Eos. Positively ingenious.

Since our founding in 2008, Eos has been on a mission to accelerate the shift to clean energy with positively ingenious solutions that transform how the world stores power. Our breakthrough Znyth® aqueous zinc battery was designed to overcome the limitations of conventional lithium-ion technology. Safe, scalable, efficient, sustainable—and manufactured in the U.S.—it’s the core of our innovative systems that today provide utility, industrial, and commercial customers with a proven, reliable energy storage alternative.

But that’s just the start of how we plan to make a positive impact. Forging our ambition, originality, and resourcefulness into something that’s ever more ingenious, that resets how great is defined and forever alters the way things work, is what we strive to do each day. It’s how we imagine, make, and hone clean energy storage solutions that defy convention to not only get the job done, but to do it better.

At Eos, in our Edison, NJ headquarters and our Pittsburgh, PA manufacturing plant, we’re creating purpose-built systems that work without complication—economical to produce, quick to install, safe to run, and easy to maintain—in the heat of an arid desert or the center of a bustling city. We’re minimizing the impact of every input and output in the processes we employ to consistently drive the entire value chain—supply, manufacturing, and operation—to zero carbon and zero waste, for ever greener generation tomorrow. And we’re staying flat and fast and engaging all our talents and experience in every effort to remove the barriers to delivery and access. Because the world simply can’t wait. It’s time to charge forward.

To the people of Eos, it’s just that simple, that smart. With ingenuity, we can build a more positive future powered by abundant and affordable clean energy.
