200MWh is about 1/100 of Little Boy, the atomic bomb dropped on Hiroshima. Compressed air can get out all at once given the right circumstances. Storing energy in a way that can go boom is something I'd be a little scared of, were I a nearby resident. I'm sure thermal batteries can have gnarly failure mechanisms but I would way rather live near one of those than a giant compressed air cylinder.
