Abstract

Due to climate change, energy sources that do not emit pollutants such as hydrogen, solar power, and wind power are attracting attention worldwide. In Korea, interest in hydrogen, an eco-friendly energy source, is increasing through the 'Roadmap to Revitalize the Hydrogen Economy' in 2019. In line with this, the supply of hydrogen is actively being promoted, so research related to the safe operation and risk management of hydrogen charging stations is needed. In this study, risk assessment was conducted using HyRAM+ and PHAST v8.7, which are risk assessment programs, based on the report value of the US National Laboratory Sandia National Laboratory (SNL). As a result, the Jet fire scenario conducted using HyRAM+ derived the greatest impact range of 40m in the tube trailer. As a result of Catastrophic rupture using PHAST v8.7, the greatest impact range of 1 psi in the tube trailer was derived with 240m. In addition, as a result of determining the location of the hydrogen charging station using ITALY's Land Use Planning (LUP), it was confirmed that the hydrogen charging station was an appropriate location as F area based on LUP.

기후변화로 인해 수소, 태양열, 풍력 등 오염물질을 방출하지 않는 에너지원들이 전 세계적으로 주목을 받고 있다. 대한민국에서는 2019년 '수소 경제 활성화 로드맵'을 통해 친환경 에너지원인 수소에 관한 관심을 높이고 있다. 이에 맞추어 수소 동력 보급을 적극적으로 추진하고 있어 수소충전소의 안전한 운영 및 위험관리 관련 연구가 필요하다. 본 연구에서는 미국 국립연구소 Sandia National Laboratory(SNL)의 report 값을 기반으로 위험성 평가 프로그램인 HyRAM+과 HyRAM+과 PHAST v8.7을 활용하여 위험성 평가를 시행하였다. 그 결과 HyRAM+을 활용하여 실시한 Jet fire 시나리오는 튜브 트레일러에서 40m의 가장 큰 영향범위를 도출했다. PHAST v8.7을 이용한 Catastrophic rupture 결과 튜브 트레일러에서 1psi의 영향범위는 240m로 가장 큰 영향범위를 도출했다. 추가로 ITALY의 Land Use Planning(LUP)를 사용하여 수소충전소의 위치 적합성을 판단한 결과 LUP 기준 F 지역으로 수소충전소는 적합한 위치인 것을 확인했다.
