The National Risk Assessment Partnership (NRAP), Toolset is a software package designed to assess environmental risk performance of geologic carbon dioxide (CO2) storage sites. These tools support industry and regulatory stakeholders as they design and implement safe and effective geologic carbon storage (GCS) projects to sequester large volumes of human-made CO2. The NRAP Toolset provides a defensible, science-based means to quantify long-term environmental risks, amidst large uncertainties in system characteristics and behavior. It features a unique and first-of-its-kind suite of ten tools spanning important components of engineered geologic systems related to potential fluid leakage in the subsurface and potential for (typically minor) earthquakes induced by large volume CO2 injection. Taken together, these ten tools represent the most complete suite of models ever assembled to assess the geological integrity and environmental risk performance of CO2 storage sites related to potential fluid leakage and ground motion. The NRAP Toolset expedites selection and characterization of candidate storage sites, builds confidence of public and industry stakeholders in predictions of storage site performance, aids preparation and evaluation of permits, and informs decisions related to large-scale implementation of geologic carbon storage.
