Awards highlight ESS’ commitment to innovative technology and solving America’s tough energy challenges including rapidly growing AI data center demand, increasing intermittent generation sources, and grid reliability.
WILSONVILLE, Ore.–(BUSINESS WIRE)–ESS Tech, Inc. (ESS) (NYSE: GWH) has been named one of TIME’s Top GreenTech Companies in America 2025 and one of Fortune’s Most Innovative Companies in America 2025.
Kelly Goodman, Interim CEO, said:
We are honored to be recognized as a leader in green technology and innovation,
“This recognition underscores our commitment to research and development, and the commercialization of safe and sustainable iron flow technology. Our commitment is reflected in our considerable IP portfolio and out-of-the-box approach to delivering gigawatt scale long-duration energy storage projects. Our new Energy Base™ solution leverages our proven core technology to meet the needs of rapidly growing AI data centers and an increasingly electrified society.”
ESS’ considerable intellectual property portfolio played a key role in evaluation for both awards. ESS is a global leader in the long-duration energy storage sector. The company’s commitment to innovation, research and development is reflected by over 100 patents awarded and 214 pending patent applications for iron flow technology.
Recent advancements include a 20% increase in electrolyte energy density, improved storage capacity and reduced auxiliary load requirements for the company’s Energy Center product line in comparison to earlier ESS products. The company’s new Energy Base solution focuses on modularity that decouples power and energy capacity, which lets customers scale each one separately to meet the requirements of their use cases. By leveraging ESS’ 22-hour battery module capability, the Energy Base is expected to deliver gigawatt-scale long-duration energy storage at energy densities superior to lithium-ion technology. With 22-hour projects available for deployment as soon as 2027, the Energy Base is expected to meet the energy storage needs of data centers and enable 24/7 clean energy.
