Abstract

The purpose of this article is to describe a new concept which is social comprehensive risk to discuss safety assessment of technological systems, and conducts a case study on safety assessment of hydrogen energy carrier. The concept mainly consists of three stages: workplace risk, societal risk, and social comprehensive risk. We introduce a framework for societal comprehensive risk assessment, and conduct safety assessment of hydrogen fueling stations. In addition, we outline our findings about qualitative risk assessments of hybrid hydrogen and gasoline fueling stations, detailed consequences analyses of pool fires and hydrogen and leakage, and the commnon causes of incidents and accidents involving hydrogen fueling stations. Two problems are pointed out: One is to lacks a quantitative risk analysis such as individual risk and societal risk, and the other is to scarcely consider a risk treatment such as emergency response and recovery. Finally, a social comprehensive risk analysis is summarized from additional two approaches consisting social value evaluation and life cycle assessment. We offer a new direction to safety assessment of hydrogen fueling stations based on the concept of societal comprehensive risk.
