Phase Change Materials (PCMs)
Phase Change Materials (PCMs) are substances that can store and release large amounts of thermal energy during the process of melting and solidifying. They are being used in various applications such as building cooling and heating, solar energy storage, and thermal management of electronics.
Thermochemical Energy Storage (TCES)
Thermochemical Energy Storage (TCES) involves the use of reversible chemical reactions to store and release thermal energy. This technology has the potential to offer high energy density and long-term storage capabilities, making it suitable for grid-scale energy storage applications.
Underground Thermal Energy Storage (UTES)
Underground Thermal Energy Storage (UTES) systems utilize the subsurface to store excess thermal energy, which can be retrieved when needed. These systems are gaining popularity in district heating and cooling, as well as in industrial processes, due to their high efficiency and minimal environmental impact.
Molten Salt Thermal Energy Storage
Molten Salt Thermal Energy Storage systems use molten salts as the heat transfer fluid and storage medium. These systems are widely used in concentrating solar power plants to provide reliable and dispatchable energy supply, even when the sun is not shining.
Cryogenic Energy Storage
Cryogenic Energy Storage involves the liquefaction of air or other gases to store thermal energy at very low temperatures. This technology is gaining attention for its potential to provide long-duration energy storage and support renewable energy integration in the power grid.
