More importantly time shifting that daytime solar is a huge problem and you can’t handwave it away; this article is talking about how we’ve grossly underestimated the amount of resources needed for vehicle EV while grid batteries would shift that even more. We might get lucky with a totally new battery chemistry, but battery chemistry moves relatively slowly.
