Magnolia

Oxy’s Magnolia Sequestration Hub is a planned large-scale carbon dioxide geologic storage hub being developed by 1PointFive (a wholly owned subsidiary of Occidental) in Allen Parish, Louisiana. It is part of the DOE’s CarbonSAFE Phase III initiative and has received federal funding to advance site characterization, permitting, and environmental approvals. The project is designed to securely store at least 60 million metric tons (Mt) of CO₂ over approximately 15 years, with potential to support injection capacities in the 4–10 million metric tons per year range once fully developed. The hub will serve multiple industrial and capture facilities along the Louisiana Gulf Coast, capturing CO₂ from point sources or DAC facilities and permanently storing it in deep saline reservoirs more than a mile underground. Geological characterization—including stratigraphic core sampling and modeling—indicates suitable formations (e.g., Frio and other porous deltaic sandstone zones with regional confining units) for long-term storage, and work is underway to secure Class VI injection permits and plan infrastructure such as multiple injection wells. The project’s size, estimated storage capacity (60 Mt+), annual injection potential, and proximity to emissions sources position Magnolia as a key regional CCS asset to support industrial decarbonization.
