  1. 16. 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

    Sammanfattning : There has recently been an increased interest in hydrogen, both as a solution for seasonal energy storage but also for implementations in various industries and as fuel for vehicles. The transition to a society less dependent on fossil fuels highlights the need for new solutions where hydrogen is predicted to play a key role. LÄS MER

  4. 18. Techno-economic analysis of power‑to‑heat‑to‑power storage for a residential building

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Alicia López de Ceballos Regife; [2021]
    Nyckelord :Solar energy; storage; PV installation; Li‑ion; residential sector; latent heat; high temperature; hot water tank; hybrid PV; heat pump; self-consumption; CHP; optimization; Nedler and Mead.;

    Sammanfattning : Despite the share of renewable energies worldwide is increasing, which can help in reducing the CO2 emissions, their unpredictability has become a problem due to the mismatch between generation and demand. Among the different alternatives to solve this problem, energy storage is a very interesting solution. LÄS MER

  5. 19. 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.

  7. 20. Performance Evaluation of a High Temperature Borehole Thermal Energy Storage Under Influence of Groundwater Flow

    Master-uppsats, KTH/Energiteknik

    Författare :Max Hesselbrandt; [2021]
    Nyckelord :;

    Sammanfattning : Recent years have seen a growing interest in large-scale high-temperature borehole thermal energy storage (HT-BTES) as a means to store industrial waste heat and solar energy between the seasons. A profound understanding and characterization of the thermal and hydraulic processes involved in such systems is required for the optimal design as well as for environmental assessments of the storage.
