The Mississippi CCS Project

Abstract

The Mississippi CCS Project is a proposed large-scale industrial carbon capture and sequestration (CCS) project which would have demonstrated advanced technologies to capture and sequester carbon dioxide (CO 2 ) emissions from industrial sources into underground formations. Specifically, the Mississippi CCS Project was to accelerate commercialization of large-scale CO 2 storage from industrial sources by leveraging synergy between a proposed petcoke to Substitute Natural Gas (SNG) plant that is selected for a Federal Loan Guarantee and would be the largest integrated anthropogenic CO 2 capture, transport, and monitored sequestration program in the U.S. Gulf Coast Region. The Mississippi CCS Project was to promote the expansion of enhanced oil recovery (EOR) in the Mississippi, Alabama and Louisiana region which would supply greater energy security through increased domestic energy production. The capture, compression, pipeline, injection, and monitoring infrastructure would have continued to sequester CO 2 for many years after the completion of the term of the DOE agreement. The objectives of this project were expected to be fulfilled through two distinct phases. The overall objective of Phase 1 was to develop a fully definitive project basis for a competitive Renewal Application process to proceed into Phase 2 - Design, Construction and Operations. Phase 1 included the studies that establish the engineering design basis for the capture, compression and transportation of CO 2 from the MG SNG Project, and the criteria and specifications for a monitoring, verification and accounting (MVA) plan at the Soso oil field in Mississippi. The overall objective of Phase 2, was to execute design, construction and operations of three capital projects: the CO 2 capture and compression equipment, the Mississippi CO 2 Pipeline to Denbury's Free State Pipeline, and an MVA system at the Soso oil field.
