> Storage in particular is so early in the cycle that we can expect the cost will drop at least in half. We've barely started making battery storage, the industry has 100x growth ahead.

You can add at least two more zeros there, and possibly three or more. Storage right now is mostly dams and all the easy places have been done. Battery storage is really at the proof of concept state and if you take hydro out of the equation you're looking at a tenth of a percent at best.

A continental-scale mix (wind, solar...) is an efficient way to reduce the impact of intermittency on electricity production, and therefore storage ( https://www.imperial.ac.uk/news/180592/european-cooperation-... ).

V2G ( https://en.wikipedia.org/wiki/Vehicle-to-grid ) and gas turbines burning green hydrogen (generated by water electrolysis using over-produced electricity) are ramping up.

There is a good chance that with present day technology we could satisfy all of our energy needs using HVDC transmission lines. The main problem is that these are going to be easy infrastructure to attack in case of war or through terrorism.
True, however continental-scale grids interconnecting more and more interdependent nations/states are needed whatever the type of energy source used (even nuclear), and at least as exposed to terrorism as long-haul (U)HVDC lines.
