Flywheels are a pretty good solution for ride-through of brownouts. Fairly compact and instantly available.

Where are they deployed at scale?

Literally everywhere. They're standard issue.

The Level3 building in San Diego had a two story iron flywheel that got loose and cut its way through the highway.

They are by far the most common kind of energy storage on Earth. Even in your car, which has both.

Hospitals, datacenters. Plenty of them to ensure that operation theater gear continues to work uninterrupted in case of brown out or the - short - interval during which generators start up if the power should fail.

Teraloop, AFS and others.
