4. THERMAL STORAGE SYSTEMS

Thermal storage systems serve as an alternative to traditional battery systems by storing energy in the form of heat. These systems typically utilize materials like water or molten salts to capture thermal energy generated from renewable sources such as solar. The flexibility of thermal storage allows it to provide energy when sunlight is unavailable, making it a reliable option for renewable integration.

The two primary types of thermal storage are sensible heat storage and latent heat storage. Sensible heat storage involves storing thermal energy by changing the temperature of a substance, which is a straightforward and efficient method. In contrast, latent heat storage utilizes phase change materials that absorb or release energy during phase transitions, enabling higher energy storage densities. The choice between these two methods largely depends on application requirements, cost-effectiveness, and desired performance metrics.

Additionally, thermal storage can improve the efficiency of heating systems in buildings and industrial applications. By storing energy when demand is low and releasing it during peak times, thermal storage diminishes the need for fossil fuels, thus contributing to broader environmental goals. The integration of thermal storage strategies not only enhances overall energy efficiency but also bolsters grid resilience, particularly in regions with high renewable energy penetration.
