Abstract

To solve the problem of climate change, carbon neutrality has now become a necessity rather than an option. Hydrogen is not only a energy storage that can supplement the intermittent production of renewable energy, but is also considered a good alternative in the field of utilization as it does not emit carbon dioxide after reaction. In order to revitalize hydrogen vehicles, one of the fields of hydrogen utilization, the construction of hydrogen station infrastructure must be preceded. Prioritization of risk factors is necessary for efficient operation and risk assessment of hydrogen stations, but due to the short operation period of domestic hydrogen stations, there is a lack of frequency data on accidents and their reliability is low. In this study, we aim to identify the causes and consequences of deviations in hydrogen stations through HAZOP analysis. Additionally, we intend to analyze them using Fuzzy-AHP. Through this, we intend to derive the decision values for the causes of deviations in hydrogen stations and apply them to hydrogen accident cases and risk assessments to confirm the reliability and utility of the data.

기후변화 문제를 해결하기 위해 탄소중립은 이제 선택이 아닌 필수가 되었다. 수소는 재생에너지의 간헐적 생산을 보완할 수 있는 저장 매체일 뿐만 아니라 반응 후 이산화탄소 배출이 없어 활용 분야에서도 좋은 대안으로 여겨지고 있다. 수소 활용 분야 중 하나인 수소자동차의 활성화를 위해서는 수소충전소 인프라 구축이 선행되어야 한다. 수소충전소의 효율적인 운영과 위험성평가를 위해서는 위험요인에 대한 우선순위 선정이 필요하지만, 국내 수소충전소 운영 기간이 짧아 사고에 따른 빈도 데이터가 부족하고 그 신뢰도가 낮다. 본 연구에서는 HAZOP을 통하여 수소충전소에서 발생 가능한 이탈의 원인과 결과를 도출하고 Fuzzy-AHP를 활용하여 분석하려고 한다. 이를 통하여 수소충전소에서 발생 가능한 이탈 원인의 의사결정값을 도출하고 수소 사고사례와 위험성평가에 적용하여 데이터의 신뢰성과 효용성을 확인하고자 한다.
