1. 1. Modelling of Fluid Flow and Contaminant Transport in Fractured Rock : Case Study

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Ebba Pegestam; [2022]
   Keywords : Contaminant transport; Discrete Fracture Network; Geology; Geohydrology; Groundwater transport; Fracture; Drinking water; Contamination; Föroreningar; flödestransport; spricknätverk; geologi; geohydrologi; grundvattentransport; sprickor; dricksvatten;

   Abstract : Drinking water contamination is a big concern in Sweden and is commonly traced back to being waste from former manufacturing industrial sites. Pollutants in the topsoil can be remediated by several techniques, such as decontamination or excavation but the toxins already enclosed in the bedrock cannot be treated the same and is harder to track possible contaminant pathways.

3. 2. 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

4. 3. Data center cooling solutions : A techno-economical case study of a data center in Sweden

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Joel Sjökvist; Fredrik Magnusson; [2022]
   Keywords : Energy systems; Data center cooling; Free cooling; Air cooling; Geothermal cooling; Mechanical cooling; District cooling; Building conversion; Dry cooler; Cooling machine; Borehole; PUE;

   Abstract : Given the coinciding growth-trend in the production of consumer electronics and generation of data, the increase in server halls and data centers, as a means for hosting storage capacity for the generated data, has been prominent over the last decades. The establishment of data centers in already existing infrastructure can entail major changes in terms of energy system design. READ MORE

5. 4. 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

6. 5. 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
