  1. 1. Life Cycle Assessment of Absolicon solar thermal collector field for district heating in Härnösand

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ohm Ariyakhajorn; [2023]
    Keywords : Life Cycle Assessment; Solar Thermal Energy; District Heating System; Livscykelanalys; Solvärme; Fjärrvärmesystem;

    Abstract : Global energy consumption has been increasing continuously every year. Many energy sources are utilized. Conventional fossil fuels are not sustainable, and their environmental impacts are more apparent than ever before. For heating purposes, most of the heat still comes from combustion of both non-renewable and renewable energy sources. READ MORE

  3. 2. 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.

  4. 3. A case study on the integration of excess heat from Data Centres in the Stockholm district heating system

    University essay from KTH/Kraft- och värmeteknologi

    Author : Arianna Tofani; [2022]
    Keywords : heat recovery; district heating; circular economy; data centres; excess heat; värmeåtervinning; fjärrvärme; cirkulär ekonomi; datacenter; överskottsvärme;

    Abstract : The data centre industry is becoming more and more important due to the rapid increase of digitalisation in our society. However, data centres are large electricity consumers since electricity is needed for both the Information Technology (IT) equipment and the cooling systems, as a certain temperature must be maintained in the server rooms in order to guarantee service operations.

    Keywords : District heating DH ; low-temperature district heating LTDH ; 4GDH; Flexibility; Thermal energy storage TES ; Optimization; Modelling; Fjärrvärme; Låg-temperatur fjärrvärme; 4GDH; Flexibilitet; Termisk energilagring TES ; Optimering; Modellering;

    Abstract : District heating (DH) systems have been commonplace in Europe for over a century. These systems have undergone an evolution since their conceiving, and today we are at the precipice of the next major transition from the third-generation district heating system (3GDH) to the fourth generation (4GDH).
