  1. 1. Dimensionering av krisberedskap för elbilsladdning : en simuleringsstudie om krisberedskap för samhällsviktiga funktioner

    University essay from SLU/Dept. of Energy and Technology

    Author : Linus Christiansen; [2023]
    Keywords : krisberedskap; samhällsviktig verksamhet; personbilstransport; elfordon; elektrifiering;

    Abstract : With the rising number of electric vehicles in the Swedish vehicle fleet in combination with the rising electricity demand in the country, it begs the question. How should the electricity demand from charging of electric vehicles for vital societal functions be managed in a time of crisis without the support from the electric grid? This study focuses on the task of dimensioning reserve power systems for electric vehicle (EV) charging of parking spaces with 10, 20 and 30 cars. READ MORE

  3. 2. Hydrogen fuel in the domestic maritime transport sector of Fiji : A Feasibility Study

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Tilda Eklund; Anna Fredén; [2023]
    Keywords : Fiji; Fuel Cell; Maritime Hydrogen; Maritime Transport; Fiji; Bränslecell; Maritim Vätgas; Maritim Transport;

    Abstract : The maritime transport sector accounts for around 2.9% of the world’s anthropogenic emissions, a percentage that is growing yearly. Alternative fuels have come to be considered the necessary solution of the future, not least in island nations such as Fiji that are socially and economically dependent on sustainable maritime transport.
