Titan Carbon Sequestration

The Titan Carbon Sequestration Project, developed by Titan Carbon Sequestration, LLC (a subsidiary of Sempra Infrastructure), is a Class VI carbon storage initiative located in Jefferson County, Texas. The project is designed to sequester CO₂ captured from Sempra’s Port Arthur LNG (PALNG) facility as part of the broader Port Arthur Clean Energy Hub. To support this effort, Sempra has secured 38,000 acres of pore space and surface rights for long-term storage. The site features thick Miocene-aged sand and shale formations with high porosity and permeability, making it geologically well-suited for permanent sequestration. Importantly, no artificial penetrations exist within the defined area of review, minimizing risks to containment. The project includes the planned drilling and operation of two Class VI injection wells, Cronos No. 1 and Rhea No. 1, which will be constructed to meet EPA and Texas Railroad Commission standards.
