  1. 6. Hydrogen storage systems : Methodology and model development for hydrogen storage systems performance evaluation based on a transient thermodynamic approach

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Kreshnik Margaritari; [2023]
    Nyckelord :Hydrogen; Hydrogen storage system; Hydrogen filling process; Hydrogen storage system operation; Hydrogen storage system design; Hydrogen fast filling; Hydrogen tank modelling;

    Sammanfattning : The overall performance of a hydrogen storage system can be affected by various parameters, such as operation and design parameters, but also by the state of the hydrogen contained inside the storage tanks. In this work, a methodology is developed to evaluate the state of the hydrogen during the filling process and its impact on the overall system performance under variable operation conditions and design parameters.

  3. 7. Fastläggning av arsenik med nollvärt järn i mikrostorlek : Uppföljning av ett pilotskaleförsök

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Frida Aronsson; [2023]
    Nyckelord :contaminated soil; arsenic; zero-value iron; mZVI; pilot test; pilot study; förorenad mark; arsenik; nollvärt järn; mZVI; pilotförsök; pilotstudie;

    Sammanfattning : Land contaminated with arsenic is a major problem as arsenic is toxic and poses a major health risk to both humans and animals. There are several remediation methods, both in-situ and ex-situ, to prevent and deal with pollution problems in different ways. LÄS MER

  4. 8. THIRD HAND : A solution for the fuel tank assembly at Scania Södertälje

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :SandraMarie Westerberg; Tova Ödesjö; [2023]
    Nyckelord :Industrial Design Engineering; Ergonomics; Human-centered design; User-centered design; Safety; Third hand; Automotive; Production; Teknisk Design; Ergonomi; Människocentrerad design; Användarcentrerad design; Säkerhet; Tredje handen; Fordons industri; Produktion;

    Sammanfattning : Scania recently introduced a new fuel tank design. This new design arose a need for extra help when mounting the tank in production, which was solved with two little hooks on each tank. These hooks are today known as the current third hand solution. LÄS MER

  5. 9. Status Mapping of tank to grave management of Low-GWP refrigerants.

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

    Författare :Sandra Parra Gimeno; [2023]
    Nyckelord :Refrigerant; Blends; Synthetic low-GWP refrigerant; Natural refrigerant; Global Warming Potential GWP ; Tank-to-grave; Interviews.; Köldmedier; Blandning; Globalt uppvärmningspotential GWP ; Låg-GWP köldmedier; Naturligt köldmedier; installation till destruktion; Intervjuer.;

    Sammanfattning : Refrigeration plays a vital role today in various residential, commercial, and industrial processes, requiring refrigerants to facilitate the cooling or heating processes. Over time, refrigerants have undergone significant changes to meet technological, social, environmental, and economic needs. LÄS MER

  7. 10. Investigation of different ventilation profiles to avoid stratification in Nearly Zero Energy Buildings

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Alazne Irene Varela Santana; [2023]
    Nyckelord :stratification; water model; comfort; mixing; temperature; potential energy; net zero energy building;

    Sammanfattning : This research paper examines possible solutions for the problems that warm air heating is suffering in Nearly Zero Energy Buildings. These NZEBs are passive houses constructed to have high energy efficiency where the quantity of power used is equal to the power created annually, produced locally or in the surroundings by renewable energy sources.
