OPERATIONAL OPTIMISATION OF THE MAIN HEAT REJECTION UNIT OF CSP PLANTS BASED ON CARBON DIOXIDE MIXTURES

This research, developed in the framework of the SCARABEUS project, studies the off-design performance of transcritical power cycles running on CO2-SO2 mixtures in Concentrated Solar Power applications. The objective of this work is to identify optimum operational strategies that maximise net energy production when exposed to variable ambient temperature, with special focus on the operation of the Heat Rejection Unit (Air-Cooled Condenser).
