6. Evaluation of available electricity storage technologies and the possible economic gain for Växjö Energi
Master-uppsats, KTH/Kraft- och värmeteknologiSammanfattning : As the renewable energy sources are finding more place in the energy generation technologies,the Swedish energy market is also undergoing transformations. Renewable energy sources inthe energy generation system brings more volatility and price fluctuations which can mean challenges and opportunities. LÄS MER
7. Hållbar produktion : En analys av energiförbrukning och avfall för minskad miljöpåverkan inom växellådsmontering
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Scania är en del av Traton Group och är världsledande inom hållbara transporter. Examensarbetet genomfördes hos transmissionsmontering på Scania i Södertälje där även huvudkontoret för forskning och utveckling ligger beläget. I Södertälje finns produktionsenheter för chassi, motor och transmission. LÄS MER
8. Rock cavern as thermal energy storage
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/EnergivetenskapSammanfattning : In the fall of 2019, a comprehensive idea study was conducted on heat storage in two rock caverns located at Näsudden in Skelleftehamn and was part of the project course "Energiteknik, huvudkurs" at Luleå University of Technology. This idea study investigated the conditions of using waste heat from Boliden AB:s copper smeltery (Rönnskär) and storing this waste heat in two rock caverns and use them as seasonal thermal storage tanks, with the purpose of using the heat in the nearby district heating network, thus replacing some of the oil burned at Rönnskär.

9. A Numerical Calculation Tool Design for the Performance Assessment of a Bench-Scale Thermochemical Heat Storage System
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Thermochemical heat storage (TCS) is a technology to convert the heat and cold energy into chemical energy, via reversible chemical reactions, to be stored for heating and cooling applications. TCS technology is gaining interest for its very compact energy storage densities offering attractive thermal energy storage (TES) alternatives to decrease energy-related greenhouse gas(GHG) emissions and contribute to sustainable development.

10. Development of evaluation tools as an approach to pre-design district energy systems : Qualitative modeling and performance simulation using OpenModelica
Master-uppsats, KTH/EnergiteknikSammanfattning : Cities and districts contribute to a large fraction of the total energy consumption in Sweden. The residential- and service sector accounted for almost 40% of the total energy consumption in 2018. The increasing urbanization also puts more importance on the energy supply, distribution and consumption in these areas. LÄS MER
