From Lab to Grid Application: Development of a 5 kW/12 kWh Aqueous Organic Flow Battery in project HIGREEW

The aim of project HIGREEW was to develop a novel type of flow battery system with aqueous organic electrolytes using a European supply chain in order to minimise material dependency and increase sustainability. In this work we present the final steps of the project, the construction and commissioning of a kW-scale aqueous organic redox flow battery (AORFB) prototype and its implementation in the real environment at "La Plana Hybrid Pilot Plant" near Zaragoza, Spain
