    University essay from Uppsala universitet/FREIA

    Author : Elias Waagaard; [2020]
    Keywords : Cryogenics; Liquefaction; Helium;

    Abstract : The thermodynamics inside the helium liquefier in the FREIA laboratory still contains many unknowns. The purpose of this project is to develop a theoretical model and implement it in MATLAB, with the help of the CoolProp library. READ MORE

  5. 4. Evaluation of liquid air as an energy storage alternative

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Tomas Högberg; Martin Tholander; [2018]
    Keywords : Liquid air; LAES; Energy storage; efficiency; Flytande luft; LAES; Energilagring; verkningsgrad;

    Abstract : As renewable, intermittent energy sources are expected to increasingly replace fossil based energy, energy storage technologies are crucially important in achieving the goal of fossil free energy, a cornerstone of sustainable development. Liquid air energy storage (LAES) is a novel technology that liquefies air when excess electricity is available. READ MORE
