Toward practical application of the vulnerability evaluation framework for geological sequestration of carbon dioxide

AbstractThe U.S. Environmental Protection Agency has developed a Vulnerability Evaluation Framework (VEF) for the geologic sequestration (GS) of carbon dioxide which can be used as a reference to inform site-specific assessments and risk management decisions. A comparison of the VEF with site assessments of three current GS projects revealed considerable agreement between key elements of the VEF and the three site assessments. It also identified three key topics for further exploration–expansion of scope, treatment of geologic attributes, and management of uncertainty–and an area of future research as projects move forward–a more detailed assessment of receptors
