  1. 1. Linear optimization of a potential microgrid to supply TSK70

    Master-uppsats, KTH/Kemi

    Författare :Roy Satis; [2023]
    Nyckelord :modelling; solar power; energy storage; electric vehicle; construction site; modelering; solkraft; energilagring; elektrifierad fordon; konstruktionsplats;

    Sammanfattning : Transport- och byggindustrin är en bidragande orsak till klimatkläget på grund av den betydande mängd växthusgaser som produceras. Att byta till elfordon är en metod för att minska de skadliga effekterna av klimatförändringarna. LÄS MER

  3. 2. Kartläggning & optimering av externa flöden ur ett hållbarhetsperspektiv : En fallstudie på Gestamp HardTech

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Malin Norgren; Elin Lindberg; [2023]
    Nyckelord :Sustainable transport; Vehicle emissions modeling; Truck emissions; Vessel emissions; Train emissions; Air pollution modeling; Future vehicles;

    Sammanfattning : In the pursuit of sustainable development, the transportation sector plays a crucial role by significantly contributing to greenhouse gas emissions. The purpose of this study is to examine how companies utilizing third-party logistics can compile and reduce transport-related emissions, more specifically investigating short- and long-term opportunities for the external flow of Gestamp HardTech in Luleå.

  4. 3. Vehicle to Home and Vehicle to Grid : a study and modeling of the technical system when charging and discharging electric vehicles for households with PV systems

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Christine Timm; [2023]
    Nyckelord :electric vehilce; EV; bidirectional charging; smart charging; smart charging algorithms; optimization; PV;

    Sammanfattning : As the world undertakes global climate goals to lower the emissions of greenhouse gases, more renewable energy sources are introduced in the electrical energy system, and fossil fuel driven combustion engines aims to be replaced by electric vehicles. New problems connected to the transition such as voltage fluctuations, production and consumption mismatch and high peak loads, requires new solutions. LÄS MER

  5. 4. When is Electric Freight Cost Competitive? : Computational modeling and simulation of total cost of ownership for electric truck fleets

    Uppsats för yrkesexamina på avancerad nivå, Linköpings universitet/Institutionen för ekonomisk och industriell utveckling

    Författare :Anton Zackrisson; [2023]

  7. 5. Modeling and Evaluation of High Temperature PEM Fuel Cells for Truck Applications

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Johannes Wrangstål; Marcus Ögren; [2022]
    Nyckelord :Modeling; Fuel Cell; FCHEV; HTPEM; LTPEM; ECMS; High temperature proton exchange membrane;

    Sammanfattning : With increasing demands on lowering carbon emissions, fuel cell hybrid electric vehicles (FCHEV) have been seen as an alternative to the fossil-fuel driven trucks of today. These would have less emissions and strive to have the same range as any diesel driven transport vehicle. LÄS MER
