    Sammanfattning : Background Nuclear reactors utilizing molten fuels rather than solid fuels show a massive advantage in energy yield, waste handling and safety features. The only successful reactor utilizing a molten fuel was called the ‘Molten Salt Reactor Experiment’ (MSRE), built and operated in the Oak Ridge national laboratory (ORNL) in Tennessee, U.S.A.

  4. 4. Operation strategies of using energy storage for improving cost efficiency of wind farms. : Examining emergency power supply and support services.

    Master-uppsats, Uppsala universitet/Elektricitetslära

    Författare :Philip Lundquist; [2021]
    Nyckelord :Hydrogen energy storage; Hybrid energy storage; Support services; FCR-N; Emergency power supply;

    Sammanfattning : With the increase in the world energy demand and environmental incentives, renewable energy sources (RES) need to determine their place as some of the primary power sources in future power systems. However, due to uncertain energy production, renewable energy sources cause unbalance in the power system due to the unsynchronized supply and electricity demand. LÄS MER

  5. 5. Study of the vibronic mixing in chlorophylls with multidimensional spectroscopy

    L3-uppsats, Lunds universitet/Kemiska institutionen
