Unfortunately we have many many dams/reservoirs in poor condition in this country along with other aging infrastructure IE roads and out power distribution network.

Big dirt work projects are extremely expensive so they tend to wait till it fails or almost fails before fixing it... Heavy equipment operating costs and the massive cost of the environmental paper work are a killer. Few realize how much of the cost of construction these days is the environmental impact study alone.

Here is another article on gravity storage. It goes over the few companies working on it. Interesting ideas!

That one has already been through the debunking ringer. It's another solar road scam. The science is clear it isn't feasible. It works but the return is so low making it extremely inefficient and it can't be made better.

Pumped Hydro is the only thing that works but building them is extremely costly and there are few places that they can be done and when it can the environmentalists make it nearly impossible to build unless they get their payoff.

Yeah, saw this a few years ago. Neat concept but my initial thought is that there's no way this can output enough energy to really be worth it.

The same power to weight ratio numbers apply to wave power.
Sailing our yacht at night with only the stars and compass to entertain one, used to wonder about using wave power to generate electricity, and as an even more direct use, to operate the pumps for desalination of sea water. In those day I could do the calcs in my head, not so much any more.
A seven ton yacht, up and down a wave X ft high every Y seconds.
If is pretty tough to beat batteries for economy as battery prices fall each year.
