These are the ones a in commercial production that will be shaking up the PS market.

Do the LCOS calcs for 50,000 cycles vs 3000 at $87 kWh cell costs....Yeah disruption level.
BYD uses CATL cells the largest manufacturer in the world by a huge margin.

Pretty solid econ analysis.
Then let’s not forget grid scale water and thermal tech is hot pun intended on the heels of power cells.

I have done SWD work with SAGE and this project. It easily scales to gigawatt hours there are over 100,000 wells in the Permian Basin any one of them could be retrofitted with SAGE tech.

MIT is.going the other way using liquid metals to store heat at high round trip eff which is irrelevant if you get electrons cheap enough throw half away if need be. It’s LCOS AND electron cost.

Gravel and Argon thermal should be super cheap as well.
Grid storage is here, the luddites will cry and moan. It really comes down to what can you buy electrons for and what can you sell them for later. Nothing more nothing less.
Solar and wind can produce sub $10 per MWh electrons this is fact today no literally today on a 80,000 megawatt sized market the sale price was $5 per megawatt hour from solar and wind this morning in real.time. Gas turbines cannot get to those levels of prices even with near zero as in $2 MMBTU fuel costs. So the age of power storage is here. Lots of money to be made in the field its what tech shakes out to have the lowest LCOS.
“So the age of power storage is here. “
In another post I pointed that out but not with the detail you presented.
This is one of my pet methods given my love for nuclear and being a PhD level Hydro Geo.
You can store thousands of gigawatts worth of energy in hydraulic fracture engineered storage systems aka EGS engineered geothermal systems. The heat doesn’t have to come from nukes any heat source that meets the delta T can be used, nukes just happen to be some of the cheapest source of heat humans have come up with. Joule heating either down bore or at the surface with electrons would work as well. Down bore joule heating would actually work better as there is no heat loss on the way down to the EGS. You don’t have to use water which tends to solution mine the surrounding rock strata CO2 is super critical at these temps and pressures its dense like a liquid but flows like a gas. So either nuke heat or surplus $10 or under per MWh electrons heats a enormous volume of rock that then spins turbines on demand for $$$$ more than the cost of the heat you put in. Chaaaching for the group doing the project.

The simple fact is once you have electrons under a cent per kWh lots of things start to make economic sense.
