12 Comparison with Other Advanced Power Cycles The purpose of this chapter is to compare the supercritical CO2 cycle design with its primary competitors: the helium Brayton cycle and the steam Rankine cycle in its superheated and supercritical versions and to outline the advantages and drawbacks of each cycle as well as the range of applications. Comparison is focused on the achievable efficiencies for each cycle mentioned above and on cycle layout with respect to simplicity and compactness, which primarily determine capital cost. Since the helium Brayton cycle is a gas cycle like the supercritical CO2 cycle more attention is given to the comparison with this cycle.

The cycles will be compared on the same power basis. The reference power is 300 MWe.
