Sempra Infrastructure is developing the Titan Carbon Sequestration project , a carbon capture and storage (CSS) facility proposal designed to sequester carbon dioxide (CO₂) from the Port Arthur liquefied natural gas (LNG) export facility and potentially others industrial sources.
Titan Carbon Sequestration
As indicated in its statement , the proposed project, located west of Sabine Pass, Texas, and close to the Port Arthur LNG facility, proposes to capture and store CO₂ from the company’s LNG operations.
The project is part of Sempra Infrastructure’s proposed Port Arthur Energy Hub , which could serve as a flagship hub for the energy transition.
The proposed project includes capturing CO₂ from the Port Arthur LNG facility and transporting it by pipeline, where it would be stored via an injection well in a salt formation more than a mile below the Earth’s surface.
In 2024, Titan Carbon Sequestration began the permitting process and filed a Class VI application with the EPA. As part of the ongoing project development, Sempra Infrastructure has also begun geotechnical and territorial studies along the proposed land parcels.
The company indicated that the development of the project depends on completing the required commercial agreements, obtaining and/or maintaining all necessary permits, obtaining financing and reaching a final investment decision, among other factors and considerations.
Safety and environmental management
The Titan Carbon Sequestration project will be designed to meet rigorous industry standards, using proven and well-regulated sequestration protocols in the energy industry.
CO₂ injection wells are regulated by the EPA with standards that provide comprehensive requirements for siting, construction, operation, testing, monitoring, and eventually permanent closure.
When operational, Titan Carbon Sequestration would use real-time monitoring with advanced fiber optic technology and regular site visits to help ensure Sempra Infrastructure’s commitment to safety and sustainability.
