They won't use batteries for grid scale storage, that's a bit too expensive. They'll probably use hydro, some sort of heated mass or compressed air. Or gas, it's much better than coal at least.
- ZeroGravitas 4y agoI think in this model it is actually batteries. They pair pretty economically with solar to smooth output on the daily cycle. They also include existing Hydro in their model, plus 'other' which is what mostly covers the storage on longer scales. But there's easy answers for the rest too. It's just not modelled in this very simple model because most of the heavy lifting is always going to be solar and wind and that's probably the point they're trying to make.
- plantain 4y agoI think Australia will use mostly batteries, but we are building more hydro. I think hydro is miscast as being green though, when in reality it causes enormous ecological destruction. Hydro is also intermittent - it requires the right amount of rainfall, currently hydro in Australia is not able to reach full generation because it will flood downstream as it's been a wet year. Hydro is not that cheap (depending on the metric you need) - see an example[1] comparing Australian hydro to the aforementioned Victorian Big Battery.
