Coupling photovoltaic, concentrated solar power, and wind technologies for desalination

This invention describes a land-based system for turning saltwater into fresh water. It combines a concentrated solar power (CSP) system with a solar trough field to generate steam, and a large photovoltaic (PV) system producing over 15 megawatts of electricity. Both the steam and the PV electricity are used to power the desalination process and pump the fresh water to consumers.

Why it matters: Since 2018, the cost of large-scale photovoltaic systems has continued to fall, making the >15 megawatts specified in the claims more economically feasible. This could improve the overall cost-effectiveness of integrating solar power for desalination.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedIndustrial solar thermal, PV, and desalination plant.
