This looks exactly like I always imagined battery storage should look like, at least in a first step. Mid-sized batteries strategically distributed in the grid for frequency regulation/grid balancing.

I hate mixing W with Wh.

Is it 211 MWh battery storage with maximum power output (peak, average, etc.) of 211 MW?

[–] [email protected] 5 points 3 weeks ago

It very much looks like it is 211MW lasting for 1h giving 211MWh.

It literally says in first paragraph "...in Sweden to deploy 211 MW / 211 MWh..."

= 1 h

It's not a strictly technical megazine. That's why I have doubts.

[–] [email protected] 2 points 3 weeks ago

Ha, right. Seems that distinguishing between power and energy is really a hard task (for journalists).

= 1 h

MW / MWh = 1 h^-1^, no?

There is usually a 1:1 between MW:MWh at these capacities.

Sadly no info whatsoever on batteries.

I found this on it; still need to read through it. Some sort of lithium battery technology, it seems.

[–] [email protected] 4 points 3 weeks ago

I don't know specifics on this battery farm, but almost all are essentially fleets of shipping containers filled with smaller batteries, rather than some super-cool-mega-battery, so it's probably a safe assumption that this is a landmark project in scale, rather than in technology specifics.

Li-Ion seems to be the go-to solution. I hope new static energy storage projects will prefer other options (Na-Ion, flow batteries, ..) since there's a limited supply of Lithium and we need it for vehicles.

[–] [email protected] 3 points 3 weeks ago

Yeah, I was hoping for other less toxic and more nature friendly ones, too.

It's the only chemistry possible to source unfortunately. I read about other chemistries, but they are hard to find.
