"The system combines a 2MW/5MWh vanadium flow battery from Invinity Energy Systems with a 50MW/50MWh lithium-ion battery from global technology company Wärtsilä to deliver an innovative energy storage solution that can balance the intermittency of renewable energy."

What I find interesting, is that VRFB dont have to completely replace Lithium-ion batteries, but seem to be a good addition to lithium-ion based grid storage. So, there's room for both, and more Li-ion batteries could mean more VRFBs at the same time.
