This paper presents an extended chemical-looping combustion (exCLC), which may be the core process in an advanced power generation system with CO2-capture that cogenerates hydrogen and electrical power. This paper focuses on the description of the exCLC and its novelty compared to the classic chemical-looping combustion (CLC), which is known as all efficient alternative for CO2-capture. In CLC. a solid oxygen carrier circulates between two fluidised-bed reactors and transports oxygen from the combustion air to the fuel, thus, the fuel is not mixed with air and an inherent CO2 separation occurs. In addition to the classic CLC, the exCLC inherently separates the CO2 and hydrogen, that is produced by the process. A thermo-chemical study of the exCLC provides the required operating conditions of each step. The results indicate that the production of hydrogen is possible as well as an inherent separation of hydrogen and CO2.
