Can you offer an update on this system? I went to the companies site and there was not anything recent.

“The storage capacity of a 7 acre site could amount to more than 2 GW (2,000 MW)”
Is this meant to be 2GWh?

Scarcity of fresh water in a system like this is not an issue since it is a closed loop. Buy using fresh/distilled water over salt prevents corrosion and chelation issues.

I came up with this exact idea, except mine was not underground.

This is a closed loop system, it it not?

Water squeezed out the bottom during recovery will be fed back on top of the ‘plug’, thus increasing the weight on the remaining water?

Fill it up once, check the levels from time to time. Water shouldn’t be a constraint.

Yeah, like for solar thermal, it will probably have to use brackish water or
used industrial water (maybe from nuclear plants?) to get permits.

How about using salt water? (then that leaves the more scarce fresh water out of it). plenty of salt water, right?

We may know more about that bladder idea in May.

Or, just a bladder?

For “offshore,” just sink a tank (with plunger, return, etc.)

That would work, right?
