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.

CO₂ capture from the SMR flue gas stacks located in Plant 01 and Plant 09 of the facility. Combined flue gases from each of the two sources would be collected and transported by ducts to the carbon capture facility. The design of the capture facility is 2,100 – 2,200 tpd of CO₂, including the CO₂ captured from the SMRs and additional flue gas generated from the steam boiler supplying the CCS unit. The CCS unit is to be designed for a minimum 30% plant turndown, this is to ensure the operation of CCS unit when flue gas from Plant 01 is the only feed to the CCS unit. For the purposes of the study the carbon capture facility design, including flue gas pretreatment and downstream CO₂ compression and dehydration, is provided by licensor. Hatch designed the flue gas transportation from the stacks to the Carbon Capture and Sequestration (CCS) unit battery limit, flue gas pressure boosting and Balance of Plant (BOP) which includes all the utility and offsite systems
