CO2 geological storage risk identification:Methods and application
摘要
Abstract
Carbon dioxide(CO2)capture,utilization,and storage(CCUS)represents a critical technology in the pursuit of global carbon neutrality.As a core component of CCUS technology,CO2 geological storage and utilization offer a viable means of achieving large-scale carbon removal in the near future.The impact on project concept serves as an effective guarantee for the realization of the project concept.Due to the various uncertain factors in the internal and external environment of the project,and with the gradual progress of the project life cycle,new risks will emerge.The frequency of risk recurrence and the various project processes involved will also vary depending on the project.Therefore,risk identification as the first step in the risk evaluation process is an important prerequisite for comprehensive risk evaluation.The goal of risk identification is to identify potential risk sources related to the project.During the identification process,evaluators need to identify various potential risk events and types including geological safety,environmental impact,human health,policy,and social factors,and evaluate the probability and impact of risks.Currently,various analytical methods,including the Delphi method,brainstorming,expert interviews,risk inventory analysis,SWOT technique,risk decomposition structure,and risk graphical analysis technique have been employed both domestically and internationally in the risk identification of CO2 geological storage projects.Each risk identification method has its own advantages and disadvantages.The same project may choose multiple risk identification methods for preliminary investigation of project risks.However,most current research focuses on introducing and applying single methods only.There is a lack of systematic introduction and comparison of multiple different risk identification methods that have not yet been integrated into a complete theoretical framework system for risk identification.Based on a comprehensive review of current risk identification practices,methods,and applications for CO2 geological storage,a comparative analysis of the advantages and disadvantages of various risk identification methods was provided.The risk inventory method was applied to identify risks for the test injection and conceptual project in Ningxia Hui Autonomous Region to guide risk management for the storage project,facilitating its smooth development,and providing an important reference for future large-scale CCUS projects in Ningxia.关键词
