Eos has developed a low-cost zinc-based battery with a projected lifetime of around 30 years (10,000 cycles).
Northern Power Systems has in turn developed an integrated energy storage system (ESS) combining the Eos Aurora DC battery system with power converter technology and controls from Northern Power. The resulting turnkey ESS solution is designed to provide 4 hours of usable energy from modular 250 kW battery units, scalable up to multi-MW level.
The combined ESS utilises Northern Power’s FlexPhase inverter technology, with power output ranging from 500 kW to 2,000 kW. The key features of this inverter technology are:
Eos’ unique aqueous zinc hybrid cathode technology (Zynth) provides a low-cost battery storage solution for the combined ESS, with the following characteristics:
The NPS-Eos ESS can be utilised for all the main commercial energy storage applications, such as:
