Crescent Midstream announced Sept. 20 that the company will develop one of the largest carbon capture and sequestration projects in the U.S. at a gas-fired power plant in Louisiana.

Working with Samsung E&A and using Honeywell carbon capture technology, Crescent will lead an estimated $1 billion project to capture CO2 emitted by Entergy’s Lake Charles Power Station in Westlake, Louisiana.

Construction will consist of the use of CCS technology and a pipeline to carry greenhouse gas emissions away for disposal. Once complete, the facility is designed to capture and permanently store annual CO2 emissions equal to the amount emitted yearly by 600,000 cars, about 3 million tonnes per year (mtpy).

The announcement did not include an estimated completion date.

“We are proud to apply our extensive midstream expertise to create the vital connection between carbon dioxide emission sources and permanent underground storage,” said Jerry Ashcroft, Crescent CEO, in a press release. “Large-scale carbon capture and sequestration has enormous potential to reduce greenhouse gas emissions, and we look forward to helping demonstrate that in one of the highest emitting regions in the United States.”

Thanks to its petrochemical industry, Louisiana emits about 72 mtpy of CO2, second only to Texas in the U.S.  

At the end of 2023, the U.S. Environmental Protection Agency granted Louisiana primacy on carbon capture and storage. The designation made Louisiana the third state that can assume permitting authority for CCS projects.
