Hydrogen is gaining attention as a clean energy alternative to fossil fuels. In Korea, hydrogen refueling stations (HRS) are continuously expanding as hydrogen mobility is commercialized, and it is expected to account for 33% of Korea's total energy consumption by 2050. Hydrogen is easily ignited with low ignition energy, and its wide flammability range and fast combustion rate can lead to fires/explosions after leakage, causing major accidents. In Korea, hydrogen is handled in a semi-enclosed space according to special cases, which is very dangerous due to hydrogen leakage, and explosion safety can be improved by removing the installation of explosion venting and ventilation. For this reason, we would like to study the safety management of packaging HRS, which are semi-enclosed spaces.
