Reply to comment by aurizon in US can reach 100% clean power by 2035, DOE finds, but tough reliability and land use questions lie ahead by nastratin
Tagging on here, molten salt batteries seem to be a good approach as well.

Yes, Several good methods are scaling up now, hard to say what type will win in the longer term. https://en.wikipedia.org/wiki/Molten-salt_battery

Thermal batteries will lose out to flow batteries or even old lead-acid batteries. Too many steps to charge/discharge such batteries, to many losses at each step. Thermodynamically, not the best strategy.

Sodium-sulfur batteries aren't thermal storage, they're just electrochemical batteries that need to be kept at high temperature (easy enough with a well-insulated tank, and it gets easier as you make them bigger).
