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

    University essay from KTH/Energiteknik

    Author : Max Hesselbrandt; [2021]
    Keywords : ;

    Abstract : 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.

  3. 2. Hydronic Pavement Systems for Sustainable Winter Road Maintenance in Sweden : A Study of Hamnbacken in Visby

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Chirin Barikan; [2019]
    Keywords : Winter road maintenance; sustainable infrastructure; geoenergy; renewable energy; Nordic climate; BTES; surface water source heat; Halkbekämpning; hållbar infrastruktur; geoenergi; förnybar energi; nordiskt klimat; borrhål; sjövärme;

    Abstract : In countries with harsh winter climates extensive winter road maintenance is necessary to achieve traffic accessibility and road safety. These measures have high economic and environmental costs as snow free roads and winter road maintenance in Sweden today is achieved by a combination of mechanical snow clearance and the spreading of salt to prevent ice formation.

  4. 3. 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

  5. 4. Construction and test of a new compact TRT equipment

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Linus Olausson; [2018]
    Keywords : ;

    Abstract : A relevant contribution to sustainable development can be achieved by providing efficient solutions for heating buildings. The use of a heat pump taking heat from the bedrock with the help of a borehole heat exchanger is a common solution in Sweden to accomplish this. READ MORE

  6. 5. Analyses of thermal conductivity from mineral composition and analyses by use of Thermal Conductivity Scanner : a study of thermal properties of Scanian rock types

    University essay from Lunds universitet/Geologiska institutionen

    Author : Thomas Andolfsson; [2013]
    Keywords : bedrock; geoenergy; thermalconductivty; Scania; Earth and Environmental Sciences; Technology and Engineering;

    Abstract : With an increase in demand for green energy the interest has grown in Geoenergy. The bedrock may function both as energy source and as energy storage, which makes it suitable for both heating and cooling. The thermal properties of the bedrock are essential when effectively planning and designing a geothermal energy well. READ MORE
