Quantification of Risk Profiles and Impacts of Uncertainties as part of US DOE's National Risk Assessment Partnership (NRAP)

摘要

The National Risk Assessment Partnership (NRAP) is a US-Department of Energy (US-DOE) effort focused on developing a science-based methodology for quantifying risk profiles at geologic CO2 sequestration sites. Risk profiles are calculated using an integrated assessment modelling (IAM) approach which treats a geologic CO2 storage site as a system and uses a system modelling approach to predict time-dependent behaviour of the storage site. We have developed first generation risk profiles associated with a few key potential impacts due to CO2 leakage from a sequestration reservoir, including change in groundwater quality in a shallow aquifer and return of CO2 to the atmosphere.
