Tenaska is developing a carbon capture and storage (CCS) project that would serve emissions customers in South Alabama. As proposed, carbon dioxide (CO2) emissions from these facilities would be captured and transported to geologically secure underground storage locations in Mobile County.

The Longleaf CCS Hub will help manufacturers, industrial producers and power generating facilities meet growing environmental requirements in a cost-effective, responsible manner. At the same time, CCS projects like this bring economic benefits to the community.

Over 35 years of experience

Our Timeline

Tenaska started developing the Longleaf CCS Hub in 2022, receiving a positive reception to the project from emitters in the region and state and local leaders. The project submitted its Class VI application to the U.S. EPA in May 2023, kicking off a multi-year permitting effort. As work advances, we look forward to continuing to grow our relationships in South Alabama.

In the Community


The Longleaf team presents details of the project at a May 2023 reception organized by the Mobile Chamber. The Longleaf project aligns with the Chamber’s goals to support existing business and attract new industry to South Alabama.
