Supported by the dualcarbon goal and various new energy policies, the hydrogen energy industry has experienced rapid development. As the hub of upstream hydrogen production, midstream hydrogen storage and downstream application markets in the hydrogen energy industry, the construction and development of hydrogen refueling stations are inseparable from safety risk assessment. In this study, a quantitative risk assessment method for hydrogen refueling stations was established, and a quantitative risk assessment software Safeti was used to evaluate the risk of a hydrogen refueling station. Based on the individual risk contours and social risk analysis results, the accident risk level of the hydrogen refueling station was determined. Finally, to ensure the safety of hydrogen refueling stations, risk prevention and control measures are proposed from the aspects of standards, safety systems and institutional frameworks.
