Thermal energy storage technologies for concentrated solar power
High-temperature storage concepts in solar power plants can be classified as active or passive systems [29]. An active storage system is mainly characterised by the storage media circulating through a heat exchanger, using one or two tanks as the storage media. Active systems are subdivided into direct and indirect [29].
