If sodium batteries are so much cheaper, why is the emphasis of this article on batteries for trucks and not grid-scale storage? Isn't the latter much more impactful?

Also naively I would expect sodium batteries to be heavier that lithium, which would make them worse for transportation but still fine for energy storage.

They haven't produced many yet. And when they do they'll probably sell them for applications where they can charge most and make profits. The Pioneer Na(sodium) portable power station thing in the article isn't cheap. The grid storage will come when production ramps up.
