National Risk Assessment Partnership (NRAP)

Collaborating national laboratories

The safety and effectiveness of large-scale storage of carbon dioxide (CO2) must be based on the predictable long-term integrity of storage sites and demonstrated all-inclusive consideration of potential site-specific risks, including the assessment of residual risk after site closure. NRAP, which comprises five national laboratories executing collaborative research for the U.S. Department of Energy’s Fossil Energy Carbon Sequestration Program, is developing a defensible, science-based quantitative methodology for determining risk profiles at CO2 storage sites. The partnership is also collaborating on key research needed to quantify the residual risk associated with long-term stewardship at a CO2 storage site. Development of a strategic, risk-based monitoring protocol is intended to ensure that monitoring at all stages of a project will effectively minimize uncertainty in the predicted behavior of the site, thereby increasing confidence in storage integrity.
