US-based Salgenx has developed a scalable redox circulate battery with two separate tanks of electrolytes, one in every of which is salt water. In contrast to different batteries that circulate, the brand new gadget doesn’t have a membrane, promising nice beneficial properties within the quantity of storage.
US-based tech startup Salgenx has unveiled a scalable saltwater circulate battery for purposes in renewable power, telecommunication towers, oil properly pumps, agriculture irrigation pumps, and greenhouse irrigation or lighting. The batteries are appropriate for standalone storage or with photo voltaic or wind energy.
“It’s properly suited to solar energy storage, with the additional benefit of photo voltaic thermal storage in a salt water electrolyte tank,” stated CEO Gregory Giese. pv journal.
The producer says that the brand new battery has an power density of 125.7 Wh/L. It requires two giant tanks full of fluid electrolytes, one in every of which is saltwater and the opposite a proprietary electrolyte. Fluids are circulated via the electrodes, which regulate the enter and output of electrical energy from the battery.
The answer could be scaled by including extra electrodes and extra electrolyte tanks. Salgenx additionally gives the answer in 250 kW, 3 MWh, 6 MWh, 12 MWh, and 18 MWh configurations. The circulate battery doesn’t have a membrane, not like most redox circulate batteries.
“The lack of the membrane can save some huge cash in buying, upkeep, and working prices,” Salgenx stated on its web site.
The corporate claims that the fabric prices $5/kWh, $257kWh for the infrastructure system, and a complete system value of $500,000, or $166/kW for a 3,000 kWh battery. The know-how is alleged to have a lifespan of greater than 25 years and a roundtrip effectivity of 91% at 10 mA/sq. centimeter.
A salt water tank can be utilized concurrently for warmth storage, mixed with a warmth pump utilizing carbon dioxide as a refrigerant.
“Usually the thermal financial savings utilizing a warmth pump and the next COP (coefficient of efficiency), can double the financial savings price of electrical energy,” claims the corporate.
Salgenx develops the know-how and sells licenses to third-party producers to commercialize the options.
