  1. 16. Techno-economic assessment of CO2 refrigeration systems with geothermal integration : a field measurements and modelling analysis

    University essay from KTH/Energisystem

    Author : Fabio Giunta; [2020]
    Keywords : CO2 Refrigeration; Supermarkets; Heat Recovery; Geothermal Storage; Energy Efficiency; Boreholes; Techno-Economic Assessment;

    Abstract : Several CO2 transcritical booster systems in supermarkets use the potential of integrating geothermal storage, enabling subcooling during warm climate conditions as well as being a heat source during cold climate conditions. First of all, field measurements of one of these systems located in Sweden were analysed with particular focus on the heat-recovery performance. READ MORE

  3. 17. Virtual Phenomenology and Viewshed Analysis of the Colossi of Memnon during the reign of Amenhotep III in VR and GIS based environment

    University essay from Uppsala universitet/Institutionen för arkeologi och antik historia

    Author : Niklas Ekholm; [2020]
    Keywords : Colossi of Memnon; Kôm-el Hetan; Amenhotep III; Phenomenology; VR; Virtual reality; Viewshed analysis; Visibility; Borehole analysis; Nile river; Reconstruction; Constructed landscape.; Memnons stoder; Kôm-el Hetan; Amenhotep III; Fenomenologi; VR; Virtuell verklighet; Borrhålsanalys; Rekonstruktion.;

    Abstract : The Colossi of Memnon are a prominent feature of the constructed landscape at ancient Thebes (modern day Luxor, Egypt). They were built on the West Bank during the later years of Amenhotep III reign and they stood in front of his royal cult temple, Mansion of Millions of Years, known today colloquially as Kôm el-Hetan.

  4. 18. Fracture characterization in magmatic rock, a case study of the Sosa-dyke (Neuquén Basin, Argentina)

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Nilsson Jim; [2020]
    Keywords : dyke; magmatic intrusion; fractures; Sosa dyke; permeability; intrusion; magmatisk intrusion; sprickor; Sosa intrusionen; permeabilitet;

    Abstract : There are many examples worldwide were fossil magmatic intrusions influence the local water and energy supply. Due to that intrusions can act as a conductor and a reservoir, but also as a barrier for fluids and gases in the ground. The decisive feature between conductor or barrier in an intrusion is its fracture network. READ MORE

  5. 19. Internal geology and emplacement processes of Kimberlites, Case Study from the Tsabong Kimberlite Field, Botswana

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Mpho Ndebele; [2020]
    Keywords : Kimberlites; Geology; Emplacement Processes; Botswana;

    Abstract : The Crateceous (85 Ma) MK1 pipe is part of the Tsabong kimberlite cluster located approximately550km south west of Gaborone and geologically found within the Kapvaal Craton. The Tsabongkimberlite field consists of 86 known kimberlites. The MK1 pipe is the largest of this cluster at 140ha,1. READ MORE

  6. 20. 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
