Thermal energy is the energy present in a system due to its temperature. Thermal energy storage (TES) is a technology that stores thermal energy for later use by heating or cooling a storage medium. This stored energy can be retrieved when needed for various applications. TES systems typically involve a storage medium, energy transfer mechanisms, and control systems. There are several types of TES methods: Sensible Heat Storage, Latent Heat Storage, and Thermochemical Storage. TES has diverse applications, including integrating renewable energy sources, optimizing HVAC systems, improving industrial processes, and enhancing district heating and cooling networks. Its importance lies in enhancing energy efficiency, reducing costs, stabilizing the grid, and mitigating environmental impacts. TES systems help reduce energy costs by utilizing cheaper off-peak electricity for storage and decreasing reliance on expensive peak-hour energy. Additionally, they promote grid stability by balancing energy supply and demand. Moreover, TES contributes to environmental sustainability by reducing greenhouse gas emissions. Ongoing research and development in TES aim to improve efficiency, reliability, and scalability. Innovations in materials and technologies are driving advancements in TES systems.
