Abstract
A new simulation tool has been developed to provide insights into the refueling process of hydrogen. The tool is based on existing models, including a 0D gas model and a 1D wall model, which have been refined to assist companies like Future Proof Shipping, which rely on compressed hydrogen tanks. Although the model is still subject to changes and not fully reproducible during the validation process, it has accurately computed the temperature evolution for large tanks ranging from 1500-2100L. Based on this evolution, it is recommended to maintain the inlet temperature of hydrogen at -20°C or lower. Furthermore, it is suggested that Future Proof Shipping should consider using a type 3 hydrogen tank, which features an aluminum liner and better heat conductivity. This results in more efficient heat conduction away from the hydrogen.
