Eos Energy

Eos Energy Enterprises (NASDAQ: EOSE) is a US-based manufacturer of zinc-powered long-duration energy storage systems, founded in 2008 and headquartered in Edison, NJ. The company's flagship product is the Eos Z3™ battery module, built on its proprietary Znyth™ zinc hybrid cathode aqueous technology. Unlike lithium-ion batteries, the Z3 uses a water-based electrolyte, non-degradable bipolar electrodes, and a fully sealed polymer casing - making it inherently non-flammable, non-corrosive, and capable of 4 to 16+ hour discharge durations with less than 4% degradation over a 25-year lifespan. With over 200 patents pending, published, or issued, Eos has developed an end-to-end system stack including the Eos Cube and Eos Indensity™ (gigawatt-scale, high-density) configurations, as well as its DawnOS™ AI-enabled control software.

Eos manufactures its batteries at its "Ingenuity Park" facility in Turtle Creek, PA - a former empty building transformed into a world-class clean energy manufacturing hub with over 250 full-time employees on-site. The company has achieved 10-second battery manufacturing cycle times on its first fully automated production line and targets 8 GWh of annual capacity by 2027 under Project AMAZE (American Made Zinc Energy). Its supply chain features over 90% domestic content using five earth-abundant, widely sourced commodities, making it both FEOC-compliant and highly resilient to geopolitical supply disruptions that plague lithium-ion competitors reliant on critical minerals from overseas.

Eos is strategically significant to the US energy supply chain as one of the only fully commercialized, domestically manufactured alternatives to lithium-ion and lead-acid batteries for grid-scale, long-duration storage. With a $589 million order backlog and a $14.2 billion commercial pipeline (as of September 2024), Eos is positioned to support the growing demand for renewable energy integration, grid resilience, and microgrid deployment. Its backing from the US Department of Energy - via the first Title 17 battery loan closed under the current administration - alongside private investment from Cerberus Capital Management, underscores its critical role in America's energy independence and clean energy transition.
