet transition
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/ElektricitetsläraSammanfattning : 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
7. Manufacturing batteries of the future : Critical challenges and undertakings to create the next generation energy storage
Kandidat-uppsats, KTH/ProduktionsutvecklingSammanfattning : In today's world, a dominating piece of news is the global race for large-scale production of Lithium-ion batteries (LIB). LIBs are important because they have become the most widely used type of rechargeable battery in modern electronic devices, such as smartphones, laptops, energy storage systems, and electric vehicles.

8. Numerical modeling of airflow on the cathode-side of a bipolar flow plate : How the formed geometry affects the pressure drop and flow distribution in a hydrogen fuel cell
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Climate change and rising temperatures is a well-known problem. To tackle global warming a transition from fossil fuels to renewable and reliable energy sources is necessary. Hydrogen, in fuel cells, is proposed to replace diesel and gasoline in the transport sector. LÄS MER
9. Research on the Hydrothermal Conversion of Xylose Catalysed by CO2-H2O into Furfural
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Agricultural waste treatment and carbon dioxide emissions from fossil fuel combustion have been critical challenges for sustainable development. This work is part of a study on converting straw into biofuels, which involves using xylose as the material, carbon dioxide (CO2) as the catalyst, and water (H2O) and Gamma-Valerolactone (GVL) as the solvent to produce furfural through hydrothermal conversion.

10. Biltåg i Sverige : Förutsättningar för inrikes biltågstrafik
Master-uppsats, KTH/TransportplaneringSammanfattning : Svenska riksdagen har beslutat att växthusgasutsläppen från inrikestransporter ska minska med 70%mellan 2010 och 2030. Inrikestransporter står för drygt en tredjedel av Sveriges totala utsläpp avväxthusgaser och vägtrafiken står för 90% av utsläppen inom inrikestransporter, där en betydandeandel av vägtrafikutsläppen är från personbilstrafik.
