Actually, when reading the ad at the end of the article ("The 30% federal solar tax credit is ending this year. If you’ve ever considered going solar, now’s the time to act.") I was surprised that Trump didn't cancel this retroactively, as he did with lots of other measures decided by the Biden administration...

The price of the battery (compared to the price of Lithium) is not mention, nor is relative size (and weight). However, once in production it's expected to be cheaper to produce, albeit requiring more space / weight per Kwh.
So it may not replace car batteries, but for residential or grid-based solutions it should move the needle. Personally I'd love a cheap 100Kwh battery at home, and I don't care about size or weight...

With or without import tariffs ?
If import tariffs can shift the price in favor of sodium-ion batteries that would be a great win, as sodium-ion batteries are much greener (extracting lithium is a very environment-damaging process) and free of slave labor (to extract rare earth materials like lithium).
