Review of the Recent Chemical Looping Process Developments for Novel Energy and Fuel Applications

Driven by the need to develop cleaner and more efficient energy systems, an extraordinary array of chemical-looping-based process concepts have been proposed and researched over the past 10 years. An overview of these technology options, particularly those proposed/developed over the last 3 years, is presented in this paper. The focus, however, would be primarily on process-related aspects of such advanced chemical looping concepts for novel energy and fuels applications rather than aspects such as oxygen carriers, redox properties, and solid circulation/transport, which have been adequately covered in several other reviews.
