Summary:Recently, study on renewable energy has been carried out due to environmental pollution and depletion of fossil fuels. In particular, hydrogen, a clean energy, is environmentally friendly because it produces only pure water as a by-product of the reaction process. In the case of liquified hydrogen, the energy density is about 848 times higher than that of gas hydrogen, but it is not currently widely used due to technical constraints and other problems because it has to maintain a cryogenic state. Therefore, in this work, numerical method was verified by comparing results of precedent study and this study. And relationship between Reynolds number and Nusselt number was confirmed. Based on this results, code was made by using programming language (Fortran 77) with relationship between Reynolds number and Nusselt number to analyze the state of charge (SOC). Variables were set as mass flow rate, temperature of hydrogen gas, and initial tank temperature. As a result, the effect of hydrogen gas temperature is dominant as a factor that affects the temperature of the fully charged state. Therefore, it is determined that the temperature control of the hydrogen storage will be possible through the hydrogen gas temperature setting.
