Title: Next generation redox flow batteries based on solid boosters for large-scale energy storage
Affiliation: Aalto University
Large-scale energy storage systems are urgently needed to manage intermittent energy production and improve the flexibility and security of grid systems. Redox flow batteries (RFBs) are an already established technology ideal for large-scale energy storage due to their high safety, long lifetimes, low environmental impact and decoupled power/capacity. However, the low energy density and high raw material cost of the state-of-the-art all-vanadium technology has proven to limit commercialization. During this presentation, ways to realize next generation flow battery systems for large-scale energy storage based on solid boosters and inexpensive redox active materials (such as inorganic metal complexes and organic species) will be discussed. Especially the concept of solid boosters, where “molecular wiring” to charge and discharge the redox active solid materials present as beads in a packed bed reactor will be discussed, and recent results from our lab will be presented.
