Hackberry Carbon Sequestration

About the Project

Located west of Hackberry, Louisiana, the proposed Hackberry Carbon Sequestration project is expected to capture and store CO2 and potentially reduce the carbon intensity of the liquefied natural gas (LNG) for Cameron LNG customers.

The proposed project includes capturing CO2 from the liquefaction process at Cameron LNG and transporting it by pipeline to an underground injection well where it will be stored approximately 5,000 to 10,000 feet below the earth’s surface. This project is expected to be one of North America’s first world-class carbon sequestration operations.

The proposed Hackberry Carbon Sequestration project will consist of a CO2 compression and processing facility and include pipelines to transport the CO2 to the sequestration well. Sempra Infrastructure intends to co-locate the CO2 pipelines with other existing pipeline infrastructure to minimize the impacts on landowners.

The development of the proposed Hackberry Carbon Sequestration project remains subject to definitive agreements, obtaining the necessary permits and all partners reaching a final investment decision.

Project Benefits

The Hackberry Carbon Sequestration project has the potential to bring positive economic and environmental benefits to Hackberry, Cameron Parish and the surrounding region including:

• Positive economic benefits through the procurement of materials and services
• Generation of an estimated 215 engineering and construction jobs at peak construction and up to 8 full-time jobs to operate and maintain facilities
• Creation of approximately 30 acres of wetland marsh near Cameron LNG

Safety

The proposed Hackberry Carbon Sequestration project will be built to the highest industry standards, using the energy industry’s most proven and well-regulated sequestration protocols. In the state of Louisiana, the Environmental Protection Agency (EPA) has delegated primacy over the regulation of CO2 injection wells to the Louisiana Department of Energy and Natural Resources (LDENR). Under this delegated primacy, LDENR’s standards for siting, construction, operation, testing, monitoring and eventually permanent closure exceed those originally set by the EPA.

During operation the Hackberry Carbon Sequestration project will be monitored live allowing for instant reaction to any changes below the surface. The monitoring plan will use over ten different cutting-edge methods and exceeds EPA and LDENR requirements. The groundwater layer will be monitored with its own specific monitoring well and all wells that pass through groundwater will be triple cased and use corrosion resistant piping. Monitoring will remain in place for the lifetime of the storage project.

Environmental Stewardship

Hackberry The development of Hackberry Carbon Sequestration could help to lower the greenhouse gas (GHG) emissions at Cameron LNG and other industrial facilities while working to provide solutions to help lower carbon emissions for customers in North America and global energy markets.
