A patented technology invented at the U.S. Department of Energy’s National Energy Technology Laboratory enhances chemical looping combustion by providing tri-metallic ferrite oxygen carriers that offer greater durability and better reactivity than traditional oxygen carriers. Tri-metallic ferrite oxygen carriers also eliminate agglomeration issues, improve reduction rates, and offer similar costs when compared to traditional oxygen carriers, with convenient preparation using readily available materials. This technology is available for licensing and/or further collaborative research from NETL.
Oxy-combustion power generation provides oxygen to the combustion process by separating oxygen from air. Chemical looping systems take advantage of oxygen internal to the process, cutting the large capital, operating, and energy costs associated with oxygen generation. However, the development of robust oxygen carriers is critical for the efficient operation and adoption of CLC technology.
