Reply to comment by drgrieve in Italian startup Energy Dome claims its CO2 grid storage batteries are cheaper than lithium-ion, and need no rare minerals, being made from just off-the-shelf steel components, water & CO2. It's opening its first 200 MWh facility in Sardinia in 2023 by lughnasadh

Wait they pay you to waste electricity in Australia sometimes?

Yes. The coal plants fight wind and solar for the right to not turn off and make it up for when the sun goes down. However they can't pay rooftop to turn off, so they are month by month losing the war. In Aus we install 200MW every month of rooftop. If everyone had rooftop as cheap as us they could do the same.
