EOS Energy

EOS Energy is a publicly traded energy storage company founded in 2008 that manufactures zinc-based battery systems as an alternative to lithium-ion for grid-scale and commercial applications. The company's Z3 battery technology uses zinc chemistry that is non-flammable, non-toxic, and sourced from abundant domestic materials, addressing safety and supply chain concerns associated with lithium-ion systems. EOS batteries are designed for two-to-twelve-hour discharge durations needed for daily grid cycling, offering competitive total cost of ownership compared to lithium alternatives when considering the full system lifecycle. The company operates manufacturing facilities in Pittsburgh and has secured purchase orders and deployment projects with utility and commercial customers. EOS is publicly traded on Nasdaq and has received support from the US Department of Energy as part of national efforts to diversify the battery storage supply chain. As the energy storage market grows and lithium supply concerns persist, zinc-based alternatives from companies like EOS offer a domestically manufacturable complement to lithium-ion storage.
