Thing is, other than mass produced unit technology like li-po and li-ion cells, there’s precious little available storage. I tried to get quotes from a company that sells liquid flow redox batteries, the sort of technology that should scale volumetrically but it’s just not feasible for anyone to deliver beyond small deployments. We can’t order X-kWh storage off the shelves with anything but lithium batteries at the moment and until we can, there will be serious questions asked by people…even enthusiastic people like myself, because I look at the daily cycle count and go “fuck off” I’m not replacing 25% of a lithium battery tech based energy storage every 3 years, grid scale facilities are designed around 25 year cycles and anything with less than a 10 year lifetime feels like flushing money down the drain on razor thin margins, both economically and environmentally once you account for the manufacturing costs of the lithium based energy storage equipment.
