Holtec International and Eos Energy Storage, LLC Team up to Establish HI-POWER, a Multi-Gigawatt Aqueous Battery Manufacturing Facility

Holtec International and Eos Energy Storage (Eos), the developer of Znyth®DC battery systems, announce the formation of HI-POWER, LLC, a multi-gigawatt manufacturing joint venture to mass produce state-of-the-art aqueous zinc batteries for industrial-scale energy storage. 

HI-POWER is poised to leverage Eos’s innovative non-flammable battery technology and Holtec’s manufacturing automation know-how to operate a manufacturing facility that can meet the burgeoning demand for high- quality batteries for storage of carbon-free energy from renewable energy and nuclear power plants. The HI-POWER plant will be located close to the Pittsburgh-based Holtec Manufacturing Division (HMD), which custom manufactures capital equipment for the global power industry. Small scale production has been successfully demonstrated; large scale production is expected to begin in late November.

The HI-POWER battery installation will serve to store surplus power from Holtec’s SMR-160 small modular reactors to deliver power to the grid during peak periods of demand making the notion of microgrid and distributed generation a truly viable concept.

“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,” said Joe Mastrangelo, Chief Executive Officer of Eos.

The Eos batteries are zinc hybrid cathodes, which provide a safe, sustainable and scalable alternative to their lithium ion counterpart; they also operate across a wide temperature range without HVAC and the risk of fire or explosion. The current generation batteries feature over four hours of energy delivery from 100 percent charge to full discharge and can operate in -15ºC to 45ºC temperature range without thermal conditioning. Additionally, the batteries are comprised of high-volume core commodity components, use no rare earth materials and are fully recyclable. They are modular, fungible and fire-immune enabling in-building (sheltered) as well as unsheltered installation in the size and capacity of the user’s choosing. 

In addition to partnering in the HI-POWER manufacturing program, Holtec’s engineering organization will collaborate with Eos in the development of the next generation batteries using the Company’s cutting-edge technologies in Computational Fluid Mechanics and automation. 

“We have entered the battery industry to provide the means to store large quantities of electrical energy from nuclear, solar and other renewable energy generation facilities and deliver power to the user on demand. The availability of a suitably sized battery-powered energy storage plant will make our SMR-160 reactor even more valuable to our customers. To cut unit production cost, we plan to expand our facility as warranted by the demands of the market,” says Dr. Kris Singh, President and CEO of Holtec International.

Holtec will also collaborate with Eos in sales and marketing of HI-POWER produced batteries.  

“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 Dr. 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.

Holtec, Energoatom and SSTC enter into a Trilateral Consortium Partnership to advance the SMR-160 nuclear reactor for deployment across Ukraine

Mitsubishi Electric commits to stage two of SMR-160 Alliance with Holtec with a large resource commitment 

June 10, 2019 Camden, NJ: Ukraine’s national nuclear operator NAEK Energoatom, the nation’s State Scientific and Technology Center (SSTC), and Holtec International ratified the creation of a consortium partnership that binds the three companies into a cooperative undertaking to chaperone the deployment of the SMR-160 small modular reactors in the country. The Consortium is a US company registered in Delaware with each of the three parties owning allotted shares. The Consortium’s technology operation center will be based in Kiev, Ukraine. This Consortium will give fresh impetus to realize the objectives of the MOU signed by Energoatom and Holtec last year that envisages building of six SMR-160s at the country’s Rivne nuclear station site. President Yuriy Nedashkovskyof Energoatom and Dr. Kris Singh of Holtec signed the Consortium document in person with SSTC President Igor Shevchenko signing remotely. The signing ceremony was attended by senior Holtec officials and delegations from Mitsubishi Electric Corporation (MELCO), US Department of Energy and Energoatom. Speaking at the signing ceremony, Mr. Nedashkovsky spoke of the dominant role played by nuclear in Ukraine’s energy mix providing over 50% of the nation’selectric generation and expressed the confidence that SMR-160s will provide a clean energy successor to the nation’saging fleet of coal-fired plants. He assured the attendees that there is a national consensus in Ukraine to build SMRs which has been reached after extensive research and consultations.
