We have those, that’s pretty much how big energy plants work (Coal, gas and fusion all use that I think), it’s not exactly a flywheel, but a large turbine which can keep spinning for some time. I think a full on flywheel would have to be absolutely massive to produce enough energy to be meaningful, which is probably just not worth it
