Particle-based solar thermal energy storage (TES) coupled to concentrated solar power (CSP) is an attractive pathway towards operating at elevated temperatures while extending electricity production beyond diurnal periods of on-sun operation. Operation at elevated temperatures necessitates higher solar concentration ratios at MWth-scales that are only possible with power towers and heliostat fields.
Particle-based Solar Energy Capture and Storage for Concentrated Solar Power
These elevated temperatures are facilitated by particle-based solar thermal energy storage systems due to effective absorptance of concentrated solar irradiation, chemical inertness, and thermal stability combined with high heat capacities. The operating principles of a TES integrated CSP system are direct or indirect heating of particles entering a solar receiver from cold storage tank via exposure to concentrated solar irradiation, which results in an increase in temperature as sensible heat is stored; transfer to a hot storage tank for use when required; conveyance and integration into a heat exchanger where the particle heat is transferred to a fluid drive a power cycle and produce on-demand electricity; and subsequent storage in a cold tank to complete the cycle.
Numerous advances have been made in particle-based solar TES integrated with CSP to make them less expensive, more efficient, and capable of longer continuous operation. A principal enabler has been extensive research and technology development of subcomponents, including solar receivers, storage tanks, and heat exchangers. The development of these technologies is supported by fundamental work aimed at determining key properties for understanding flows, heat and mass transfer, and particle attrition.
