This paper summarizes the research on energy systems with chemical-looping combustion conducted in recent years, discloses the underlying mechanism of energy release of chemical-looping combustion, describes the trends of the key technology development, and presents the proposed chemical-looping combustion thermal cycles. This paper may provide a new direction to the synthesis of the next-generation energy system compatible with environment. %K chemical-looping combustion %K CO2 separation %K energy-environment system %U http://link.springer.com/article/10.1007/s11434-009-0121-7
