Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

Scientists have been looking for solutions in gravity energy storage , thermal or geothermal storage , and also molten-salt batteries. A recent study from the Pacific Northwest National Laboratory (PNNL) looks at molten-salt batteries that can “freeze” their charge for months until required.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

Energy storage has two main factors—how fast it can be charged and discharged (the spigot) and how much total energy it can hold (the bathtub). The bathtub is cheap for us, so when it comes to how much we can store, we can increase that capacity quite cheaply,” says Michael Simpson , the cofounder of Cheesecake Energy.
