Eos Aurora® | Grid-Scale Energy Storage

Order-now-banner2

The Eos Aurora® 1000│4000 is a low-cost DC battery system designed specifically to meet the requirements of the grid-scale energy storage market. With 4 hours of discharge capability, immediate response time, and modular construction, the Aurora® system can be scaled and configured to reduce cost and maximize profitability in utility, commercial and industrial, and military market segments.

low cost
Low Cost/kWh At $160/kWh (for volume purchases of 40MWh or more) and $200/kWh (for orders less than 40MWh) for the DC system, Eos is cost competitive with existing peak generation technologies
long life
Extremely Long Lived Aurora® is projected to last 5,000 cycles for a 15-year calendar life
High density
High Energy Density Each 250kW subsystem is 11 ft. high, 11 ft. wide, and 16 ft. long and Eos offers several layout options for a 1MW|4MWh footprint.
Efficient
High Energy Efficiency With a round trip efficiency of 75% in full depth of discharge applications, Aurora® is one of the most efficient long-duration energy storage solutions
Safe
100% Safe Non-flammable aqueous electrolyte has no flashpoint; non-hazardous and non-corrosive when shipped
Products Aurora®

The Eos Aurora® 1000│4000 offers many competitive advantages including a 100% depth of discharge standard use-case and a wide temperature range to enable implementation without the use of HVAC.

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.

Eos Technology

Znyth® | Zinc Hybrid Cathode Technology

Eos’ novel Znyth® (zinc hybrid cathode) battery technology employs inexpensive, widely available materials within a robust, scalable design to achieve long-life and extremely low-cost. After 10 years of development, Eos’ Znyth® technology is built on 21 patents and patent applications with over 600 claims covering cell configuration and architecture, cathode design and materials, electrolyte and electrolyte additives, battery management systems, and low-cost manufacturing processes. The result is a battery technology with unparalleled performance and market reach.

 

Some of Znyth’s® Key Advances Include:

Titanium current collector with proprietary ceramic coating is permanently conductive, non-corrosive, and self-healing
Aqueous, near neutral pH electrolyte is non-dendritic and does not absorb CO2, eliminating carbonate clogging issues
Proprietary electrolyte additives and buffering agents enhance zinc solubility and plating to improve energy density and run-time
Hybridization of cathode chemistries and electro-active catalysts improves power density and roundtrip efficiency
Highly standardized manufacturing processes such as metal stamping and injection molding to keep manufacturing costs low

Guiding Philosophy

Eos’ objective is to develop a product that solves real business problems. To achieve this, Eos is developing energy storage solutions that address the fundamental requirements of the marketplace and compete economically with incumbent solutions used on the grid today. With these guiding principles in mind, Eos has developed and is now commercializing a revolutionary rechargeable zinc hybrid cathode battery technology we call Znyth®.
