  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

  3. 2. Integration of geology with geophysics : Case studies from Svalbard

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Sofia Rylander; Anna Sterley; [2022]
    Keywords : Gravity Measurements; Magnetic Measurements; Anomalies; Seismic; Fault Zones; Svalbard;

    Abstract : This is a study where new and old geophysical data together with information found in literature has been integrated to get a better understanding of the geological evolution of Svalbard. The purpose of the study is to acquire and integrate different geophysical data over the Central Spitsbergen Basin (CSB) and across the Billefjorden Fault Zone (BFZ). READ MORE

  4. 3. 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

  5. 4. 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

  6. 5. Self-sufficiency of the vineyard of Ch�teau 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 Ch�teau de la Chaize, situated near Lyon in France. The domain of the Ch�teau 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
