100% Safe Constructed with environmentally benign, non-toxic materials, the Aurora system has no mode of catastrophic failure and is safe to locate in urban areas

Cost of Incumbents

Traditionally, non-pumped hydro energy storage has been too expensive to compete with incumbent solutions used for peak generation and delivery. Today’s batteries, such as Lithium-ion and lead-acid, rely on rare earth metals and expensive manufacturing techniques or simply don’t last long enough to be cost effective on the electricity grid. Eos utilizes abundant materials such as zinc and low cost manufacturing processes like injection molding to keep costs low. With a 30-year life, Eos is can provide peak electricity at a levelized cost of $0.12-0.17 per kWh—substantially less than conventional gas turbines and competing energy storage technologies.

Applications

Energy storage has value-added applications across the entire energy supply chain and is also the enabling technology for independent microgrids. Applications are bundled according to how the battery is used and, equally important, where it is located. Eos is working with its Genesis partners to evaluate and pursue applications where its Znyth™ technology can create value and reduce cost to create a compelling business case and return on investment for the customer.
