Many of these are largely theoretical, or for temporary storage. For instance, I don't think fluwheels can store energy for months.

Are you proposing that the sun may not shine and the wind not blow anywhere at all for months?

[–] someacnt_@lemmy.world 4 points 4 months ago

Yeah, it is like that in some places. Also solar flux vary a lot by seasons as well. Dunno if wind has as much of an issue, but surely not great.

Nobody wants energy stored for months. Whatever storage is used needs to get through temporary decreases in efficiency. In places that use solar, that means from one afternoon to the next morning. In places that use wind, it means until the wind picks up. We're talking storage on the order of tens of hours at the most.
