Comment on Nuclear too slow to replace coal, and baseload “simply can’t compete” with wind and solar, AEMO boss says
Drill a hole and a deper hole and pump/turbine water between them
That’s really really expensive unless you already have natural upper and lower reservoirs.
It is? More than batteries? Im just suprised.
Based on some numbers I looked up a couple of years ago: LiPo 15¢/Wh Flywheel 15¢/Wh Compressed air 12¢/Wh Pumped hydro 11¢/Wh
I’ll try to dig up the sources when I get home, but the cost advantage isn’t too large.
Thanks! I guess the hydro is with natural reservoirs?
Just cause lithium ion is pretty subsidied and quite energy dense
No way. Far too expensive.
