Saltwater flow battery for water desalination applications – pv magazine International


Infinity Turbine has developed a brand new system that makes use of electrical energy saved in a saltwater redox circulation battery to provide clear ingesting water from seawater. It stated the expertise could be used on cruise ships and cargo ships.

US-based Infinity Turbine has introduced that it has developed a brand new water desalination system that deploys a saltwater redox circulation battery from its subsidiary Salgenx.

“The desalination system works by utilizing a saltwater circulation battery cycle, which entails the motion of ions between two electrodes to retailer or discharge electrical energy and not using a membrane, which is widespread in Vanadium or Bromine circulation batteries,” stated Salgenx CEO Greg Giese. pv journal. “On this case, the method is used to extract salt from brine or sea water. The system can use a renewable power supply, akin to solar energy or a big wind turbine, to cost the battery, which making it environmentally pleasant and price efficient.

The brand new desalination system is at the moment being developed in a lab setting and shall be examined in a real-world atmosphere for stationary and marine vessel functions, in response to Giese.

The expertise can supposedly be used on cruise and cargo ships, in addition to superior base army operations, the place desalination is a greater reply than transporting contemporary water, or utilizing costly reverse osmosis system, in response to Giese.

“This can be a game-changer for the desalination business,” Giese stated. “Our system offers a sustainable and cost-effective method to produce contemporary water from seawater, which is essential in areas the place water shortage is a significant difficulty. We’re excited to be on the forefront of this expertise and stay up for working with companions to convey this answer to communities around the globe.

The battery producer says its saltwater redox circulation battery has an power density of 125.7 Wh/L. The corporate claims a cloth value of $5/kWh, $257kWh for system infrastructure, and a complete system value of $500,000, or $166/kW for a 3,000 kWh battery.
