Port Arthur Fact Sheet: Carbon Dioxide Capture and Storage Project

Company/Alliance: Air Products and Chemicals, Denbury Onshore LLC, University of Texas Bureau of Economic Geology and Valero Energy Corporation

Location: Port Arthur, Texas, US

Start Date: January 2013

Size: 1 Mt/yr

Capture Type: Post-combustion (90% capture) using vacuum swing adsorption technology

CO2 Source: Existing steam-methane reformers

Storage: EOR in West Hasting's and Oyster Bayou oil fields, Texas


Total cost: $431 million. DOE share: $284 million (66%).

The DOE awarded the Port Arthur project $900,000 from the American Recovery and Reinvestment Act (ARRA) in October 2009. The project also received an additional $253 million from the ARRA as part of the DOE's CCS Program's Phase 2 in June 2010. This money is matched by $368 million in private funding.


In June, 2016, Air Products announced that it had successfully captured more than three million metric tons of CO2 at Port Arthur after 3 1/2 years of operation.

The project is made up of 2 Steam Methane Reformers (SMR) located within the Valero Refinery in Port Arthur. The first plant has been capturing CO2 since December 2012, while the second plant completed construction in February 2013 and began carbon capture operations in March 2013.  Both units are now operating at full capacity.  Over 222,000 tons of carbon dioxide have been captured and provided for storage as of early May 2013

The 1 MT/Yr CO2 is captured, dried and purified to 97% purity of CO2 at the Port Arthur facility. The CO2 is then delivered, via a 12-mile connector pipeline, to Denbury's Green Pipeline- Texas. The CO2 will be piped 101-150 km before injection for EOR in Denbury's onshore operations. The CO2 will aid in recovering 1.6-3.1 million additional barrels annually of domestic oil.

The SMR's produce hydrogen to assist in the making of cleaner burning transportation fuels by refinery customers on Air Products Gulf Coast hydrogen pipeline network.


The engineering study and project plan were completed in 2010

The final investment decision was made in 2011

The project started CO2 capture in January 2013

Full scale capture and storage in May 2013
