Abstract:

Gas is an efficient, stable, and low-carbon clean energy. In the context of achieving carbon peak and carbon neutrality goals, vigorously promoting the development of urban gas can effectively improve energy utilization efficiency. It is not only an effective path to meet the high-quality energy demand of cities, but also an important measure to promote energy conservation and carbon reduction, and achieve green and low-carbon transformation in cities. Due to the characteristics of flammable, explosive, and easily diffusible nature of gas, with the rapid development of urban gas, gas safety issues have become increasingly prominent, and related accidents have occurred from time to time. In order to effectively prevent and resolve gas safety risks and hidden dangers, resolutely curb the occurrence of major accidents, and better promote the high-quality development of the gas industry, this article adhered to the five guiding principles of goal, systematicity, feasibility, scientificity, and localization. For the first time, the methodology of resilience assessment was combined with gas safety assessment. The Analytic Hierarchy Process was applied to establish a quantitative evaluation system for urban gas safety resilience, which sorted out, formulated, and evaluated indicators related to urban gas safety, providing strong support for promoting the intrinsic safety of urban gas.
