TFA, and other articles I can find about Heron's Nest install, just refer to a 'battery' (255kWh) but don't mention type. So I'm assuming it's a Li-ion variant.
But with several dozen home's worth, it feels like it'd be close to where the cost / scaling of a flow storage system would be much more compelling over a conventional Lithium system.
(I'm grid-connected, with solar, eyeing off storage systems, but here in AU our prices are high and our options are small. Flow storage looks to be an objectively superior design, but at single-dwelling scale the pricing is just not competitive, at least not yet, and not here.)
