Thanks for bringing those to my attention, that does sound like something that interests me. The "where can I buy" was notably absent from their website, but some further searching found a comment of someone who did find prices <https://pv-magazine-usa.com/2022/10/06/residential-flow-batteries-and-inverter-updates-from-the-floor-at-re/#comment-206125 https://pv-magazine-usa.com/2022/10/06/residential-flow-batt...> but it wasn't especially the price that made me pause as much as the assertion that the batteries have fluid pumps that must be kept running Since I apparently couldn't buy one then it doesn't matter but I would need to further understand what happens <s>if</s>when those pumps fail

They have a YouTube channel with some case studies and discussions[1] the channel intro shows high level what the battery chemistry and mechanism is - pumping electrolyte past a membrane and either dissolving or precipitating Zinc + Bromine to charge/discharge. They seem to be making a 10kWh cell which they can stack into a shipping container sized larger cell, and then deploy those to make grid-scale storage, rather than home use. Presumably they have an answer for if all the pumps in all those containers need regular maintenance, but I haven't thought about that until now. ('liquid tracks' should have been 'liquid tanks' in my earlier comment).
