3. EMERGING TECHNOLOGIES IN ENERGY STORAGE SYSTEMS

3.1. COMPRESSED AIR ENERGY STORAGE (CAES)

Compressed air energy storage systems utilize electricity to compress air, storing it in underground caverns or vessels until it is needed. Upon release, the compressed air drives a turbine, generating electricity. This method has the advantage of being able to store vast amounts of energy, making it particularly useful for grid management.

Though CAES systems are cost-effective for large-scale deployment, they require suitable geological formations for caverns. Moreover, efficiency improvements are underway, focusing on enhancing the energy return from compressed air systems. Such advancements could lead to broader applications and greater efficacy in future grid management.

3.2. THERMAL STORAGE

Thermal storage systems are gaining traction as a viable alternative for energy storage, primarily by leveraging heat energy. This technology involves storing thermal energy in materials, such as molten salts or ice, for later conversion into electricity or heating/cooling. Such methods provide a unique advantage as they directly respond to thermal energy demand cycles, complementing the energy grid in a manner akin to battery systems.

This approach offers additional versatility, especially in heating and cooling applications, which are often overlooked in traditional energy storage discussions. By shifting energy use, thermal storage solutions reduce stress on the grid during peak times while enhancing energy efficiency in various sectors.
