Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

Especially for sources like wind and solar, which have discontinuous availability. While rechargeable batteries are the solution of choice for consumer-level use, they are impractical for grid-scale consideration. However, in the PNNL team’s demonstration, the freeze–thaw mechanism of the molten salt is able to circumvent that problem.
