Babcock & Wilcox Power Generation Group (B&W PGG), a subsidiary of The Babcock & Wilcox Company (B&W), has secured $2.5m in funding from the US Department of Energy (DOE) for Phase 2 development of coal direct chemical looping (CDCL) technology, an advanced process for clean power generation and carbon dioxide (CO2) capture.
The Ohio State University (OSU) and B&W PGG researchers have collaborated for the development of CDCL technology, which is potentially lower cost than other CO2-capture technologies.
B&W PGG president and COO J. Randall Data said, "Innovative solutions to capture and sequester CO2 are essential to coal’s future as a clean energy option in the United States.
"We appreciate the DOE’s continued support of our research and development efforts and look forward to adding CDCL technology to B&W PGG’s suite of advanced power generation systems and CO2 capture options."
The technology was developed and successfully tested at bench scale at the OSU’s labs in Columbus, Ohio.
Research and testing for the CDCL technology are progressing at the B&W Research Center in Barberton, Ohio and at OSU’s labs.
B&W said that the latest technology uses a unique fuel reactor design where coal reacts with iron oxide-based oxygen carrier particles.
The chemical reaction changes coal into a concentrated stream of CO2, which will be used in enhanced oil recovery or for permanent storage, and reduces the iron-oxide.
The diluted oxygen carrier particles are re-oxidised in a second reactor where heat is released, which can be used to produce steam for the generation of power.
B&W PGG’s experience in circulating fluidised bed and bubbling bed technology was utilised in the development of the commercial scale design.
