Solar-Powered Desalination Produces Drinking Water and Recovers Valuable Minerals

Researchers at the University of Rochester, led by Professor Chunlei Guo, have developed an innovative solar-powered desalination system that converts seawater into drinking water while recovering nearly all salts in solid form. Unlike traditional desalination methods that create environmentally harmful brine, this system uses black metal panels etched with femtosecond lasers. The laser-textured surfaces make the panels highly absorbent of sunlight and extremely effective at wicking water. Water is pulled across the panel, evaporates, and leaves the salts to slide into untreated regions, preventing clogging and maintaining continuous operation. This technology not only produces fresh water but also isolates valuable minerals, including lithium, which is essential for lithium-ion batteries. In tests using water from three oceans and the Great Salt Lake, the system extracted almost all salts and recovered about 50% of lithium from the residual minerals. The panels’ design allows for scalable applications, offering potential global benefits for drinking water access and sustainable mineral sourcing. Funding came from the National Science Foundation, the Bill & Melinda Gates Foundation, and the Worldwide Universities Network. While the technology is still in the proof-of-concept stage, its innovative approach could reduce energy consumption and environmental impact compared to conventional desalination.

💁🏻‍♀️ TIL: Kelsey Pfendler, 31, left #Monterey, #California on May 21, in an attempt to become the youngest woman to row solo and unassisted to #Hawaii. 🚣

⛈️ In her first week, she’s already faced storms, lost her freshwater supply, and is relying on tortillas and peanut butter until the #sun returns to power her solar desalinator. The current solo record is 86 days.

💧 New solar-powered system produces fresh drinking water from seawater without chemical additives.

☀️ The technology uses black metal etched with lasers to absorb sunlight efficiently and a self-cleaning surface that separates salts.

💎 Leftover salts are transformed into useful materials, including lithium for rechargeable batteries, addressing both water shortages and mineral demand.

Corpus Christi Faces Severe Water Shortage Amid Drought and Growing Industrial Demand

Corpus Christi, Texas, and the surrounding Coastal Bend region are facing a significant water shortage that has impacted residents, businesses, and industrial operations. Since August 2024, restrictions have limited lawn watering and other non-essential uses, with potential for stricter limits if drought conditions persist. The city relies on the Nueces, Lavaca-Navidad, and Colorado river basins for most of its water, with reservoirs such as Choke Canyon and Lake Corpus Christi currently at just 8% capacity. Industrial expansion, especially at the Port of Corpus Christi, has sharply increased water demand, and new water sources have not been developed since 2016. Plans for a desalination plant were abandoned due to rising costs, leaving the city to explore alternative measures. These include groundwater wells, reclaimed wastewater for industrial and irrigation use, and potential purchases from a nearly completed desalination facility. Long-term solutions will require careful planning, significant investment, and consideration of climate change impacts to ensure reliable water availability for both residents and industries.

Poisonous chemical added during water treatment by desalination water plants:

Sodium metabisulfite

It is also called: E223 and "Metabisulfito de sodio".

Forced to behave, saltwater generates power. Fukuoka engineers turn desalination brine into 880 MWh annually, sustaining 300 households. How does osmotic power differ from traditional renewables? #Desalination #CleanEnergy #EcoTech

@karabaic With the increasingly wild swings in climate, #desalination makes pragmatic sense. #SodiumIon #batteries are a byproduct of desalination plants that haven't been pursued, nearly enough. Even wave conversion to energy is in the mix with these plants, with other benefits to be added.
