1_11i/2013Inside Cover: Review of Oxygen Carriers for Chemical Looping with Oxygen Uncoupling (CLOU): Thermodynamics, Material Development, and Synthesis (Energy Technol. 11/2013)

Chemical Looping with Oxygen Uncoupling: The cover picture illustrates the process of chemical looping with oxygen uncoupling (CLOU), which is an emerging 3rd-generation carbon dioxide capture and storage (CCS) technology. In CLOU, molecular oxygen is provided at elevated temperatures by the decomposition reaction of a solid oxygen carrier, thus, effectively combusting a solid fuel in an oxyfuel mode. In the Review by Christoph Müller and colleagues at ETH Zürich on page 633, the authors review recent advances in the development of new oxygen carriers for CLOU. In particular, the physical, thermodynamic, and chemical properties of the new materials are reviewed and their synthesis strategies are discussed in detail.
