The CuBER project proposes the validation of a promising RFB technology, the all-copper redox flow battery (CuRFB), able to cover a wide range of the aforementioned market applications due to its simple, modular and scalable design, security and sustainability. Firstly, a 5kWDC CuRFB pilot will be designed for its integration in Smart Cities and residential self-consumption market segments within the CuBER action. Subsequently, the planning of further developments will allow its application at larger scales, both as back-up power system in isolated areas (i.e. copper mining) and for energy management and grid balancing in renewable power production. In this repository all public documents relating to the project and the type of battery will be shared
