US firm Eos Energy Storage has signed two deals in as many weeks as it looks market its aqueous, zinc hybrid technology for off-grid and grid-connected applications.
Both partnerships with make use of Eos’ Aurora® DC battery system that uses its patented Zynth (zinc hybrid cathode) technology.
The Eos Aurora battery system costs $160/kWh for the DC system and can reach 5,000 full depth-of-discharge cycles, say the company.
The system comes in 250kW/1MWh, but is scalability is only limited to the project’s available footprint.
The first partnership will see Eos’ technology paired with Northern Power’s FlexPhaseTM energy storage inverter, controls, and engineering expertise.
The integrated ESS will be targeted at utilities, commercial and industrial applications.
Eos and Northern Power began the partnership in 2016 and plan to deliver fully-integrated products to major utilities in the second quarter of 2017.
The second partnership will see Eos working alongside Siemens Corporation, a subsidiary of German firm Siemens AG.
Eos and Siemens have jointly developed ESSs that includes AC power conversion and controls to enables cheaper system upgrades.
Charles Russell’s, Business Development Manager at Eos’ told BBB: “Eos provides the full DC system including the outdoor rated enclosure and battery management system.
“The remaining pieces will be provided by Siemens. This will include the inverter, intelligent controls, and EPC work.
“Every project is slightly different with respect to the balance of plant required. As such, the Siemens scope of work, and product provided, may look slightly different for varying projects.
“The degree to which you can scale up from there is only constraint by land and the project economics. We expect much of our business to be project sizes north of 10MW|40MW/h.”
