The U.S. Department of Energy awarded Babcock & Wilcox Power Generation Group Inc. (B&W PGG) a $2.5 million award for Phase 2 development of iron-based coal direct chemical looping (CDCL) technology.
B&W PGG and The Ohio State University have collaborated on the development of the technology, which was developed and successfully tested at bench scale at OSU’s labs in Columbus, Ohio. B&W PGG is continuing research and testing at the B&W Research Center in Barberton, Ohio and OSU’s labs as part of the commercial design effort.
In Phase II of the project, B&W PGG and its collaborators will test the CDCL process at a laboratory scale.
CDCL is an advanced process for carbon dioxide (CO2) capture. It uses a design where coal reacts with iron oxide-based oxygen carrier particles. The chemical reaction converts the coal into a concentrated stream of CO2 for use in enhanced oil recovery or for permanent storage and reduces the iron oxide.
The reduced oxygen carrier particles are reoxidized in a second reactor where heat is liberated, which can be used to produce steam for power generation.
B&W PGG President and Chief Operating Officer J. Randall Data stated the company appreciates the DOE’s continued support of its research and development efforts.
“Innovative solutions to capture and sequester CO2 are essential to coal’s future as a clean energy option in the United States,” he said in a release.
