  1. 1. 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.

  2. 2. 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).

  3. 3. 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.

  4. 4. Potential for Seasonal Electricity Storage in Borehole Thermal Energy Stores with Heat Pumps

    Master-uppsats, KTH/Energiteknik

    Författare :Elisa Razzetti; [2018]
    Nyckelord :;

    Sammanfattning : In Sweden, there is a substantial increase in renewable power generation that affects the elec-tricity market. At the residential, PV diffusion spreads in the last years due to price drop, while use of heat pump is consolidated. LÄS MER

  5. 5. Waste heat storage and utilization for the case of National Veterinary Institute (SVA), Uppsala, Sweden

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Författare :Stanislav Proshyn; Iryna Bulich; [2017]
    Nyckelord :waste heat; direct distribution; thermal energy storage; hot water storage tank; borehole seasonal storage; heat pump; IDA ICE plant modelling; savings-to-investment ratio; life-cycle costs; Technology and Engineering;

    Sammanfattning : The incineration furnace at National Veterinary Institute (SVA) in Uppsala, Sweden, runs approximately 2,150 hours a year and generates a large amount of waste heat. Some of this heat is partially recovered, and is used for heating one of the main buildings during the furnace operation. LÄS MER
