In this paper, two new combined cycle systems with/without CO2 capture based on methanol indirect combustion are developed, which have significantly higher efficiency than methanol fueled conventional combined cycle. The performance of the new systems is compared with conventional combined cycle to identify the potential of methanol indirect combustion. The systems are modeled by using Aspen PlusTM and GTProTM. Exergy analysis and the principle of cascade utilization of chemical exergy reasonably explain the improved efficiency of the new systems. Other merits of the combined cycle systems based on methanol indirect combustion are discussed and their promising commercial application aspects are pointed out.
