Customer ServiceStorage helps solar contribute to the electricity supply even when the sun isn''t shining. It can also help smooth out variations in how solar energy flows on the grid. These variations are attributable to changes in the amount of sunlight that shines onto photovoltaic (PV) panels or concentrating solar-thermal power (CSP) systems.
Customer ServiceThermal energy storage is a key enable technology to increase the CSP installed capacity levels in the world. The two-tank molten salt configuration is the preferred storage technology, especially in parabolic trough and solar tower. By 2020, the plants without storage will be just 30% of the total installed capacity.
Customer ServiceCoupling solar energy and storage technologies is one such case. The reason: Solar energy is not always produced at the time energy is needed most. Peak power usage often occurs on summer afternoons and evenings, when solar energy generation is falling.
After the receiver captures the heat on the HTF, the thermal energy is transported either for conversion or for storage. Thermal energy storage provides a workable solution to the reduced or curtailed production when sun sets or is blocked by clouds (as in PV systems).
The solar thermal energy storage efficiency η experiment of the MOST system has been determined to reach up to 2.3%, representing the highest recorded efficiency to date. 34 Additionally, the inclusion of the MOST system as a non-heating temperature stabilizer with optical filter effect can further enhance the efficiency of the PV cell.
Depending on the storage material chosen, any configuration must be able to store the required amount of energy within the duration of application and should be economical. In terms of thermal performance, it is critical that the storage system has high energy density and has adequate charging and discharging rate capability.
Component level – This level of design pertains to the selection of the basic components that are used for forming the thermal energy storage system, including storage material, type of contact and heat transfer between the storage material and the HTF, and any heat transfer enhancements to be incorporated. 3.
Active two-tank systems The principal elements for a two-tank thermal energy storage system are the material inventory, HTF, heat exchangers and the storage tanks, apart from the storage material circulation pumps. During charging, the amount of heat stored in the fluid depends on the heat supplied by the solar field.
