  1. 1. Optimering av en framtida solcellsanläggning : En teknoekonomisk analys för Korskyrkan i Uppsala

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

    Författare :Monica Saavedra Granholm; Louise Åkerberg; [2023]
    Nyckelord :;

    Sammanfattning : I detta kandidatexamensarbete planerades en solcellsanläggning av optimal storlek för Korskyrkan i Uppsala efter deras geografiska placering och elkonsumtion. Målet var att ge en oberoende lönsamhetsbedömning genom att jämföra en egen modellering i System Advisor Model (SAM) med offerter från två olika solcellsföretag. LÄS MER

  3. 2. Ion and ENA precipitation onto the upper atmosphere of Venus : Estimate of precipitation maps using data from a hybrid model

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Lorenzo Obersnel; [2023]
    Nyckelord :Eneregetic Neutral Atoms; Venus; Ion precipitation; ENA precipitation; Atomi Neutri Energetici; Venere; precipitazione di ioni; precipitazione di atomi neutri; Energisk Neutral Atom; Venus; Utfällningen joner; Utfällningen Energisk Neutral Atom;

    Sammanfattning : Venus does not have a strong intrinsic magnetic field as the Earth, and its magnetosphere is induced by the interaction of the solar wind with the ionosphere. The near-Venus space environment is characterized by the presence of a bow shock and of an induced magnetic boundary linked to the interplanetary magnetic field orientation. LÄS MER

  4. 3. Energy demand and biogas production in rural areas : A case study in the Raqayapampa community in Bolivia

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

    Författare :Halvor Solheim Haugen; Noel Arancibia Holm; [2023]
    Nyckelord :;

    Sammanfattning : Improved access to energy can greatly improve living standards, and there are correlations between increased access to electricity and higher scores on both the Human Development Index (HDI) and the Educational Development Index (EDI). Increasing access to energy can also help decrease dependability on hazardous fuels and energy sources, such as firewood for cooking. LÄS MER

  5. 4. Evaluating electrolyser setups for hydrogen production from offshore wind power : A case study in the Baltic Sea

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

    Författare :Kenzo Franzén; [2023]
    Nyckelord :electrolysis; energy systems modelling; green hydrogen; offshore wind power; power-to-x; electrólisis; energía eólica marina; hidrógeno verde; modelado de sistemas de energía; power-to-x;

    Sammanfattning : As part of the transition towards a fully sustainable energy system, green hydrogen shows great potential to decarbonise several hard-to-abate sectors. To provide the fossil-free electricity required for electrolysis, offshore wind power has emerged as a suggested option. LÄS MER

  7. 5. Comparative Analysis of Modern Energy Systems for Ice Rinks

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

    Författare :Pendar Hemati; [2023]
    Nyckelord :Ice rinks; refrigeration; heat recovery; CO2; ammonia; propane; Pistas de hielo; refrigeración; recuperación de calor; CO2; amoníaco; propano;

    Sammanfattning : Ice rinks are highly energy-intensive commercial buildings with an average annual energy consumption of 1,000 MWh, most of it being used to cover the simultaneous heating and cooling demands. The aim of this thesis is to find the most energy efficient energy system for ice rinks by evaluating different system modifications and refrigerants. LÄS MER
