Eos Energy Enterprises (NASDAQ:EOSE) (NASDAQ: EOSE) develops and deploys zinc-based energy storage systems designed for long-duration applications across grid-scale and commercial markets. Leveraging proprietary zinc hybrid cathode battery technology, the company’s modules deliver multi-hour discharge, high cycle life and nonflammable operation. These systems help utilities and independent power producers integrate variable renewable resources, manage peak loads and provide essential grid services such as frequency regulation and voltage support.
Founded in 2008 and headquartered in Edison, New Jersey, Eos Energy has transitioned from a technology startup to a publicly traded enterprise. The company completed its business combination with a special purpose acquisition entity in 2021 and now operates a fully integrated manufacturing campus in Middletown, Ohio. Eos is led by CEO Bill Watkins, an executive with extensive experience in clean energy deployment, and CTO Dr. Daryl Clinton, who oversees research, development and product innovation.
The company’s flagship product, the Z3 Flow Battery, features modular stacks that can be configured for durations ranging from two to six hours. Its aqueous zinc chemistry offers enhanced safety compared to traditional lithium-ion systems, while maintaining competitive total cost of ownership through low degradation under deep-cycle conditions. Eos also provides digital asset management tools that enable remote monitoring, predictive maintenance and performance optimization for both front-of-the-meter and behind-the-meter installations.
Eos Energy serves customers across North America and Europe, partnering with electric utilities, renewable developers and engineering firms to support a broad portfolio of energy storage projects. With ongoing investments in pilot deployments, strategic alliances and manufacturing scale-up, Eos aims to meet the growing global demand for reliable, dispatchable and sustainable energy storage solutions.
