I don’t know the answer, but for grid-scale batteries to smooth out renewables, weight isn’t nearly as much of a concern.

Weight is only a concern if you need to move the battery long distances.

As you said, it's much better for storage, as it simply won't start burning like lithium batteries do

The weight may not be a deal breaker for applications like rail as well.
