Integrated Risk Assessment for CCS

Bi-directional risk assessment in carbon capture and storage with Bayesian Networks

“…A well planned expert elicitation procedure is key to this. Finally, to best cater to the wide range of needs of stakeholders, the use of more than one risk assessment tool may often be helpful (Gerstenberger et al, 2012); a BN can be a useful and detailed tool within a suite of tools to help quantify and communicate the risk.…”

An integrated risk assessment and management framework for carbon capture and storage: a Canadian perspective

“…Given these additional complexities in the risk assessment of CCS projects, the authors recommend the utilisation of a "transparent process that demonstrates [to] the general public how risks and uncertainties are managed" (Koornneef et al, 2012, p.82). Gerstenberger et al (2013) presented an overview of methods and tools that are available for 'integrated risk assessment for CCS'. Both qualitative tools -including brainstorming, a risk register, structured expert elicitation and bow-tie diagrams -as well as probabilistic or quantitative tools are reviewed, with an indication how different tools may be phased-in during stages of a complex decision process.…”

“…The authors strongly recommend in particular the use of an expert elicitation process in order to respond to the inevitable uncertainties and limited data available at the time decisions are made. Gerstenberger et al (2013Gerstenberger et al ( , p.2782) conclude on a note that is fundamental to the overall process: "A key component of an effective risk assessment is communication. The assessment should effectively communicate to varied stakeholders the current state of knowledge with respect to risk within the system.…”

Risk management in carbon capture and geological storage: insights from a structured expert elicitation

“…Since the early 1990s, structured expert elicitation has been used to discern risk ranking, uncertainty and risk management options for wide ranging issues of societal importance (Cooke and Goossens, 2008;Oraby et al, 2016;Tyshenko et al, 2012Tyshenko et al, , 2011. With respect to CCS, this approach has been recommended within a suite of tools to be used in risk assessment (Gerstenberger et al, 2013). It was also applied in a research project, in combination with Bayesian Belief Networks analysis, in considering the detection and stabilisation of a potential CO 2 plume in the CO 2 CRC Otway Stage 2C experiment (Australia) (Gerstenberger and Christophersen, 2016).…”
