Grid Connected Flow Batteries

The main objectives of Grid Connected Flow Batteries (GCFB) are to configure and field-test Vanadium Redox Flow Batteries (VRFB) for how this specific battery technology can add flexibility in the low-voltage grid; in the future grid we expect more PV installations at private houses and companies, which may cause temporary local imbalances in respective feeder lines. VRFBs are very robust, flexible, environmentally safe and seen as the lowest price local stationary electricity storage technology that fits the needs of ancillary services in the low-voltage grid to the Distribution Service Operator (DSO). One of the very attractive features of redux flow batteries are scalability between storage capacity and battery power.

The technology creates the opportunity for the grid owner in an agile and flexible process to dimension the technology in steps as they learn the demand from the specific feeder lines.
