  1. 1. Solar PV Integrated with Seasonal Thermal Storage and District Heating

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Lovisa Thalén; Hannah Ekström; [2023]
    Nyckelord :Solar PV; power-to-heat; heat pump; electric boiler; thermal seasonal storage; district heating; Technology and Engineering;

    Sammanfattning : In order to contribute to reaching the climate goals of the future, power-to-heat (P2H) technologies are a possible solution. A heat pump (HP) or an electric boiler (EB) can be used to produce warm water by utilising cheap electricity from photovoltaic (PV) parks in the summer when there are many hours of sunlight. LÄS MER

  3. 2. Life Cycle Assessment of Borehole Thermal Energy Storage

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

    Författare :Saga Karlsson; [2022]
    Nyckelord :;

    Sammanfattning : Borehole thermal energy storage (BTES) is a technology used to store energy between seasons. It could therefore be a solution to the seasonal mismatch between the use and production of (renewable) energy, which can be used to increase energy efficiency and reduce greenhouse gas emissions.

  4. 3. Comparing the Effects of Flexibility Options on Conventional and Low-temperature District Heating Networks : Studying the potential of the next generation of district energy systems

    Master-uppsats, KTH/Energiteknik

    Författare :Mario Nithyanathan; [2022]
    Nyckelord :District heating DH ; low-temperature district heating LTDH ; 4GDH; Flexibility; Thermal energy storage TES ; Optimization; Modelling; Fjärrvärme; Låg-temperatur fjärrvärme; 4GDH; Flexibilitet; Termisk energilagring TES ; Optimering; Modellering;

    Sammanfattning : District heating (DH) systems have been commonplace in Europe for over a century. These systems have undergone an evolution since their conceiving, and today we are at the precipice of the next major transition from the third-generation district heating system (3GDH) to the fourth generation (4GDH).

  5. 4. Seasonal Thermal Energy Storage for Solar Energy - Lessons learned

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Axel Götling; Dag Björkqvist; [2022]
    Nyckelord :;

    Sammanfattning : För att minska den globala uppvärmningen krävs det tekniska lösningar som minimerar energianvändning. Lagring av värme mellan säsonger är en metod som visar god potential för att lagra värme från sommar till vinter då värmen behövs som mest. LÄS MER

  7. 5. Performance Evaluation of a Photovoltaic/Thermal (PVT) Collector with Numerical Modelling

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mila Ebrahim; [2021]
    Nyckelord :Solar energy; Renewable energy; Photovoltaic thermal collector; PV Thermal; PVT Collector; Performance; Numerical modelling; COMSOL Multiphysics; Ground Source Heat Pump; Solenergi; Förnybar energi; kominerad solcell solfångare; PVT panel; Prestanda; Numerisk modellering; COMSOL Multiphysics; Bergvärme;

    Sammanfattning : In Photovoltaic/Thermal (PVT) technology, both PV and solar thermal technology are integrated in the same module for simultaneous electricity and heat production. Research has shown that there are multiple benefits from integrating PVT collectors with a ground source heat pump (GSHP) system, since it allows for seasonal storage of thermal energy over the year.
