  The important bit is that sodium is much cheaper than lithium, and that translates into the batteries being less expensive per watt-hour. They're larger and heavier for the same capacity, but the lower price makes up for it, especially in grid-scale storage (where size/weight is nearly irrelevant).

    Isn't sodium also heavier?

      > They're larger and heavier for the same capacity, but the lower price makes up for it So yes, the battery will be heavier because sodium's heavier, but it's so much cheaper that you can afford the extra footprint.
