On September 18, 2023, Denver-based Carbonvert Inc. and Castex Carbon Solutions LLC, a wholly owned subsidiary of Castex Energy, announced that they have executed an operating agreement with Louisiana to develop a 24,000-acre tract of land offshore of Cameron Parish in southwestern Louisiana to permanently store carbon dioxide more than a mile beneath the surface under an impermeable layer of cap rock.[1] The project, known as Cameron Parish CO2 Hub, will have a total storage capacity of more than 250 million metric tons of CO2 and will be operated by Castex. The companies plan to take CO2 from industrial emitters around the Cameron Parish area and “anticipated greenfield projects, notably ammonia and [liquefied natural gas] facilities.” The project has a first CO2 injection target of 2027. Currently, the companies are in discussions with potential customers about the transportation and storage of CO2 from industrial facilities in Lake Charles, Louisiana, and Port Arthur, Texas, as well as regional LNG sites.
