Renewable FlowStorage

The main objective of Renewable FlowStorage (RFS) is to develop and field-test a vanadium redox flow battery (VRFB) for storing electricity for domestic residential with PVs. It targets the development of a full prototype machine of 1 kW and 4 kWh storage capacity. VRFBs are very robust, flexible, environmentally safe and seen as the lowest price local stationary electricity storage technology that fits the needs of the private residential market. A VRFB is a reversible fuel cell where the redox pairs are dissolved in an aqueous phase and stored in separate tanks. One of the very attractive features of redox flow batteries are scalability between storage capacity and battery power.

The main objective of RFS is to develop a VRFB prototype with an attractive casing and user interface for domestic use. The first complete prototype will be ready for field-tests no later than 20 months after the beginning of the project
