    M1-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap; Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Linda Fredriksson; Julia Johansson; [2018]
    Nyckelord :Seasonal thermal energy storage; pit thermal energy storage; borhole thermal energy storage; excess heat; peak load;

    Sammanfattning : Sweden is only utilizing half of the available excess heat. To utilize more of the excess heat a seasonal thermal energy storage could be implemented to store excessed heat from the summer when the demand is lower to the winter when the demand is higher. LÄS MER

  2. 2. Termisk lagring vid Akademiska sjukhuset : Kapning av effekttoppar, ökad redundans och energisäkerhet

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysik

    Författare :Pontus Ohlsson; [2018]
    Nyckelord :;

    Sammanfattning : The Academic Hospital in Uppsala is a major heat energy consumer with an average consumption of 39 GWh/year in recent years, and the heat is supplied by the district heating system which is owned by Vattenfall. The purpose of this work was to investigate if a thermal storage can reduce the costs of district heating consumption and increase the redundancy at the hospital by cutting the heat demand peaks and provide back-up heat in case of district heating deliverance failures.

  3. 3. Termisk energilagring i fjärrvärmenät

    Master-uppsats, KTH/Energiteknik

    Författare :Julia Kuylenstierna; [2018]
    Nyckelord :;

    Sammanfattning : District heating is the most common form of heating in Sweden and as other industries it faces challenges in terms of increased resource utilization and transition to 100% renewable energy sources. Thermal energy storage in district heating networks can bring several advantages, for example enabling the use of excess energy, reduction of equipment size and capacity, as well as load leveling.

  4. 4. Thermal Energy Storage in Sweden and Denmark: Potentials for Technology Transfer

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Michael Harris; [2011]
    Nyckelord :Thermal Energy Storage Sweden Denmark Renewable Integration; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : Management of intermittent renewable energy sources (RES) such as wind and solar is a significant issue for countries with interconnected electricity markets. Increasing amounts of electricity from intermittent RES increases the variability of electricity supply, causing electricity prices to become highly sensitive weather conditions. LÄS MER
