This clever battery stores renewable energy while turning saltwater into fresh drinkable water
Engineers have developed a dual-purpose battery system that simultaneously stores electricity from renewable sources and removes salt from seawater to create clean, drinkable water.
A specialized water-desalination battery uses sodium and chloride ions from saltwater to store and release energy. During the charging phase, the device pulls salt ions out of the water and traps them in the electrodes, leaving behind fresh water. When the battery discharges to provide power to the grid, the salt ions are released back into a separate wastewater stream.
