When size and weight don't matter, lots of other battery chemistries can work.

    Batteries are the bottleneck now that solar PV equipment is so cheap. I’m excited to see how ot plays out.

    The more that aren’t lithium, the better. Lithium is about as good as we can get currently in respect to energy density and weight. Neither of these things matter for grid-scale, where service life, safety, and environmental cost should be much more of a priority

      All of which the new sodium batteries solve. Massively improved cycle life, completely safe, and the environmental cost is a tiny fraction of what it is with lithium-based.

      I don’t get why there aren’t 50 companies rushing to produce it at-scale for in-place batteries. They should be chomping at the bit trying to get government contracts to install massive battery parks.

      Maybe it is just too new that they want to see how the small batteries do in the field.
