Carbon Capture Costs: FEED & pre-FEED Cost Reports

Bechtel National Inc., with the Electric Power Research Institute, is conducting a FEED study to retrofit Panda Power Funds’ 758 MWe natural gas combined cycle plant in Sherman, Texas, with a post-combustion CO₂ capture system. Using an open-access design and a conventional amine absorber-stripper system with a non-proprietary solvent such as MEA, the project targets CO₂ capture for enhanced oil recovery.

Milton R. Young Station Unit 2 is conducting a FEED study to add a post-combustion CO₂ capture system using Fluor’s Econamine FG Plus™ technology to its lignite-fueled power plant in North Dakota. The design targets 3.6 million tonnes of CO₂ captured annually—twice the scale of the largest existing facility—while integrating advanced heat recovery, aerosol and solvent degradation controls, and cold-climate optimization to achieve the lowest levelized cost of capture at world scale. The study will deliver detailed design, cost, and performance data for financing, permitting, and final project scheduling.

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.
