Molten Salt Energy Storage+

Molten Salt Energy Storage+

With heat storage technology at its core, we focus on integrated energy supply applications and provide customers with comprehensive zero-carbon energy solutions.

Principle Introduction

Molten salt energy storage utilizes the liquid properties of molten salt at medium and high temperatures. The temperature difference during the heating and cooling of molten salt is used to store and release thermal energy. Specifically, a molten salt energy storage system typically includes components such as molten salt storage tanks, heaters, heat exchangers, and power generation equipment. During the energy storage phase, molten salt is heated to a high-temperature state (usually between 200°C and 600°C), storing a large amount of thermal energy. During the energy release phase, the high-temperature molten salt transfers heat to the working fluid (such as water or steam) through the heat exchanger. The heated working fluid drives the turbine to generate electricity, converting thermal energy into electrical energy.
