As per Market Research Future, Molten Salt Energy Storage Systems are gaining significant traction due to their efficiency in storing high-temperature thermal energy. These systems are widely used in concentrated solar power plants to store solar heat for electricity generation after sunset.
Molten salt mixtures, typically composed of sodium and potassium nitrates, can retain heat at temperatures exceeding 500°C. This high-temperature capability allows for efficient steam generation and continuous power production. The technology offers long-duration storage, making it ideal for utility-scale applications.
One of the main advantages of molten salt systems is their cost-effectiveness compared to battery storage for large-scale thermal applications. They also offer longer operational life and lower degradation rates.
Global investments in renewable infrastructure are boosting demand for molten salt storage. Governments are supporting CSP projects to diversify renewable portfolios and enhance grid reliability. Additionally, research efforts are focused on improving salt formulations and corrosion resistance to extend system lifespan.
However, challenges such as material corrosion and high initial capital expenditure persist. Despite this, technological advancements and economies of scale are reducing costs and improving performance.
Molten salt energy storage systems are expected to remain a cornerstone of large-scale renewable energy projects, contributing significantly to global decarbonization efforts.
