Design and optimization of stand-alone triple combined cycle systems using calcium looping technology

A stand-alone triple combined cycle system (TCCS), which mainly consists of a solid oxide fuel cell (SOFC), Brayton-Rankine combined cycles, and a syngas producer, is developed as a high efficiency power generation system with CO2 capture by adding a post-burner and using the specific water/heat exchanger networks. Based on optimal operating conditions by solving two optimization algorithms, the simulation shows that the total power efficiency of the stand-alone TCCS is up to 60.56% and its CO2 emissions per kWh of electricity is down to 7.18 gCO2.184
