“…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.…”

“…It has been shown both experimentally and by numerical simulations that the temperature threshold can be exceeded e.g. a 29 L tank type 4 that is refilled in 200 s at 20 C of ambient temperature [6,7]. The technological solution envisaged to tackle that issue is to pre-cool the gas before injecting it into 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.

Investigation of structural stability of type IV compressed hydrogen storage tank during refueling of fuel cell vehicle

The storage of hydrogen in compressed form has evolved as the primary choice for fuel cell vehicle manufacturers. Currently, composite tanks are a mature and promising option for compressed hydrogen storage for the on‐board application. Type IV tank with carbon fiber/epoxy composite with high density polyethylene liner provides high strength, lightweight, and excellent resistance to fatigue and corrosion. However, high pressure and temperature generated during refueling affect the structural stability of the composite tank. The objective of the work is to investigate the mechanical and thermal response of the tank at different refueling conditions specified in SAEJ2601. For this, finite element analysis was used to examine the stresses, strains, deformation, and failure evolution during refueling. The results show good agreement between simulated and experimental reported burst pressure of the tank with 5.52% difference which might be due to the type of carbon fiber used, fiber winding pattern, number of layers, and loading conditions considered for the analysis. The results presented here show some new insight into behavior of composite tanks under dynamic load conditions of refueling.

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.
