CSP (Concentrated Solar Power) - Tower Solar Thermal Desalination Plant

摘要

The main goal of this paper is that achieve 1.48 US $/m~3 for LCOW (Levelized Cost of Water) and 0.016 US $/kWh_(th) for LCOH (Levelized Cost of Heat). For this goal, the paper suggests an integrated CSP (Concentrated Solar Power)-Tower Solar thermal desalination facility with steam storage. The plant includes heliostat area, solar receiver, and thermal desalination unit and steam storage system. When sun shine, steam that is produced from the CSP heliostat field will be sent to steam storage system and the thermal desalination unit via steam reducer. Also, extra heat will be again used to charge the steam storage during the peak hours. The fresh water that is output of the desalination unit will be for public utilization. The brine (excessively salty water) that is output of the desalination unit will be processed for to obtain precious minerals with ZLD (Zero Liquid Discharge) technologies. Assumptions that is to calculate unit price are type of return schedule, type of interest rates for every year; and amortization and taxation are ignored With these assumptions, the methodology achieves the goal with 1.48 US $/m~3 and 0.016 US $/kWh_(th) for 12 years return time, %3 interest rate without subsidizing.
