The author appear to be accepting AGW as established fact and that debate is needed as how to handle it.

In reality debate is needed to prove whether or not thermal properties of ocean algae plant matter mass could be sometimes linked to warmer areas of ocean.

Someone long way back said;
It's ironic that Holden is closing just weeks before SA is supposed to
get the world's largest battery

Well the battery would not be much use, it would keep Sth Aus going for
9 to 15 seconds depending on time of day.
They have never said what its purpose is but I suspect to enable a black start.

Baźz.

I think S.A's biggest in the world electrical storage 'battery' involves using daytime solar energy to pump sea water up into a mountain reservoir and then run that water back downhill at night though turbines to generate power.

JF Aus, I don't see how the battery would fit into such a scheme.
If you have the spare solar/wind output you just use it direct to
push the water up the top.
When you need the extra supply you run it down then.
That way you avoid the battery losses. The battery would be redundant.
Anyway has SA got the up mountain storage of suitable size ?

Bazz,

I suggest think SA's giant battery like this.
Think beyond chemistry of present day batteries.
Water is a chemical.
They could be proposing to cycle the water up into an earth reservoir and at night pipe it down down using gravity to turn turbines.

Likely it's a world first type of battery.
Not many countries would have excess wind and sunlight to pump enough water up, to charge the system.
Water and mountains are also needed.

Anyway I think there would be ecological problems putting salty sea water on top of the fresh water - water table.

JF Aus, no, they would line the "Turkey Nests", as they call them,
with plastic.
They are talking about a real battery of 100 KWHr rating probably
lithium considering who will be supplying it.
Tesla is in the business of supplying large battery installations.
They would be great for keeping large computer systems operating in
a blackout, or to supply a hospital.
However I suspect cost is the reason you see No-Break diesel systems
installed in hospitals etc as a tank of diesel could keep them
operating (no pun intended) for a week or two.
