Very insightful. At grid scale the line between them just blurs because of how they're ultimately used. But there are some differences and ultimately a grid scale pack would be both packed in one. With caps taking the blows to smooth into the chemical storage of the battery behind it or head right back out before a need to store in the chemical behind the cap.

No_Maines_Land@lemmy.ca 2 weeks agoI would think capacitors would be better than batteries are grid scale? Particularly for the buffering you mention.

Capacitors don’t hold energy for long.

They’re essentially the same thing on the scale of a national grid. Battery banks can turn on the juice in microseconds.

grid buffering does not need that. It’s literally guys looking at demand and phoning around to turn up or down generation.
Fun fact: this was the first in a series of events that caused the Chernobyl explosion.

Oh yeah, it’s massive overkill for the conventional grid. It’s just one of the things I see people say when trying to get people to accept that battery banks can make a renewable-only grid viable here in Australia.
