摘要
二氧化碳捕集、利用与封存(CCUS)作为应对气候变化、减少温室气体排放的一种技术,其环境风险管理是项目开展的重要保障。为规范和指导CCUS项目的环境风险评估工作,环境保护部制定了《二氧化碳捕集、利用与封存环境风险评估技术指南(试行)》(以下简称《指南》)。《指南》定义了地质利用与封存环节的评估范围,但缺乏相关的应用方法。在总结归纳国内外CCUS项目和相关法律法规关于环境风险评估范围的基础上,对决定风险评估空间范围的主要影响因素进行分析,明确了二氧化碳地质封存项目环境风险评估空间范围的确定原则与方法,即简单函数法、数值模拟法和案例对比法。
Carbon dioxide(CO_2) capture,utilization and geological storage(CCUS) is a new climate mitigation technology.The environmental assessment management is an important guarantee for the application of this technology. In order to standardize and guide the environmental risk assessment(ERA) of the CCUS project,the Ministry of Environmental Protection of China released a trial version of "CCUS Environmental Risk Assessment Technical Guidelines"in 2016. The guidelines defined the spatial range of environmental risk assessment of CO_2 geological storage,but lacked the relevant operation method.In this paper,the ERA of worldwide CO_2 geological storage projects and relevant laws and regulations were firstly summarized.Then,the main influence factors of the assessment spatial range were analyzed. Finally,the principle and methodology of determining the spatial range of ERA for CO_2 geological storage were put forward,and three methods,i. e. simple function,numerical simulation,and case contrast,were introduced for the guidelines.
