Types of Thermal Energy Storage Systems in London
Underground Thermal Energy Storage
Underground thermal energy storage (UTES) is a system that uses the ground as a reservoir for storing thermal energy. In London, UTES systems are becoming increasingly popular due to their efficiency and ability to utilize geothermal energy. This type of system consists of pipes buried underground, which are used to circulate a heat transfer fluid. During the day, excess heat is stored in the ground, and during the night, the stored heat is extracted to provide heat energy for various applications such as heating buildings or water.
Ice Storage
Ice storage systems are another type of thermal energy storage technology used in London. These systems use the process of freezing water to store thermal energy. During off-peak hours, when electricity costs are lower, water is frozen to form ice. This ice is then used to cool buildings during peak demand periods. Ice storage systems are particularly suitable for applications where cooling is required, such as air conditioning in commercial buildings.
Hot Water Storage
Hot water storage systems involve storing thermal energy in the form of heated water. In London, these systems are commonly used for heating purposes in residential and commercial buildings. During periods of excess energy, hot water is stored in insulated tanks. This stored energy is then utilized during peak times, reducing the dependency on conventional heating systems. Hot water storage systems are known for their reliability and flexibility in providing heat energy.
Phase Change Material Storage
Phase change material (PCM) storage systems are an innovative solution for thermal energy storage in London. PCM is a material that can absorb and release large amounts of thermal energy when it undergoes a phase change, such as from solid to liquid or vice versa. PCM storage systems can store thermal energy at a specific temperature and release it when needed. This technology is especially useful in applications where precise temperature control is required, such as in industrial processes or heating and cooling systems.
