Protocol for Heavy-duty Hydrogen Refueling: A Modelling Benchmark

For the successful deployment of the Heavy Duty (HD) hydrogen vehicles, an associated infrastructure, in particular hydrogen refueling stations (HRS) should be reliable, compliant with regulations and optimized to reduce the related costs. FCH JU project PRHYDE aims to develop a sophisticated protocol dedicated to HD applications. The target of the project is to develop protocol and recommendations for an efficient refueling of 350, 500 and 700 bar HD tanks of types III and IV. This protocol is based on modeling results as well as experimental data. Different partners of the PRHYDE European project are closely working together on this target. However, modeling approaches and corresponding tools must first be compared and validated to ensure the high level of reliability for the modeling results. The current paper presents the benchmark performed in the frame of the project by Air Liquide, Engie, Wenger Engineering and NREL. The different models used were compared and calibrated to the configurations proposed by the PRHYDE project. In addition, several scenarios were investigated to explore different cases with high ambient temperatures.
