Scale: Large

Status: Operative

Capital cost: approx $384 million

Year of operation Q1, 2013
Industry: Oil and gas processing

Capture method: Pre-combustion

New or retrofit: Retrofit
Transport of CO2 by: Pipeline

Type of storage: EOR

Volume: 1 million tonnes/CO2


Air Products & Chemicals and the US Department of Energy have progressed plans to design, build and operate a capture plant at Air Products' existing Port Arthur refinery in Texas. Construction of a hydrogen plant with carbon capture began in August 2011, and in January 2013 the facility began capturing CO2 and transporting it via the Denbury Green Pipeline to Denbury's West Hastings oilfield for EOR operations.

The demonstration, which is the first of the DoE’s Industrial Carbon Capture and Storage (ICCS) Program integrated projects to begin operating, will now demonstrate the potential of full-chain CCS technology at commercial scale. It will also involve a monitoring, verification, and accounting programme to ensure the injected CO2 remains safely stored underground in the long term.

Eventually, the facility will capture up to 1 million tonnes a year of CO2 from two steam methane reformers, which are used for the large-scale production of hydrogen. Venture partner Denbury Resources has provided pipeline infrastructure to transport the CO2 to the West Hasting's and Oyster Bayou oilfields for use in EOR projects.

Air Products designed the CO2 removal units - using ‘vacuum swing adsorption’ - which have been retrofitted to each reformer train. The project team also includes the University of Texas Bureau of Economic Geology, and Valero Energy Corporation, and is managed by the DoE's National Energy Technology Laboratory (NETL).

Air Products is also involved in a number of global CCS demonstration projects, including work with Vattenfall AB, the Alberta Energy Research Institute, and Imperial College London.


DoE is funding 66% of the approximate $384 million cost of the project. In October 2009, the project was awarded almost $962,000 funding from the American Recovery and Reinvestment Act (ARRA) and an additional $253 million in Phase 2 funding from ARRA in June 2010 under the Industrial Carbon Capture and Sequestration (ICCS) Program. The first phase of research and development included $22.5 million in private funding.


In May, 2013 the US Department of Energy announced that the plant has successfully began to capter carbon dioxide and is using it for enhanced oil recovery and securely storing it underground. Capture, transport and utilisation operations began in January 2013. Plant construction began in August 2011. An engineering study and project plan had been completed in mid-2010. Start-up and commissioning stayed on track for late 2012, and the project hit the expected Q1 2013 start-up date.
