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?
It literally says in first paragraph “…in Sweden to deploy 211 MW / 211 MWh…”
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.
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.
