Carbon capture technology moves toward power plant integration

Powered by $7.5 million in federal and state funding, chemical engineering researchers are advancing their iron-based coal direct chemical looping (CDCL) technology closer to commercialization.

Liang-Shih Fan, distinguished professor of chemical and biomolecular engineering and director of Ohio State’s Clean Energy Research Laboratory, pioneered the CDCL technology, which chemically harnesses coal’s energy and efficiently captures the carbon dioxide produced before it can be released into the atmosphere. His research team recently began two new projects co-funded by the Department of Energy’s National Energy Technology Laboratory and the Ohio Development Services Agency.

One of the projects is focused on completing the front-end engineering design of a 10 MWe (megawatts electric) CDCL large pilot plant. The Ohio State research team has successfully demonstrated a 25 kWth (kilowatts thermal) sub-pilot CDCL process for more than 1,000 hours of operation, testing a wide range of solid fuels from anthracite coals to lignite and biomass. One MWe can power approximately 750 homes.
