The research and development is ongoing, and anyone who discounts it is simply pissing over the wrong side of the boat...You're right about non-lithium batteries. Flow battery technology is advancing steadily but still barely viable in domestic situations, unless reticulation is expensive due to remote sites.
The prices of PV and battery storage is dropping fast which is seeing its economic viability improving vastly. Our last 5kW PV installation cost us close to $31K 10 years back, which we recouped with the sale price of that property, whereas our current 5kW installation was less than half that price with far better generation utilisation due to the improved technology included in it.
