Modelling the Refuelling of Hydrogen Fuel-Cell Heavy-Duty Vehicles with Multiple Heterogenous Tanks

Résumé

Road transport greenhouse gases (GHG) emissions accounts for over one fifth of global CO2 emissions in the EU. In Europe in recent years, road transport is the only sector whose emissions have unfortunately not stopped rising. This is particularly true for the heavy-duty mobility, such as trucks, city buses and long-distance buses, which account for over 25% of GHG emissions [1]. One of the most promising technologies to decarbonize heavy-duty transport (trucks, buses, trains, boats) is hydrogen fuel cell technology [2]. The development of this technology requires, besides the development of the vehicles, a parallel effort in the advance of hydrogen refuelling infrastructure and the related refuelling protocols. In terms of vehicle development, the effort required to maintain a range similar to that of fossil-fuelled heavy-duty vehicles is significant. For this purpose, the fuel cell heavy-duty vehicles (FC-HDVs) need bigger onboard storage systems than fuel cell light-duty vehicles (FC-LDVs). To achieve the required hydrogen storage volume, automotive original equipment manufacturers (OEMs) have to exploit any available space in the vehicle by inserting multiple hydrogen storage tanks, often of different sizes, which is not the case for FC-LDVs. This configuration of the on-board hydrogen storage system could have a significant impact on the derivation of parameters for advanced protocols (such as those defined in the European PRHYDE project [3]), as well as on the evaluation of the vehicle's instantaneous state of charge (SOC). Indeed, due to the different tank sizes of the FC-HDV storage system, the mass flow rate distribution between the tanks, the pressure evolution in each tank size and the temperature rise in the different tanks cannot easily be predicted. Thus, the models used to derive the parameters of FC-HDV refuelling protocols should therefore be updated to consider these effects. Moreover, fine modelling of the evolution of these parameters during refuelling would enable us to accurately estimate the thermodynamic state of each tank in the vehicle hydrogen storage system at the end of each refuelling session. Knowing this thermodynamic state will enable the automotive OEMs to know where to place the sensors needed to assess the vehicle's SOC. The aim of this work is therefore to propose a thermodynamic model to simulate the refuelling of a hydrogen storage system for HDVs with multiple heterogeneous tanks.
