Polk Power Station Carbon Capture Project

The Polk Power Station Unit 2 Carbon Capture Project is a large-scale post-combustion capture retrofit study led by Tampa Electric Company (TECO) at its 1,190 MW natural gas combined cycle plant in Mulberry, Florida. The project completed a detailed Front-End Engineering Design program under U.S. Department of Energy Award DE-FE0032224, with total funding of approximately $7.0 million, including $5.6 million in federal support and $1.4 million in cost share from TECO. The capture system is designed to achieve 95 percent CO₂ removal, equating to roughly 3 million tonnes of CO₂ captured annually, targeting one of TECO’s most heavily utilized generating assets, which supplies about 30 percent of the company’s total electricity output. The project consortium includes ION Clean Energy as the carbon capture technology provider using its ICE-31 advanced solvent system, Sargent & Lundy as EPC engineering partner, Koch Specialty Plant Services supporting absorber and column design, and Siemens Energy responsible for CO₂ compression and dehydration systems. Key outcomes from the FEED confirmed site suitability, technical feasibility, and constructability for full-scale deployment, producing an AACE Class 3 cost estimate and a complete engineering execution package.
