The Longleaf Carbon Capture and Storage (CCS) Hub seeks to significantly reduce the carbon emissions of South Alabama through the development of a stacked storage hub in near proximity to Bucks, Alabama. To do so, the Project will complete relevant permitting, site characterization, and NEPA environmental impact efforts across a project period of 36 months. Over this time, parallel efforts will include the development of a robust Community Benefits Plan, a Pipeline FEED Study, and a CO₂ Source Feasibility Study.

Economically, it is anticipated that the Longleaf Storage Hub will benefit the region over time. CCS projects such as this are expected to prolong the operating life of emitting facilities in the region, many of which are key employers and taxpayers. To date, the Project Team has secured commitments from four separate emitters in the region representing a variety of industries (e.g., electric generation and steel manufacturing). In aggregate, these commitments sum to 2.6 million metric tons of annual CO₂ emissions, or 78 million metric tons of CO₂ over 30 years. Preliminary estimates suggest the three target storage reservoirs have a storage capacity of between 188 and 781 million metric tons of CO₂ at the P10 and P90 confidence level, respectively. The Project builds on the successful DOE/NETL/SECARB Regional Carbon Sequestration Partnership’s (RCSP) CO₂ injection demonstration at the Anthropogenic Test Site, conducted at nearby Citronelle, Alabama. The project’s land position will include approximately 22,000 acres in a sparsely populated rural and forested region of the county.

The Project Team will establish a Community Engagement Team, consisting of subject matter experts within the Project Team and industry volunteers, who will be tasked with ensuring that local communities are involved in project decisions. Further, the Community Engagement Team will establish a network of participating minority serving institutions while developing a robust educational and employment program aimed at increasing access to good-paying energy careers through presentations and job fairs.

Longleaf is led by the Southern States Energy Board. The Project Team includes subject matter experts from Advanced Resources International, Crescent Resource Innovation, ENTECH Strategies, the Geological Survey of Alabama, Tenaska Sequestration Services, the University of South Alabama, and Williams. Baker Hughes Oil Field Services and Environmental Resource Management will participate as vendors while Southern Company Services will participate as the Project Industry Network lead. The Longleaf Storage Hub is being developed by Tenaska, a private, independent energy company headquartered in Omaha, Nebraska, and its partners.
