Jern Flow Batterier til Maritim og Stationære Applikationer

The project aims to develop an innovative energy storage solution based on iron-flow technology that can provide reliable long-duration energy to marine vessels and to grid using non-toxic, environmentally friendly, cost-effective, and non-flammable iron-based electrolytes. Innovation in the use of water soluble coordination complexes of iron will allow operation at circumneutral pH. This will represent a large non-iterative step that will circumvent energy losses and the need to re-balancing cells as a consequence of plating and H2 evolution processes. Advantageously, this will simplify significantly stack construction.

The partners will follow an application-oriented approach for a fast-track development towards TRL4-5 for the system. In addition to “all-iron all-soluble” new generation iron flow batteries (Gen 2), incremental improvement in the state-of-art all-iron flow battery (Gen 1.1) will be investigated. A detailed testing campaign will be performed on a large-scale commercially available iron-flow battery (75 kW / 500 kWh) to achieve a deep understanding of the system and improve upon the battery operation. A control strategy will be designed for the overall system to optimise operational efficiency and stability.

Finally, attained innovation in cell design and chemistry will be demonstrated through construction of a prototype power stack. KPI’s of the assembled stack will be validated against the calculated design values.
