Nuclear too slow to replace coal, and baseload “simply can’t compete” with wind and solar, AEMO boss says (reneweconomy.com.au)

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?

[–] JohnDClay 2 points 4 months ago

Yeah I think so

Just cause lithium ion is pretty subsidied and quite energy dense

No way. Far too expensive.
