Long-term storage of the energy they generate is another matter. The solar energy system created at Chalmers back in 2017 is known as ‘MOST’, meaning Molecular Solar Thermal Energy Storage Systems. The technology is based on a specially designed molecule of carbon, hydrogen and nitrogen that changes shape when it comes into contact with sunlight.
Thermal storage materials for solar energy applications Research attention on solar energy storage has been attractive for decades. The thermal behavior of various solar energy storage systems is widely discussed in the literature, such as bulk solar energy storage, packed bed, or energy storage in modules.
Thermal energy storage can, for example, be implemented in heating networks in the form of Underground Thermal Energy Storage (UTES) to support the use of surplus heat from industry and the implementation of renewable heat sources such as bio-Combined Heat and Power (CHP), geothermal, and solar energy.
The thermal behavior of various solar energy storage systems is widely discussed in the literature, such as bulk solar energy storage, packed bed, or energy storage in modules. The packed bed represents a loosely packed solid material (rocks or PCM capsules) in a container through which air as heat transfer fluid passes.
Thermal energy storage (TES) systems store heat or cold for later use and are classified into sensible heat storage, latent heat storage, and thermochemical heat storage. Sensible heat storage systems raise the temperature of a material to store heat. Latent heat storage systems use PCMs to store heat through melting or solidifying.
CONCLUSIONS Thermal energy storage technologies need to be developed and become an integral component in the future energy system infrastructure to meet variations in both the availability and demand of energy.
