The adaptability of CAES systems allows them to be paired with various renewable generation sources, making them highly versatile in addressing the challenges associated with modern electricity demands.

5. THERMAL ENERGY STORAGE

Thermal energy storage (TES) systems present another realm of opportunity in the energy storage landscape. By storing energy in the form of heat, these systems can effectively manage energy supply and demand. The two primary forms of thermal storage are sensible heat storage and latent heat storage. Sensible heat storage involves heating or cooling a medium, while latent heat storage stores energy by changing the phase of a material, such as melting ice or fusing salt.

A remarkable aspect of TES is its applicability across numerous sectors, including district heating and cooling, industrial processes, and concentrated solar power (CSP) plants. For instance, CSP plants utilize TES to store excess solar energy during the day and generate electricity even during night hours. This capability is a game-changer in areas where energy generation must dovetail with peak consumption periods.

While TES presents compelling advantages, it must also be considered within the broader context of energy efficiency and cost-effectiveness. Effective integration of TES systems into existing infrastructure can maximize energy savings and reduce reliance on fossil fuels, thus contributing positively to long-term carbon neutrality goals. It signifies the growing trend of combining various storage technologies to create a more resilient energy mix.
