Sempra Infrastructure signed a participation agreement with TotalEnergies, Mitsui & Co. Ltd., and Mitsubishi Corp. for development of the proposed Hackberry Carbon Sequestration (HCS) project in Southwest Louisiana.
The agreement contemplates that the combined Cameron LNG Phase 1 and proposed Phase 2 export projects would potentially serve as the anchor source for the capture and sequestration of carbon dioxide (CO2) by the HCS project, Sempra said in a May 23 release. The CO2 will be captured by the acid gas removal units, dehydrated, compressed, and transported by pipeline about 10 km away to be stored in a saline aquifer using an injection well. The agreement also provides the basis for the parties to enter into a joint venture with Sempra Infrastructure for the HCS project.
In 2021, the Hackberry Carbon Sequestration project filed an application for a Class VI Injection well permit from the US Environmental Protection Agency for permanent storage of up to 2 million tonnes per year of CO2.
Development of the HCS project is subject to risks and uncertainties, including signing additional project-related agreements, securing necessary permits, and reaching a final investment decision.
