Agreed all around, with one caveat.

On chemistry - Sodium Ion is a pretty solid bet for many reasons - material availability, energy density by weight, longevity (for some chemistries - others are only comparable to lithium), low-temperature operation for charge and discharge, cost, power (charge and discharge speed)… Also, it’s ecologically sound, in comparison with any other battery tech out there currently, and it’s at the beginning of it’s innovation arc. Also, it’s a tech heavily invested in by China, which has already spurred competition in other countries.

I’ll be attaching myself to that chemistry here in the next couple years to the tune of what I expect to be about ~$8k for about 50kwh of battery, as I’ll need a bank of them for my place soon that can handle quite a few days without sunlight while running a modest workshop and basic home needs. I might need to go larger than that, but… …energy storage isn’t cheap, and I can add to at at any time, unlike with lead acid storage.
