  1. 1. Flexible Sector Coupling (FSC) of Electrical and Thermal Sectors via Thermal Energy Storage (TES) : A Case Study on Oskarshamn Energi

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

    Author : Raúl Calvo García; Jose María Marín Arcos; [2023]
    Keywords : Flexible sector coupling FSC ; district heating DH ; thermal energy storage TES ; heat pump HP ; capacity optimization; dispatch optimization; open-access tools; Flexibel sektorkoppling; fjärrvärme; termisk energilagring; värmepump; kapacitetsoptimering; leveransoptimering; verktyg med öppen tillgång;

    Abstract : The integration of distributed energy sources and systems is of high relevance for the transition towards a more sustainable energy system. Taking into consideration the  amount of emissions produced by the heating sector, which account for at least half of the energy demand in buildings, district heating systems have the potential to play a key role in the transition, by enabling the integration of various energy sources and provide flexible energy services to the grid.

    Abstract : Cities play a crucial role in sustainable energy system transformation. Urban energy systems account for 75% of global primary energy use, and 70% of global greenhouse gas (GHG) emissions (IEA, 2021). READ MORE

  3. 3. Development and evaluation of solar heating solutions for Villages in the highlands of Peru

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

    Author : Tom Rupert Göransson; [2023]
    Keywords : ;

    Abstract : In the Peruvian highlands, hundreds of thousands of people live in dwellings that are completely unheated. In this climate, nighttime indoor temperatures during the winter could be as low as 0°C. Indoor cold can cause thousands of respiratory diseases and increase winter mortality. READ MORE
