Carbon Capture Costs: FEED & pre-FEED Cost Reports

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.

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.

Membrane Technology and Research Inc., with Technology Centre Mongstad, Dresser-Rand, Trimeric Corporation, and WorleyParsons/Advisian, is scaling up its advanced Polaris™ membranes for post-combustion CO₂ capture and testing them at engineering scale at TCM in Norway. The Polaris membranes, about 20 times more permeable than prior commercial versions, use a patented selective recycle design to boost CO₂ concentration in flue gas and lower capture costs. The project will design, build, and operate a modular membrane system for a six-month field test, including performance verification, steady-state operation, techno-economic updates, and integration studies with advanced compression technology.
