I can dismiss the the other solutions that are worse then pumped hydro because pumped hydro is actually the best case scenario for grid-level storage and it requires A LOT of space. Anything else, batteries, pneumatic mines etc etc are going to be worse in terms of space by orders of magnitude, not to mention the actual costs. Hand waving the need for grid-level storage by saying we would us hydro shows you don’t understand the scale of the problem.

That excerpt from that engineer is great, but WHERE IS THE STORAGE? Show it to me on a map. You can’t because it does not exist. New Nuclear plants are being built, finally, but there is a reason that no grid-level storage exists. It’s literally not possible today. There exists a pilot battery plant in Australia, and there exists a few megawatts of storage in Scotland, but these are few and far between and none of them are suitable for massive deployment.
