Modelling Hydrogen Refuelling for Light-Duty Passenger Vehicles

Due to the rising concerns over environmental issues and the pressing need to reduce carbon emissions, hydrogen (H2) has gained significant attention as a clean, reliable and sustainable vehicle energy carrier, which is produced from renewable sources.Hydrogen Refuelling Stations (HRSs) are considered a crucial infrastructure for supporting Fuel Cell Electric Vehicles (FCEVs).Nonetheless, a significant obstacle to the commercialization of FCEVs is to store highly flammable hydrogen gas efficiently and securely.Numerous techniques for storing H2 have been devised, however, compressed H2 storage tanks, due to their lightweight and effectiveness, are the most used technique for storing H2 in automobiles.In the present study, a thermodynamic model of HRS was developed to examine the effects of different refuelling parameters such as H2 supply temperature and Average Pressure Ramp Rate (APRR on light-duty FSEVs fueling performance, and State of Charge (SOC) for 70 MPa, 99-liter type IV H2 cylinder.Compared to other refuelling parameters, it was observed that the hydrogen supply temperature has a significant effect on the final tank temperature and SOC.Simulation results show that an increase in H2 supply temperature from -40 to 20 causes an increase of 65.2% in end gas temperature (68.9 to 113.8) and 9.3% lower SOC (92.4% to 84.6%) respectively.
