For large-scale energy storage, Na is attractive due to its global abundance and distribution, making it widely available. Commercially relevant Na batteries today can be roughly grouped into two primary classes: molten Na batteries and NaIBs.

They provide significantly more power in a smaller and lighter package compared to traditional lead-acid batteries. This compact design allows for efficient use of space in data centers and telecommunications systems, where rack space is often at a premium.

Vanadium redox flow batteries (VRFBs) are mature technology with long cycle lives due to using vanadium in both electrolytes. VRFBs are best for stationary energy storage applications, like grid-scale storage, microgrids, and backup power systems.
