I don't really know a lot about energy. Is this similar to something like Energy Vault[0] or is stabilizing the frequency different to storing power for later use.
This energy vault device will not work for a couple of reasons.
Like the astonishingly low energy density of such a structure or the difficulty in running and maintaining the cranes to pull the weights. It is basically a mechanical version of pumped hydroelectric energy storage; just clunky and inefficient.
Flywheels store orders of magnitude more power per ton and have very low reaction times (in the order of milliseconds).
This makes them great for frequency control which just means really short term energy storage.
The power grids frequency is directly co-related with the power throughput. If there is too much demand the frequency will drop.
A flywheel can quite easily buffer very short term demands and flatten the somewhat erratic output of wind turbines or solar.
