Sweeny Gasification Fact Sheet: Carbon Dioxide Capture and Storage Project

Company/Alliance: ConocoPhillips

Location: Sweeny, Texas, USA

Feedstock: Coal plus petcoke

Size: 680 MW (net)

Capture Technology: IGCC using ConocoPhillips's E-Gas™ gasification process (>90% CO2 removal)

CO2 Fate: Sequestration in neighboring deep saline aquifers and/or EOR

Timing: On hold


In 2009, the Sweeny Gasification Project was selected by the Department of Energy (DOE) to be awarded a $3 million Cooperative Agreement to share cost in the development of the project. Total cost $4.1 billion.


ConocoPhillips did not apply for Phase 2 DOE funding mainly because the timing of the project would have required a large financial commitment. This would have needed to have been made before there was any certainty regarding federal climate change legislation. 

The benefits of the E-Gas™ Technology is that it upgrades the value of domestic petroleum coke, currently being exported. The Wabash River Gasification facility uses ConocoPhillips E-Gas™ technology and has a very low pollutant level. Current well tests are ongoing (June 2010) in Kentucky.
