Probit 모델을 이용한 도심지 내 수소충전소 종류에 따른 화재 위험성 평가

초록

Although the hydrogen is being spotlighted as a next-generation energy source, it has problems of installing charging stations due to its inherent hazard and operation at high-pressure as well. In previous studies, several researchers have investigated to assess the risk of hydrogen charging stations from the viewpoint of failure. It was also assumed that the hydrogen station was not located in highly populated urban area. In this study, the extent of damage was calculated and evaluated using the Probit model of the hydrogen station according to the hydrogen production method. The steam information of hydrogen station was obtained through process modeling of each hydrogen charger and then the hazard and accident scenario were defined considering operating conditions. The defined accident scenario was calculated using PHAST 7.21 program, which was used to calculate the damage impact to the distance where there is a possibility of human injury through the probit model. This resulted in the largest damage footprint in the event of a fire in a hydrogen trailer. It has been evaluated that the on-stie hydrogen refueling station is safer than the hydrogen charging station using hydrogen alone hydrogen.
