TLDR connecting far-flung regions into one huge grid can mitigate the intermittency of renewables. High-voltage direct current is a good way to do this.

Is this really more efficient than, say, building a big plant that does electrolysers or a bunch of giant flywheels to store excess energy? Or simply optimizing time-of-use to correspond when productivity is highest?

electrolyzers consume about 44kwh per kg H2 generated, and solar ain't efficient either:200w capacity per m²..
