Could a solar desalination system make water cheaper than tap water?

A new solar desalination system takes in saltwater and heats it with natural sunlight. The system flushes out accumulated salt, so replacement parts aren’t needed often, meaning the system could potentially produce drinking water that is cheaper than tap water.

How does solar desalination work?

Solar desalination utilizes the sun's energy to extract fresh water from saline sources such as brine or brackish water. This process replicates the natural water cycle through evaporation and condensation.

Can Floating photovoltaic systems generate clean water from contaminated water?

Djalab, A. et al. A comprehensive review of floating photovoltaic systems: tech advances, marine environmental influences on offshore PV systems, and economic feasibility analysis. Sol. Energy 277, 112711 (2024). Javed, M. et al. Complete system to generate clean water from a contaminated water body by a handmade flower-like light absorber.

Could a solar desalination system turn seawater into drinking water?

Engineers at MIT and in China are aiming to turn seawater into drinking water with a completely passive device that is inspired by the ocean, and powered by the sun. In a paper appearing today in the journal Joule, the team outlines the design for a new solar desalination system that takes in saltwater and heats it with natural sunlight.

How can solar energy improve water production?

Intermittent water production could be addressed through combining solar energy technologies like photovoltaic (PV) cells 63 and phase-change materials 64 to store energy during the day and use it at night for water purification, enabling continuous, all-day solar-powered water production.

How does a concentrating solar power system work?

The concentrating solar power system converts almost 100% of the solar radiation into high-temperature heat, which is used to produce high-pressure steam to drive a membrane desalination process, yielding approximately 80 l m –2 h –1 of fresh water.
