New joint venture HI-POWER will manufacture gigawatts of Eos aqueous zinc batteries in Pittsburgh

Holtec International, a supplier of equipment and systems for the energy industry, and Eos Energy Storage, a supplier of Znyth DC battery systems, in an expansion of their strategic partnership, announced the formation of HI-POWER, a multi-gigawatt manufacturing joint venture to produce Eos’s next generation of aqueous zinc batteries.

HI-POWER will leverage a combination of Eos’s proprietary, automated battery manufacturing design and Holtec’s more than 30 years of market leading automation and manufacturing experience to build a new manufacturing facility in Pittsburgh, Pennsylvania.

“We are excited to partner with Holtec to establish a world-class manufacturing facility and also work together to bring our DC system to Holtec’s existing customer base in addition to meeting the rapid global growth of battery storage,” said Joe Mastrangelo, CEO of Eos.

The Eos next generation batteries are zinc-hybrid cathodes, which not only provide a safe, sustainable and scalable alternative to lithium-ion, they also operate across a wide temperature range without HVAC and without the risk of fire or explosion. Eos batteries feature over four hours of energy, are capable of 100% charge and full discharge and can operate in -15 °C to 45 °C temperatures without heating or cooling. Additionally, the batteries are comprised of high-volume core commodity components, using no rare earth materials, and are fully recyclable. Its modular flexibility and safety attributes allow for in-building installations, as well as plug-and-play outdoor container solutions.

“Holtec will team with Eos in making HI-POWER one of the largest battery manufacturers in the U.S., leveraging Holtec’s years of manufacturing experience and Eos’s 10+ years in developing the best market alternative to lithium-ion,” stated Dr. Kris Singh, president and CEO of Holtec International.

Holtec will also collaborate on Eos battery sales, providing HI-POWER with the order volume needed to continue to drive cost efficiencies.

“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. A key limitation of renewables has been variability in production, which can be levelized with the DC battery system, helping drive a fundamental shift in the renewables market,” stated Rick Springman, Holtec’s Vice President of International Projects.

Eos, founded in 2009, has conducted over 15 million hours and two million test cycles in developing its Znyth DC battery system and has produced over 3,000 batteries for industrial, utilities and micro-grid applications across four continents.
