An integrated system combining chemical looping hydrogen generation process and solid oxide fuel cell/gas turbine cycle for power production with CO2 capture

► CLHG process produces hydrogen with inherent CO2 separation. ► SOFC/GT cycle is integrated with coal gasification and CLHG process. ► The plant has an electrical efficiency ∼43% (LHV) and zero-CO2-emission. ► Parameters such as SOFC temperature influence the plant performance.
