HEAT STORAGE

摘要

Solar heat collected during the day can be stored in liquid or solid media such as molten salts, ceramics, concrete or phase-changing salt mixtures. At night, it can then be extracted to keep the turbine running. Thermal power plants with solar-oniy generation work well supplying summer midday peak loads in wealthy regions with significant cooling demands, such as Spain and California. With thermal energy storage systems they oporate longer and even provide base-load power.
