I found THIS interesting. They use excess wind energy to pump water up a mountain into a reservoir. Then they release the water into a hydrogeneration system when wind and solar is low. Of course this only works at a small scale in certain locations, but it's one way to store wind or solar energy.
Old news. There's a big one on Lake Michigan that's several decades old.
The problem is there are limited locations where it makes sense. Electric storage is still a huge issue.
Europe has been pump water back up mountains for decades, it is done at night when power demand is lower. My father saw it in the early 1950's. At Grand Coulee Dam in Eastern Washington some of the water pumped up and stored in Banks Lake can be used a second time to create electricity. The rest is used for irrigation of crops.
