This is very neat. I wonder what the energy loss is, between what's required to lift the water and what's gained by releasing it. Regardless, eco-friendly high density "batteries" are a great concept.
If you have the system always running most of the cartage back to the top could be handled by the siphoning effect, like draining a washing machine or siphoning patrol.
You'd need energy to get it started but after that it should keep siphoning as long as there's liquid to siphon.
I don't understand how that would work in this case; if this is true, I think I'd need to see a diagram.
My understanding is that they use energy to pump the liquid up during times of excess, and release it to generate energy when there's more demand.
