Hydrogen fuel cell vehicle provides the significant advantage of high energy conversion efficiency and zero emission. Efficient hydrogen storage methods are vital for successful implementation of the hydrogen‐related technologies. Compressed hydrogen storage has been considered as a promising option in recently commercialized hydrogen fuel cell vehicles. The short filling time and high state of charge of compressed hydrogen storage tank are an essential requirement for fuel cell vehicles. This study presents the detail investigation of refueling compressed storage tank using computational fluid dynamics simulation and heat capacity model. The goal of the simulation is to identify the end temperature and state of charge. Initially, the mathematical model of end temperature and state charge is formulated. Later, the overall heat transfer involved in the refueling process is investigated by heat capacity model based on MC method defined by SAE J2601. The density obtains from the simulation is compared with the National Institute of Standards and Technology database. The SE in simulated results for the state of charge is reduced to <1% after applying the heat capacity method. The results may shade light on better understanding the refueling process of compressed hydrogen storage for fuel cell vehicle.

“…The initial configuration for this study was selected because it was already investigated from the experimental point of view [6] and subsequently from the numerical point of view [9]. The experiments were carried out in the JRC experimental facility GasTeF [6].…”

“…The final pressure is 77.5 MPa and the filling time is 204 s. Those initial and final conditions, and the gas inlet pressure history were selected from one of the experiments that was used for validation purposes [6,9]. The final pressure is higher than 70 MPa since the final temperature at the end of the filling is higher than the ambient temperature because of the compression.…”

“…For this type of tank, it has been shown both experimentally and numerically that the temperature can be considered as uniform in the tank apart from some small regions [6,9]. The incoming jet is colder than the gas inside the vessel and therefore it generates a temperature gradient in a relatively thin region along the tank centreline until a distance where the incoming gas is well mixed with the gas inside the tank.…”

Compressed hydrogen storage CFD Hydrogen safety State of charge a b s t r a c t A major requirement for the filling of hydrogen tanks is the maximum gas temperature within the vessels during the process. Different filling strategies in terms of pressure and temperature of the gas injected into the cylinder and their effects on key parameters like maximum temperature, state of charge, and energy cooling demand are investigated. It is shown that pre-cooling of the gas is required but is not necessary for the whole duration of the filling. Relevant energy savings can be achieved with pre-cooling over a fraction of the time. The most convenient filling strategy from the cooling energy point of view is identified: with an almost linear pressure rise and pre-cooling in the second half of the process, a 60% reduction of the cooling energy demand is achieved compared to the case of pre-cooling for the whole filling.
