> Build hydro-pump-storage plants, and you fixed the storage issues.

You do realize that the largest ever energy-generation accident was a dam failure? 171000 people killed in 1975 when a dam in China failed. And overall, hydroelectric facilities claim 94% of the fatalities of energy-production accidents.

What you are talking about is hydro-generation.

What I am talking about is hydro-pump-storage.

That type of storage has no dam that could fail – you take two lakes, one higher than the other, connect them with a tunnel, and place a turbine in the tunnel. Now you can push the water up (store energy) or let it flow down (produce energy).

Yes, that was a hydro-generation dam.

However, it is simply not true that hydro-pump storage never has a dam.

In fact, when you look at the list of pumped storage stations, the vast majority of them have dams:
