Nijsse and colleagues find that due to technological trajectories set in motion by past policy, a global irreversible solar tipping point may have passed where solar energy gradually comes to dominate global electricity markets, without any further climate policies. Uncertainties arise, however, over grid stability in a renewables-dominated power system, the availability of sufficient finance in underdeveloped economies, the capacity of supply chains and political resistance from regions that lose employment.

    Most of that is fine during a dunkelflaute. The only really big issue is not having enough generating capacity, but even that likely works out. The most fuel generation during a single week last year was 24,302GWh so 144GW running throu. Sweden and Norway can generate 49GW in hydro at full power. Even the best weeks still have over 12TWh of fossil fuele generation in the EU, so that certainly goes a long way to solving the problem of dunkelflaute.

    But you are right, most of the year smaller storages to cover a night or so, is all you need. So you still want some TWh of battery and pumped hydro storage. That preserves hydro storage and is needed to balance the grid. Biomass is also worth a look for long term storage.
