it’s a flow battery, so it keeps charge basically indefinitely (when not in use energy-bearing parts are separated). you can run it as hard as you need and it will not degrade in use-dependent way, at least not as hard as lead or lithium batteries
And how much would you have to pay people to take those thousands of Home Depot systems, string them all together, build a facility to hold all this, then hook it to the grid?
$1 per WH or almost that is pretty terrible. You can get battery systems for 1/4 of that $/WH at Home Depot.
Grid connected storage in the US goes for some 220 USD/kWh at scale. It’s some 100 USD/kWh in China.

People girls just use them in their homes and businesses.
And how long are those systems expected to last compared to those in the article?
When you build bigger stuff, costs per KWH are lower than you pay at Home Depot, higher.

Yeah, I agree that decentralization of the grid and self-consumption is better than these mass baseload solutions…but they will only get cheaper.
