  1. 1. The Role of Technology Shifts in Urban Decarbonization Modelling : Scenario creation and implementation

    Master-uppsats, KTH/Energisystem

    Författare :Batiste Fourniols; [2024]
    Nyckelord :Urban area; Decarbonization policies; Scenario modeling; District heating; Gas distribution network; Geospatial resolution; Stadsområde; utfasning av fossila bränslen; scenariomodellering; fjärrvärme; gasdistributionsnät; geospatial upplösning;

    Sammanfattning : This work includes modelling of decarbonization scenarios at the scale of an urban area, providing policy insights and a methodology focusing on introducing district heating and maintaining the existing gas distribution network in a case study. With a focus on reducing gas consumption in the residential and tertiary sectors, the research integrates scenario developments giving a methodology to develop district heating, requiring a careful balance in selecting the optimal scale for city-wide analysis.

  3. 2. Improvement of anautomatic networkdrawing algorithm in thecontext of utility networks

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Hyacinthe Ménard; [2024]
    Nyckelord :District Heating Network; Mathematical Optimization; Python; Fjärrvärme; Optimeringslära; Python;

    Sammanfattning : The European Union’s ambitious climate targets necessitate substantial reductions in greenhouse gas emissions, particularly within the heating and cooling sector, which accounts for a significant portion of energy consumption. District Heating and Cooling (DHC) systems emerge as a key solution for decarbonizing this sector by enabling high efficiency heat production and the integration of renewable and carbon-neutral energy sources.

  4. 3. Heat atlas of Gotland : A GIS-based support tool for modelling the heat sector.

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Hugo Segerström; [2023]
    Nyckelord :Heat atlas; GIS; heat sector; energy system; energy system modelling; TIMES; QGIS; district heating; spatial data; energy transition; GIS; energisystems modellering; TIMES; värmesektorn; fjärrvärme; värmeatlas; QGIS; geografisk data; energisystem;

    Sammanfattning : With sharp climate goals to be climate neutral by 2045, Sweden needs to rapidly change the present energy system. The Swedish government has assigned Gotland as a pilot area for the energy transition, due to its geographical constrains as an island, and because of the major structural changes planned for Gotland’s energy supply and industrial establishment.

  7. 5. Utformning av modell för simulering av distributionsnät för fjärrvärme

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Arvid Press; [2022]
    Nyckelord :district heating; modelling; fjärrvärme; modellering;

    Sammanfattning : Climate change and the increase of carbon dioxide in the atmosphere is an ongoing problem affecting the earth globally. To break this trend and revert the changes a continuous upgrade of the current energy system is needed, one way of doing this is by using models to simulate new systems. LÄS MER
