In order to increase the public acceptance of hydrogen in the process of expanding the supply of gaseous hydrogen and liquid hydrogen vehicle charging stations in accordance with the government"s revitalization of the hydrogen economy policy, the safety of hydrogen vehicle charging stations has been strengthened through the introduction of a risk assessment system, unlike the existing liquefied petroleum gas or high-pressure gas charging stations. In this paper, a risk assessment was conducted for the newly introduced hydrogen vehicle charging station, and a comparative analysis was conducted between the results and the required legal safety distance. To this end, the node classification for the qualitative evaluation of hydrogen refueling stations was classified in the same way as the safety distance facility classification of the law, and the fire explosion caused by hydrogen leakage was separately classified among the scenarios according to the risk review results to conduct a quantitative risk assessment. As a result of quantitative risk evaluation, the personal risk level is 1.0×10<SUP>-7</SUP> (1/year) with a radius of 24 m, and the social risk is 1.5×10<SUP>-6</SUP> (1/year), which satisfies the acceptable criteria. As a result of the risk assessment of gaseous hydrogen and liquid hydrogen charging stations, it was confirmed that the legal safety distance of domestic hydrogen charging stations is longer than the results of safety distance and risk assessment in foreign countries, and it is judged that it is possible to scientifically discuss the safety distance of hydrogen vehicle charging stations on the premise that sufficient accident damage can be minimized through safety measures.
