Reducing greenhouse gas emissions by 80-95% in 2050, compared to 1990, as worldwide agreed upon, can only be done by large scale deployment of renewable energy sources. To integrate renewable energy derived from intermittent sources, such as wind and solar, into electrical power grids, large-scale electrical energy storage (EES) systems are needed to improve reliability. A promising EES technology are redox-flow batteries (RFB), but current RFBs rely on redox couples that are non-indigenous to Europe, and costly. The HIGREEW project focuses on the development and validation of a sound Aqueous Organic Redox Flow Battery (AORFB).
