  1. 1. 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.

  3. 2. Subsurface characterization of the Lund Sandstone – 3D model of the sandstone reservoir and evaluation of the geoenergy storage potential, SW Skåne, south Sweden-merged

    University essay from Lunds universitet/Geologiska institutionen

    Author : Erik Aldenius; [2019]
    Keywords : Energy storage; CAES; geothermal energy; Lund Sandstone; renewable energy; geoenergy; Earth and Environmental Sciences;

    Abstract : In order to decrease the dependence on fossil fuels it is of paramount importance that renewable sources are used as effectively as possible. Therefore it is necessary to store excess energy when supply is higher than de-mand. One way to do so is by storing the energy as compressed air in a porous aquifer. READ MORE

  4. 3. Evaluation of Current and Feasible Future Use of Geothermal Energy at Chinyunyu Hot Spring, Zambia

    University essay from KTH/Kraft- och värmeteknologi

    Author : Christopher Kapasa; [2014]
    Keywords : ;

    Abstract : The main source of geothermal energy is the heat flow from the mantle beneath the Earth’s surface, generated by the gradual decay of radioactive isotopes in the Earth‘s crust. A hot spring is produced by the emergence of geothermally heated groundwater flowing out to the Earth’s surface. READ MORE

  5. 4. 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
