RE:Alternatives ready to come out.
As a matter of factt VRFBs have nothing to offer in this league. The electrolyte that would be necessary to support projects of this size just doesn't exist and cannot be produced in the foreseeable future. LCE stated it would take them a couple of months to produce the electrolyte needed for the tiny 6MWh Mallorca battery. The same applies for Bushveld's Belco who are still struggling to get the plant built.
