This strategic move combines two complementary technologies to deliver the most flexible, cost-effective long-duration energy storage solution available on the market. The combined platform will set a new industry standard for performance, sustainability, and affordability. This acquisition adds VoltStorage’s portfolio of patents and technical development work to ESS’ robust existing intellectual property base. Through the transaction, ESS also gains access to skilled personnel with deep electrochemistry, materials science, and technology development background.
ESS believes the combined capabilities will accelerate strategic growth, expand market reach, and position the company at the forefront of long-duration energy storage solutions.
The resulting solution will enable utilities, renewable developers, and industrial customers to discharge energy over extended durations to improve grid reliability and increase the usable value of intermittent renewable generation, delivering the industry’s lowest Levelized Cost of Energy (LCOE).
Key benefits of the combined technology:
-
Flexibility: Potential to address a wider range of diverse applications, from grid-scale storage to industrial microgrids.
-
Lowest Cost Long-Duration Storage: Leveraging abundant, sustainable materials to deliver superior economics.
-
Sustainability and Scale: Iron-based chemistry ensures environmental responsibility and operational safety.
-
Enhanced U.S. Manufacturing Platform: Deploys international development expertise at ESS’ American manufacturing facility
“This acquisition accelerates our mission to provide clean, reliable, and affordable energy storage solutions worldwide,” said Drew Buckley, CEO of ESS. “By combining decades of iron flow battery expertise across two companies at ESS, we are accelerating innovation to create the most advanced iron-salt battery platform for long-duration storage.”
