Holtec, Eos create battery manufacturing joint venture

Eos Energy Storage and energy equipment firm Holtec International are creating a joint venture to produce Eos’ next generation of large-scale zinc batteries.

Hi-Power LLC will combine Eos’ automated battery manufacturing design and Holtec’s infrastructure experience to build a facility in Pittsburgh. The multi-GW manufacturing site will produce the new aqueous zinc batteries.

“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,” Eos CEO Joe Mastrangelo said in a statement.

New Jersey-based Eos’ next generation batteries are zinc hybrid cathodes which not only provide an alternative to lithium-ion, but they also operate across a wide temperature range without HVAC and without the risk of fire or explosion, according to the company. Eos says the batteries feature over four hours of energy, are capable of 100 percent charge and full discharge and can operate in -15 °C to 45 °C temperatures without heating or cooling.

Holtec will collaborate on Eos battery sales. The Florida-based firm is known as a global energy equipment supplier and also for salvaging parts from decommissioned nuclear power plants.

“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,” said Kris Singh, president and CEO of Holtec International.
