Molten Salt Battery Market Size, Share & Industry Analysis, By Battery Type ( Liquid Metal, Sodium-Sulphur, Others ), By End-Use ( Military, Power Plants, Electric Vehicles, Others ) and regional Forecast, 2024-2032

Energy storage is an important tool to enable and unlock the benefits of the effective integration of the renewable power generated in the given area. The players involved in the energy storage market are focused on developing advanced energy storage systems, which are mainly for the developed economies. The molten salt battery is a type of battery system that uses molten salts as electrolytes and provides high power and high energy density. Molten salt batteries store the energy from the solar and wind power plants to supply it to the grids. The molten salt battery system operation is carried out at an elevated temperature, and the temperature is maintained by self-heating during the charging and discharging of the battery.

By battery type, the molten salt battery market is classified as the liquid metal battery, sodium sulphur battery, and sodium-nickel chloride battery, among others. In the liquid metal battery, the electrodes and the electrolyte are in the liquid state, and the battery is used in the grid-scale electricity storage. The sodium sulphur battery consists of sulphur and sodium electrodes with an electrolyte between them. The sodium sulphur battery has applications in renewable energy storage. By end-use, the molten salt battery has energy storage and supply applications in military, power plants, and electric vehicles, among others.

Lithium-ion batteries have been used in energy storage applications in renewable energy plants. However, the manufacturers in the energy storage market are focused on developing new batteries, which would be more cost-effective and efficient as compared to lithium-ion batteries. Molten salt batteries being one of them, are in the introduction phase in the market and have applications in the energy storage systems for renewable grids. Owing to an economical cost and high efficiency over the conventional counterparts, the molten salt battery market is expected to witness robust growth in the coming years. The molten salt batteries have applications in electric vehicles, and the growth in the sales of electric vehicles is expected to drive the sales of molten storage batteries in the near future.

The molten storage batteries are manufactured by a handful of manufacturers in the market. Owing to this, the molten salt batteries are not available in all locations and hence lead to growth at relatively slower rates.

Key Market Driver -

Economical costs of batteries as compared to those of other counterparts 

Key Market Restraint -

Low penetration of the molten salt battery in the market owing to a few manufacturers present across the globe
