“…As the project incorporates a high capacity recuperator, which helps to decrease the temperature of the working fluid before the compression stage and recovery of the heat after this stage, the waste heat is significantly reduced in the power block and the temperature obtained in the wastewater flow is about 55 C, producing a lower evaporation rate for the base case compared with those in Ref. 40.…”

“…39 Figure 6 shows a conceptual diagram of the system based on the previous research of Hosseini Araghi, Khiadani, 27 and Araghi, Khiadani. 40 The inlet flow is wastewater coming from the town at an ambient temperature of 23 C and a flow rate of 250 000 kg/h. The wastewater is heated using the waste heat removed before the compression stage of the CO 2 in the power block.…”

This paper proposes the use of a hybrid 5 MW power generation system combining concentrated solar thermal and solar photovoltaic technology where the efficiency of the power block is increased by taking advantage of hot water from a low-temperature geothermal source. Aiming at a case study for Winton in Queensland the pertinent meteorological data are used for our simulations.In addition, the paper analyzes the feasibility of including a thermal desalination technology that uses the waste heat from the power block for producing clean water from wastewater. Our design replaces the traditional dry cooling system with a water-cooled heat exchanger to remove the waste heat from the power block. Finally, this work explores the ratio of concentrated solar thermal and photovoltaic electricity production that optimizes the levelized cost of electricity and water production. the results indicate that the incorporation of the desalination system does not produce a significant increase in this value, and the optimal ratio of electricity production is obtained when the photovoltaic system contributes to 27.5% of the total electricity generation. Our water production cost can be as low as 40 ₵/m 3 while for the combined system our minimum levelized cost of electricity figures out at 12.4 ₵/kWh to generate the base load with thermal storage.
