@Ardubal @MattMastodon @BrianSmith950 @Pampa @AlexisFR @Wirrvogel @Sodis It is well worth reading the original Australian model.
That has 60% wind and 45% solar, with hours of storage, including some hydro, reaching 98%, using real world data (and scaling the output of existing plant). Going from 105% capacity to 170% eliminates the problem entirely - assuming no freak weather events not included in his ~ 1 year trace. Equally you could solve it with long-term storage. Long-term storage doesn’t have to be cheap or efficient per kWh; it’s the capital cost, the ecological cost (e.g. hydrogen leaks), and whether it’s feasible at all, that’s the real question.
If you don’t have nuclear equal to your *PEAK* demand, which looks unlikely on any reasonable timescale, then either you need quite a bit of storage, or you need to accept there will occasionally be power cuts for non-essential users.
@Ardubal @MattMastodon @BrianSmith950 @Pampa @AlexisFR @Wirrvogel @Sodis But the fundamental thing for me is I won’t wait for new nuclear.
We need to cut carbon emissions *NOW*. That might mean starting some new nuclear power projects. But both renewables and short term storage are being installed today, cheaply, and while there are some obstacles to this (e.g. grid access), balancing is not the main problem.
We can’t use nuclear as an excuse any more than we can carbon capture.

If you don’t have power output from storage equal to *PEAK* demand, it’s the same argument for any storage. And storage doesn’t /produce/ energy, it /consumes/ it (because of conversion losses, which are significant).
@Ardubal @MattMastodon @BrianSmith950 @Pampa @AlexisFR @Wirrvogel @Sodis Nuclear does not avoid the need for short-term storage to cover the peaks, unless you can build vast amounts of it (equal to peak).
Nuclear *does* avoid the need for long-term storage, if you can build enough of it (equal to average).
@matthewtoad43 @MattMastodon @BrianSmith950 @Pampa @AlexisFR @Wirrvogel @Sodis
You seem to argue that our /current/ fossil grid would also need more storage, but it works just fine as is. Nuclear is better at load following than fossils, so what gives?
