@sbi excellent thread, very eye opening. what about physical energy storage, like pumped hydro, gravity batteries or spinning flyweels?

@mdione The first two are about tertiary control, flywheels are about primary control. So far, I have not yet come into contact with any of those. The main objective of this thread was to explain that batteries, while problematic for large-scale storage due to their low energy density, still play a key role in the transition to renewables because they can replace fossil fuel generators for primary control, and that they can do this *now*, and at a profit.
