[Objective

]

To improve the comprehensive energy utilization efficiency of solar thermal power generation

this paper presents a novel linear Fresnel reflector(LFR) concentrated solar polygeneration system using supercritical carbon dioxide(S-CO

) Brayton cycle and organic Rankine cycle(ORC)

which is designed for producing electricity

fresh water and hydrogen. [Methods

]

By using the Ebsilon code

the operation performance of the polygeneration system is investigated. [Results

]

The results show that the output power and Brayton cycle efficiency of the polygeneration system are 50.0 MW and 44.0%

respectively. The hydrogen production rate and freshwater production rate of the polygeneration system are 18.34 kg/h and 311.61 t/h

respectively. The LFR solar section

Brayton cycle

ORC hydrogen production section and multistag

e flash desalination facility can achieve the coordinated operation effectively during a long term. [Conclusion

]

The economic performance evaluation results show that for the polygeneration system

its levelized costs of electricity

hydrogen and freshwater are 0.72 yuan/(kW·h)

28.8 yuan/kg and 7.75 yuan/t

respectively

revealing the economic feasibility of the polygeneration system.
