Certainly interesting. The Ashlawn Energy battery is also vanadium redox based, so the potential to extend the discharge cycle from 4MWh to 8MWh and beyond (assuming that is one of several objectives in the appointment) would be a substantial achievement IMO in itself, and help to affirm the beneficial advantages of VRF over other battery types.
Batteries are not just about power stored. The key is also in discharge cycles, their complementarity with renewables, and their suitability to providing resilience to our modern electrified world.
