Generally refrigerators or hot water tanks aren’t considered batteries, but its true that electricity is not the only form of energy we use. It’s just the most easily distributed.
I’m surprised since they use so many machine tools, they don’t have a compressed air system. That can also be a form of energy storage. There’s already a bunch of machine tools that run exclusively on compressed air.

There are a few articles that had been devoted to discussing compressed air systems for energy storage. It is what got me to learn about the system.
