ESS Tech (GWH) announced a collaboration framework with Salt River Project and Google (GOOG) for Project New Horizon to advance energy storage at SRP's Copper Crossing Energy and Research Center in Florence, Arizona. Project New Horizon is a five-megawatt, 50 megawatt hour system that will deploy ESS' iron flow Energy Base technology and represents a significant commercial validation milestone for the company's utility-scale platform. The pilot is expected to support SRP's evaluation of emerging non-lithium LDES technologies.

ESS Tech announced that Randall "Randy" Selesky has joined the company as Chief Commercial Officer. In this role, Selesky will lead global commercial strategy, sales, marketing, product management, and business development initiatives as ESS advances commercialization and scales deployment of its long-duration energy storage solutions worldwide. Prior to joining ESS, he served as the CCO at VoltStorage.

ESS Tech announced the acquisition of the intellectual property and assets of VoltStorage GmbH, a pioneer in iron-salt battery technology. "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." Through the transaction, ESS also gains access to VoltStorage's patent portfolio and key personnel. The financial terms of the deal were not disclosed.

ESS Tech announced the execution of a $9.9M contract with Concurrent Technologies Corporation and the United States Air Force Research Laboratory for a large capacity energy storage system at the U.S. Clear Space Force Station in Alaska. Under the contract, ESS will deploy up to 27 MWh of its American-made iron flow battery systems to support operations at Clear Space Force Station. "This project is a significant validation of ESS battery technology and its ability to provide reliable energy every day and support grid resiliency when it matters most," said Drew Buckley, CEO of ESS. "The Department of Defense is actively seeking long duration resilient microgrids to improve readiness, with a keen interest in 'Made in USA' software and systems to reduce risk of foreign cyber security vulnerabilities. We believe this award will further unlock long duration storage opportunities with the DoD and the growing microgrid market."
