Abstract

In this study, we suggested the direction to lower the risk by analyzing the risk factors for each process for the hydrogen refueling station to be installed in Chungju. HyRAM, one of the quantitative risk assessment tools for hydrogen gas, was used to analyze the hazards. By evaluating the frequency of accidents and consequences for each process, the most dangerous processes and accident factors were presented, and the risk mitigation factors were synthesized. Hydrogen refueling stations are currently in the global infrastructure expansion period, and the lack of accident data could be an alternative to this risk assessment and is expected to be used as a reference for the future expansion of hydrogen refueling stations.

본 논문에서는 충주시 설치 예정인 수소충전소를 대상으로 하여 공정별 위험요소를 분석하여 위험도를 낮출 수 있는 방향을 제시하였다. 위험요소를 분석하기 위해 수소 가스의 정량적 위험성 평가 도구 중 하나인 HyRAM을 이용하였다. 공정별로 사고 빈도와 사고 영향을 평가하여 가장 위험한 공정과 사고 요소를 제시하였으며, 이를 종합한 위험 감쇄 요인을 도출하였다. 수소충전소는 현재 세계적으로 인프라 확충 시기이기 때문에 사고 데이터가 부족해 이러한 위험성 평가가 대안이 될 수 있으며 향후 늘어나게 될 수소충전소 건립에 참고자료로 쓰일 수 있을 것으로 예상된다.
