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.

“…Several researches were conducted as shown in Table 9. Melideo et al [56] developed different filling strategies to study its effects on 3 key-parameters: the maximum temperature, the SOC and the theoretical cooling energy demand. For energy saving, higher SOC and lower final temperature rise, precooling the gas in the second half of the filling seems more suitable.…”

“…From the perspective of computing resources, if the filling stage only is to be studied a twodimensional model can be built firstly, because a three-dimensional model needs to run completely for several weeks. Melideo et al [56] firstly validate the possibility to use 2D axisymmetric meshes successfully for the CFD simulations of fast filling with pre-cooling. The article shows that the temperature histories for the 3D and 2D meshes are almost completely overlapping.…”

A comprehensive review of the hydrogen storage systems and investigations performed in search for development of fast refueling technology for fuel cell vehicles are presented. Nowadays, hydrogen is considered as a good and promising energy carrier and can be stored in gaseous, liquid or solid state. Among the three ways, high pressure (such as 35 MPa or 70 MPa) appears to be the most suitable method for transportation due to its technical simplicity, high reliability, high energy efficiency and affordability. However, the refueling of high pressure hydrogen can cause a rapid increase of inner temperature of the storage cylinder, which may result not only in a decrease of the state of charge (SOC) but also in damages to the tank walls and finally to safety problems. In this paper, the theoretical analysis, experiments and simulations on the factors related to the fast refueling, such as initial pressure, initial temperature, filling rate and ambient temperature, are reviewed and analyzed. Understanding the potential relationships between these parameters and the temperature rise may shed a light in developing novel controlling strategies and innovative routes for hydrogen tank fast filling.
