  1. 1. Construction and Validation of a Lab-scaleBorehole Thermal Energy Storage Model

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Haoyang Dong; [2022]
    Keywords : borehole heat exchanger; lab-scale model; experimental construction; experiment test; validation; borrhålsvärmeväxlare; labbmodell; experimentell konstruktion; experimenttest; validering;

    Abstract : Borehole heat exchangers are widely used in heat pumps of residential buildings and industrialsystems. It is known as one of the most energy ecient technologies which provides heatingand cooling by using sustainable geothermal energy. The life time of borehole heat exchangerslasts more than 50 years which is longer than combustion boilers. READ MORE

  2. 2. High Resolution Mapping and Spatial Analysis of Carbon Free Heat Sources for District Heating : A Case Study of Helsinki

    University essay from KTH/Energiteknik

    Author : Filip Norrman; Mattias Persson; [2021]
    Keywords : High-­Resolution Mapping; Carbon-­Free Heat Sources; 4th Generation District Heating; GIS; Hög­upplöst kartläggning; Koldoixidfria värmekällor; 4e generationen Fjärrvärme; GIS;

    Abstract : Heat production together with electricity production stands for 31% of the global CO2 emissions. The production is as of today still highly dependent on fossil fuels, with a global district energy mix share of fossil fuels of 90%. READ MORE

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

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Energiteknik

    Author : Noriko Jia Yong Claudine Ly; [2019]
    Keywords : ;

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

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

    University essay from KTH/Tillämpad termodynamik och kylteknik

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

    Abstract : 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. READ MORE
