The HIGREEW project started on 1 November 2019 and will run for 4 years.
The project is funded by the European Commission in the Research and Innovation Action Programme.
10 Organisations from 5 different countries work together to to design, develop and validate an advanced redox flow battery, based on new water-soluble low-cost organic electrolyte compatible with optimized low resistance membrane and fast electrodes kinetics for a high energy density and long-life service.


  1. To develop and optimize the aqueous organic electrolyte-membrane-electrode tandem;
  2. To design, build, test and validate efficient AORFB cells and stacks;
  3. HIGREEW prototype engineering and validation in pilot facilities;
  4. Demonstrate the use of AORFB through the integration with renewable energy sources;
  5. Ensure safety and sustainability of the HIGREEW technology.
