Plus Power’s Kapolei battery is officially online. The pioneering project is a leading example of how to shift crucial grid functions from fossil-fueled plants to clean energy.

There’s some promising headway with molten sodium-sulfur batteries. Not only are they at similar capacity as lithium, but their molten nature allows for the batteries to store energy long-term. The downside is a low cycle rate and the heating requirement. Another promising battery tech is sodium ion batteries, which can use iron as a cathode to output similar power and cycling as lithium

This application needs the opposite of that. They need lots and lots of cycles, easy to maintain, and density is not much of an issue.
Sodium-sulfur batteries are designed for the role of grid storage.
