  1. 6. Återladdningsförmågan hos en Bergvärmepump

    Uppsats för yrkesexamina på grundnivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Felix Johansson; [2020]
    Nyckelord :;

    Sammanfattning : Geothermal energy that is being used for space heating with help of heat pumps is getting more and more common. In Sweden 2016, there was over 300 000 different facilities using geothermal energy with the help of bore hole heat exchangers, so called ground source heat pumps (GSHP). LÄS MER

  3. 7. A Numerical Analysis on the Effects of Using CO2 as a Driving Fluid for a Geothermal Plant

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :David Bennich; [2020]
    Nyckelord :reinjection; two-phase flow; geothermal energy; CO2 sequestration; iTOUGH2; ECO2N; återinjektion; tvåfasflöde; geotermisk energi; koldioxidlagring; iTOUGH2; ECO2N;

    Sammanfattning : To limit the effect of global warming society needs clean energy sources and to reduce emissions of greenhouse gases into the atmosphere. By combining carbon capture and storage technologies together with geothermal power production it is possible to gain fossil free energy while potentially storing CO2 at the same time. LÄS MER

  4. 8. Self-sufficiency of the vineyard of Ch�teau de la Chaize : Design and Simulation of a grid-connected PV system in South of France

    Master-uppsats, KTH/Energiteknik

    Författare :Noriko Jia Yong Claudine Ly; [2019]
    Nyckelord :;

    Sammanfattning : The task of this master thesis is to evaluate the potential and economic feasibility of a solar photovoltaic project at the Castle Ch�teau de la Chaize, situated near Lyon in France. The domain of the Ch�teau de la Chaize aims to be more ecologically responsible, by producing organic wine, using geothermal energy and producing its own electricity, using solar energy. LÄS MER

  5. 9. Geothermal function integration in ice rinks with CO2 refrigeration system

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Juris Pomerancevs; [2019]
    Nyckelord :Ice rinks; CO2 refrigeration system; geothermal energy; heat recovery.; Ishallar; CO2 kylsystem; geoenergi; värmeåtervinning;

    Sammanfattning : Ice rinks are energy intense industrial applications. A typical single sheet ice rink in Sweden uses about 1000 MWh/season. A state-of-the art ice rink systems can use less than 500 MWh/season, indicating the potential for improvements. LÄS MER

  7. 10. Deriving Geothermal Reservoir Properties from Tomographic Models

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Samantha Kim; [2019]
    Nyckelord :Geothermal reservoir; super-critical fluids; optimization; seismic tomography; effective medium model; Iceland; Geotermisk energi; seismisk; mediummodel; reservoir; spricktäthet; superkritisk vätska optimisering;

    Sammanfattning : The effectiveness of the heat transfer in a geothermal reservoir strongly depends on its temperature, pressure and rock type. A porous and fractured rock is essential to provide a hot fluid circulation to a geothermal power plant. LÄS MER
