  1. 1. Methodology for Stored Heat “Heat In Place” (HIP) assessment of geothermal aquifers – Exemplified by a study of the Arnager Greensand in SW Scania

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Oskar Sundberg; [2023]
    Nyckelord :geothermal energy; geothermal resource assessment; geothermal potential; volume method; volumetric method; recovery factor; direct use; direct heat; Mesozoic aquifers; Earth and Environmental Sciences;

    Sammanfattning : In the sedimentary bedrock of southwest Scania, located in the southernmost part of Sweden, there are several low-enthalpy Mesozoic sandstone aquifers situated at different depths. These aquifers collectively hold the potential for direct-heat geothermal utilization. LÄS MER

  3. 2. 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

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

    Master-uppsats, Lunds universitet/Geologiska institutionen

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

    Sammanfattning : 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. LÄS MER

  5. 4. Flow Paths in the Húsmúli Reinjection Zone, Iceland

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Sigrún Tómasdóttir; [2018]
    Nyckelord :Húsmúli; Hellisheiði Power Plant; geothermal reinjection; tracer tests; numerical modeling; Húsmúli; Hellisheiði kraftverk; geotermisk injektion; spårtest; numerisk modellering;

    Sammanfattning : Reinjection of spent geothermal fluids has become common practise in geothermal power plants. Reinjection can, despite being mostly beneficial, have unwanted effects such as cooling of nearby production wells and injection-induced earthquakes. LÄS MER

  7. 5. OPTIMAL ENERGY DESIGN FOR A SYSTEM OF PUMPED HYDRO-WIND POWER PLANTS

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

    Författare :LAKSHMI NAGA SWETHA YANAMANDRA; [2018]
    Nyckelord :Pumped Hydro; Wind farm; Energy Storage; Renewable Energy.;

    Sammanfattning : SAMMANFATTNING Medvetenhet och oro kring miljöeffekter från utsläpp av växthusgaser och de minskande resurserna av icke förnybara energikällor har ökat de senaste årtiondena. Utvecklingen av ny teknologi för förnybar energi har drivits fram globalt som ett svar på denna oro. LÄS MER
