1. 6. Life Cycle Assessment of Borehole Thermal Energy Storage

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Saga Karlsson; [2022]
   Keywords : ;

   Abstract : Borehole thermal energy storage (BTES) is a technology used to store energy between seasons. It could therefore be a solution to the seasonal mismatch between the use and production of (renewable) energy, which can be used to increase energy efficiency and reduce greenhouse gas emissions.

3. 7. 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.

4. 8. 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

5. 9. Seasonal Thermal Energy Storage for Solar Energy - Lessons learned

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

   Author : Axel Götling; Dag Björkqvist; [2022]
   Keywords : ;

   Abstract : För att minska den globala uppvärmningen krävs det tekniska lösningar som minimerar energianvändning. Lagring av värme mellan säsonger är en metod som visar god potential för att lagra värme från sommar till vinter då värmen behövs som mest. READ MORE
