5. 4. 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.
