Project Description

FuelCell Energy, Inc. (FCE) is partnering with AECOM Technical Services, Southern Company Services, and Alabama Power Company to continue development of its novel system for separation of carbon dioxide (CO2) from greenhouse gas emission sources using FCE’s patented Combined Electric Power and Carbon Dioxide Separation (CEPACS) system. The CEPACS system is based on an electrochemical membrane (ECM) technology. The driving force for CO2 separation is electrochemical potential and results in simultaneous power production and CO2 separation. The membrane consists of ceramic-based layers filled with carbonate salts, and separates CO2 from the flue gas with a selectivity of 100 percent over the nitrogen present in the gas. Because of fast electrode kinetics, the low CO2 concentration normally found in pulverized coal (PC) plant flue gas is suitable for ECM operation. The planar geometry and modularity of the ECM technology allows for easy configuration into large-size systems suitable for deployment in PC plants. In this project, FCE will design and fabricate a small pilot system (nominal 3-MWe equivalent) and test the system for at least two months on actual flue gas from a slipstream of flue gas from the Barry Generating Station, the host site. A techno-economic analysis and an environmental, health, and safety study of the system will be performed. The project objective is to verify that the CEPACS system can achieve at least 90 percent CO2 capture from PC plant flue gas with 95 percent CO2 purity at a cost of $40/tonne of CO2 captured and at a cost of electricity 30 percent less than baseline CO2 capture approaches.

Predecessor Project: FE0007634

Project Benefits

The CEPACS system produces power while capturing CO2, reduces nitrogen oxide (NOx) emissions, and uses modular configurations to minimize its footprint. Small pilot-scale testing of the CEPACS system will pave the path toward commercial deployment of large-scale, coal-based ECM systems for carbon capture applications by 2025, directly supporting the U.S. Department of Energy’s Carbon Capture Program goals. This project may also enable small-scale, near-term applications for incremental carbon capture from coal-based sources and natural gas sources.
