September 10 (Renewables Now) - US nuclear power-focused energy technology company Holtec International has formed a multi-gigawatt manufacturing joint venture with Eos Energy Storage to produce the latter’s next generation of aqueous zinc batteries.

Eos is a supplier of Znyth DC battery systems, which utilise the company’s zinc battery technology as an alternative to lithium-ion. The batteries have more than four hours of energy, are capable of 100% charge and full discharge and also can operate in temperatures ranging from -15 °C to 45 °C without heating or cooling. The units do not use rare earth materials and are fully recyclable.

The new JV, called HI-POWER, will make use of Eos’ automated battery manufacturing design and Holtec’s 30 plus years of automation and manufacturing experience. It will have its factory built in Pittsburgh, Pennsylvania.

“Although we continue to invest in our nuclear business and believe in the future of our small modular reactor program for low carbon baseload energy, we recognize that renewables must also play a critical role in reducing carbon emissions going forward,” stated Rick Springman, Holtec’s Vice President of International Projects.

A year ago, Holtec became a significant shareholder in Eos Energy Storage and the two initiated a partnership aimed at commercialising the Gen2 Eos Aurora DC battery system.
