초록

국내에서는 수소충전소 보급 및 상용화를 추진 중에 있으나 수소충전소에 대한 위험도 판정이 명확하지 않다. 특히 수소충전소에 대한 위험도 산출 방법 및 허용가능 기준이 명확하지 않은 실정이다. 이에 본 연구에서는 설치 중인 수소충전소 3개소를 선정하여 일반적인 위험도 산출 방법을 활용하여 각각의 수소충전소의 사회적 위험도를 계산해보았다. 일반적인 위험도 산출의 방법으로 개인적/사회적 위험도를 통한 사고빈도를 고려한 개인의 사망활률 및 인근주민의 수에 따른 사망 가능성을 통해 수소충전소의 위험도 수준을 산출할 수 있다. 그러나 이러한 위험도의 경우에도 허용가능 여부를 판단할 기준이 불분명한 실정이다. 이에 국외의 위험도 허용가능 기준을 조사하고 국내의 선정된 수소충전소의 위험도를 적용하여 허용가능 수준임을 고찰해 보았다.

In Korea, hydrogen stations are being promoted and commercialized. However, the risk assessment for the hydrogen station is not clear. In particular, it is not clear how to calculate the risk and acceptable criteria for a hydrogen station. Therefore, in this study, three hydrogen stations being installed were selected and general risks were calculated and the social risk of each hydrogen station was calculated. In general, the method of risk assessment is individual/social risk. This is an individual's death rate considering the frequency of accidents, And the likelihood of death according to the number of nearby residents. These can be used to calculate the level of risk for a hydrogen station. However, this method of calculate risks is the criteria for judging whether it is acceptable are unclear. For this reason, this study investigated the allowable standards for foreign risks and considered that they were acceptable by applying the risks of selected domestic hydrogen stations.
