  4. 18. Centralised Distribution Grid Energy Storage Systems : Placement and Utilisation for Grid Expansion Deferment

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Sebastian Andersson; [2018]
    Nyckelord :;

    Sammanfattning : Following an ongoing change towards an increasingly renewable power generation system Swedish grid operators are facing several challenges in coming years. As authorities plan for the decommissioning of nuclear power an increased reliance on de-centralised energy sources such as photo-voltaic distributed generation (PVDG) is expected. LÄS MER

  5. 19. Integrating vanadium redox flow batteries with large-scale wind power

    Master-uppsats, KTH/Energiteknik

    Författare :Axel Heilborn; Fredrik Liljehov; [2018]
    Nyckelord :;

    Sammanfattning : Vanadium redox flow batteries have, in previous studies, shown to have great potential for large-scale energy storage applications. Due to their beneficial characteristics, such as long lifetime, safety and flexible sizing the technology could be used for several different applications. LÄS MER

  7. 20. Estimating the Potential Life Cycle Environmental Impacts of Current and Future Electric Passenger Cars

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Michael Samsu Koroma; [2018]
    Nyckelord :Electric cars; plug-in hybrid; life cycle assessment; ReCiPe indicators; environmental performance; Elbilar; plug-in hybrid; livscykelanalys; ReCiPe-indikatorer; miljöprestanda;

    Sammanfattning : The road transport sector is heavily dependent on fossil-fuel based technologies, and as a result, contribute a significant share towards climate change and other environmental problems. If the transport sector is to reduce its adverse impacts on climate change, then it requires a global shift towards low-carbon technologies. LÄS MER
