Infinity Turbine has developed a new system that uses electricity stored in a saltwater redox flow battery to produce clean drinking water from seawater. According to it, the technology can be used on cruise ships and cargo ships.
“The desalination system works on a brine flow battery cycle where ions move between two electrodes to store or discharge electricity without a membrane, which is typical of vanadium or bromine flow batteries,” Salgenx CEO Greg Giese said. pv magazine. “In this case, the method is used to remove salt from salt water or sea water. The system can use a renewable energy source such as solar power or a large wind turbine to charge the battery, making it both environmentally friendly and cost-effective.
According to Giese, the new desalination system is currently being developed in a laboratory environment, and is being tested in a real environment both on land and on ships.
The technology could allegedly be used on cruise ships and cargo ships, as well as advanced military operations, where desalination is a better answer than shipping in fresh water or using expensive reverse osmosis systems, according to Giesen.
“This is a game changer for the desalination industry,” Giese said. “Our system offers a sustainable and cost-effective way to produce fresh water from seawater, which is essential in areas where water scarcity is a major problem. We are excited to be at the forefront of this technology and look forward to working with partners to bring this solution to communities around the world.
The battery manufacturer said its saltwater redox battery has an energy density of 125.7 Wh/l. The company claims a material cost of $5/kWh, $257/kWh for system infrastructure, and a total system cost of $500,000, or $166/kW for a 3,000 kWh battery.
