It is possible that new battery chemistries or compressed air storage may prove cheap enough to use for long term storage.

There are plenty of options to choose from, but only few are actually industrial grade at the moment. So many promising ones are still in pilot stage, and I’m really looking forward to seeing which ones actually prove to be viable.

Traditional lithium based batteries clearly aren’t it, but LFP looks ok though.

The salt batteries will be even cheaper than lfp, they just take even more space, but we got lots of space to put batteries.

Exactly. Grid energy storage doesn’t have to be light or small. It’s not going anywhere, and you can build such facilities in remote locations.

Who cares if it weighs as much as a factory and takes the same space. You could go with molten calcium, redox flow batteries or even wilder technologies.
