  1. 1. 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. 2. In-plane Wetting in Packaging Material and its Consequences for Cap Performance

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Ellinor Carolina Salomonsson; [2023]
    Nyckelord :Tetra Pak®; Aseptic; Paperboard; Pre-laminated hole; Edge wicking; In-plane wetting; Hydrogen peroxide; Cap detachment; Polymer technology; Technology and Engineering;

    Sammanfattning : Aseptic packaging solutions enable long time storage without refrigeration and are an important part of securing food supply globally. The package material consists of multiple layers: A paperboard for robustness, polymers for adhesion as well as shielding the board from liquid, and a barrier protecting the product. LÄS MER

  4. 3. Green hydrogen production in SE4, a business case for large-scale green hydrogen in SE4

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Petter Håkansson; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : As the greenhouse gas emissions keep on increasing the need for solutions to help reduce emissions across all sectors has never been greater. The European Union has pointed out green hydrogen as a step in increasing the sustainability of the energy sector in Europe. LÄS MER

  5. 4. Pre-study and Conceptual Design of a Hydrogen Fuel Cell Driven Wheel Loader

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Jana Caspari; Pijus Bernatavicius; [2022]
    Nyckelord :PEM fuel cell; hydrogen; drive cycle analysis; large-size wheel loader; architecture generation; packaging;

    Sammanfattning : Volvo Construction Equipment is one of the leading construction machinery manufacturers in the world. To stay amongst the leaders, research and development projects for new technologies are crucial. The most important path of development today is the reduction of emissions produced by these heavy duty vehicles. LÄS MER

  7. 5. In vitro study of Biodegradation in Mg-alloys by Isothermal Calorimetry

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Prasad Rajendra Kekare; Akshat Kulkarni; [2021]
    Nyckelord :Isothermal Calorimetry; Degradation of Mg Alloys; Supersaturated solid solution SSSS ; Corrosion rate; Aqueous corrosion.; Technology and Engineering;

    Sammanfattning : Magnesium corrosion in an aqueous environment is a multi-layer, complex process. A literature survey shows significant gaps and the modelling work reported indicates a lack of clarity in understanding the corrosion process. LÄS MER
