This would be a lot more reassuring if the same (better storage in a bound form) hadn't been promised for at least 20 years, back then being solved in principle

  You would've said the very same about solar, wind, & grid-scale battery storage even 5-10 years ago. The commitment to scale is what made the "old" technology economically feasible. Incremental advances also played a role. This same equation is playing out for nuclear, Alane, and others. It's a matter of commitment & will -- both of which are gaining momentum.
