The presents a simulation of three different configurations of super critical CO2 cycles: pre–compression, partial cooling, and recompression performed using commercially available software (Ebsilon). The highest thermal efficiency is obtained for the recompression cycle (35%). All three cycles operate at 700°C. In addition to enjoying the highest efficiency, the recompression cycle involves a moderate number of elements - just one heat exchanger more than the simplest cycle (Pre-compression).
