Advancing direct air capture & a regional CO₂ economy

The Southeast Direct Air Capture (SEDAC) Hub is advancing plans for commercial direct air capture deployment in Mobile County, Alabama. Led by the Southern States Energy Board, the project brings together technology developers, engineering firms, universities, and regional partners to connect atmospheric carbon capture with infrastructure, permanent geologic storage, and potential commercial uses.

The Southeast DAC (SEDAC) Hub supports the deployment of Direct Air Capture (DAC) technologies in northern Mobile County, Alabama. DAC is a process designed to reduce carbon dioxide (CO₂) levels in the atmosphere by capturing CO₂ directly from the air. The CO₂ is then stored safely and securely. The SEDAC Hub is one of five Topic Area 2 projects chosen by the federal government to receive funding in order to establish a regional DAC hub. 

How Direct Air Capture Works

Direct air capture (DAC) technologies separate carbon dioxide (CO₂) from ambient air. The captured CO₂ can then be directed to permanent underground storage or used in commercial applications.

SEDAC is exploring opportunities to support a regional CO₂ economy that includes geologic storage, sustainable aviation fuel, urea production, and enhanced hydrocarbon recovery.

Project Site & Engineering

The project team has established a primary site on approximately 40 acres associated with Tenaska’s Longleaf CO₂ storage development in northern Mobile County.

Aircapture has advanced front-end engineering and design for an initial DAC facility designed to capture 50,000 metric tons of CO₂ annually. Mitternight has progressed engineering for the supporting equipment and infrastructure needed to operate the facility. The team is also evaluating potential expansion to 500,000 metric tons per year.

Current Status & Progress

The team has submitted an Environmental Information Volume to the U.S. Department of Energy’s National Energy Technology Laboratory, supporting environmental review of the proposed project.

Aircapture has also demonstrated a commercial application of its technology at Almanac Beer Co. in Alameda, California, where CO₂ captured from the atmosphere is used in beverage production. This deployment provides an example of how DAC technology can serve commercial CO₂ markets.

In August 2026, the Board convened project partners and regional stakeholders in Mobile for an August 13–15 meeting that included project discussions and a tour of Alabama Power Company’s Plant Barry. These activities are helping advance the technical and commercial foundation for integrating DAC with regional infrastructure, storage and utilization opportunities, and future economic development.
