Batteries are the wrong tool for that, storing large amounts of energy is the domain of pumped hydro.

- sofixa 2y agoPumped hydro requires specific geography (lots of water, high and low points) and significant earthworks around it, which makes it unviable in a lot of places.
- eigenspace 2y agoWhile pumped hydro will definitely play a role in seasonal storage, I doubt it's going to be the main solution. IMO, hydrogen and biogas are going to be playing dominant large roles in seasonal storage once the grids becomes so renewable-heavy that normal daily operation during normal weather can be covered by wind and solar.
- lrem 2y agoPumped hydro is a bit problematic when all you have are tiny hills that freeze over.
- Retric 2y agoWhen you’re talking even 3+m deep bodies of water they don’t freeze solid even in the arctic circle. A thick layer of ice on top still provides the same weight, so winter just doesn’t change anything. There’s some countries where the geography doesn’t work out, but most midsized countries already depend on exchanging power with their neighbors simply on economic grounds.
