The head of the Australian energy market operator AEMO, Daniel Westerman, has rejected nuclear power as a way to replace Australia’s ageing coal-fired power stations, arguing that it is too slow and too expensive. In addition, baseload power sources are not competitive in a grid dominated by wind and solar energy anyway.
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 surprised.
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, so digging your own reservoirs would put it as more expensive.
Thanks! I guess the hydro is with natural reservoirs?
Yeah I think so
Just cause lithium ion is pretty subsidied and quite energy dense
No way. Far too expensive.
