Carbon Capture Costs: FEED & pre-FEED Cost Reports

Southern Company Services, with Linde Gas North America, is conducting a FEED study for a commercial-scale CO₂ capture system using Linde-BASF’s advanced aqueous amine technology at an NGCC plant of at least 375 MWe. The project will evaluate Alabama Power’s Plant Barry and Mississippi Power’s Plant Daniel to select the optimal host site, define project requirements, optimize process design, and deliver engineering packages along with a cost and schedule estimate within 15% accuracy. The study will build on prior feasibility work and site-specific testing.

Linde Inc., with Linde Engineering Americas and BASF, is conducting an initial engineering design for a 3,500 tonnes/day CO₂ capture plant using Linde-BASF’s advanced aqueous amine technology at a Linde-owned steam methane reforming facility. The project will define integration options, establish project requirements, optimize process design, and develop engineering, cost, and schedule packages. BASF will provide the technology design, LEA will deliver detailed engineering and constructability assessments, and Linde will lead techno-economic, environmental, and safety analyses in coordination with the SMR plant operators.

Cleco Power (Cleco) performed a three-phase front-end engineering and design (FEED) study evaluating installation of a carbon dioxide (CO2) Capture System at Madison Unit 3 (MU3), Project Diamond Vault (DV) The work was performed under a Department of Energy (DOE) grant DE-FE0032165. The FEED study included three phases: (1) a feasibility phase which sought to define the scope of the project, (2) a pre-FEED phase which sought to develop a detailed cost estimate, and (3) a final FEED phase which sought to develop the project to be ready to move into execution. The FEED study was completed by Cleco, Mitsubishi Heavy Industries America (MHIA), and Sargent & Lundy, LLC (S&L) with oversight provided by the Louisiana Economic Development (LED). The feasibility phase was completed in February 2023, which was followed by the pre-FEED phase which concluded in January 2024. The project subsequently entered the final FEED phase, during this phase Cleco made the decision to stop work on the FEED study due to market conditions which resulted in a project that was not economically viable at the time.
