“…8 and 9 for alumina and sintered bauxite, which indicates a high lifetime expectancy with cyclic thermal loads. 1 From analysis of the shape factor (shown in Fig. 12), it can be seen that not only is the grain size distribution of the ceramic materials unaffected by thermal shock, but the grains did not undergo any change of shape at all, which underlines the observed resistance to thermal shock.…”

“…One promising approach is the application of fine-grained particulate materials as the storage and heat transfer medium in Central Receiver Systems (CRS). As an advantage, granular materials allow for high process temperatures in CSP systems (4 600°C) and can be used both as heat transfer and heat storage media, which offer higher power plant efficiencies and also a potential cost reduction in comparison to molten salt, which is today's most common heat transfer fluid used in CSP [1].…”

The minimal drift between the grain size distribution curves is caused by uncertainties of the measurement method: none of the product's grain size distributions are homogeneous, and the number of grains on each substrate is limited.…”

a b s t r a c tA selection of granular natural and ceramic materials has been experimentally characterized with regard to their application as heat transfer and storage media in concentrating solar power plants. Thermophysical, thermomechanical, tribological and rheological measurements have been conducted in order to identify the most suitable candidates for this dynamic high temperature operation. Ceramic materials are found to comprise some advantages, but natural products offer a considerably more economic solution. Thermal bulk conductivity is found to be only marginally affected by the solid's thermal conductivity, while specific heat is the same for all solids. Ceramics entirely withstand thermal cycling, while quartzcontaining materials are prone to severe degradation. Most materials are found to attain a saturated state of attrition while being sheared under load, wherein quartz sand offers the lowest mass fraction of debris at saturation level. In the investigated grain size range, all materials show good flowability. The generation of debris requires consideration in the design of the CSP storage components.

“…The design raises the particle temperature via indirect heat exchange. [5] The development of the SPR involves investigation into a number of important elements regarding design, manufacturing, material selection and operation of this receiver. Among these are the evaluation of particle flow and heat transfer, material selection and testing, characterization of optical performance related to flux penetration, spreading and losses as well as determining its manufacturability and operability.…”

Solar Particle Receivers (SPR) are under development to drive concentrating solar plants (CSP) towards higher operating temperatures to support higher efficiency power conversion cycles. The novel high temperature SPR-based CSP system uses solid particles as the heat transfer medium (HTM) in place of the more conventional fluids such as molten salt or steam used in current state-of-the-art CSP plants. The solar particle receiver (SPR) is designed to heat the HTM to temperatures of 800 °C or higher which is well above the operating temperatures of nitrate-based molten salt thermal energy storage (TES) systems. The solid particles also help overcome some of the other challenges associated with molten salt-based systems such as freezing, instability and degradation. The higher operating temperatures and use of low cost HTM and higher efficiency power cycles are geared towards reducing costs associated with CSP systems. This paper describes the SPR-based CSP system with a focus on the fluidized-bed (FB) heat exchanger and its integration with various power cycles. The SPR technology provides a potential pathway to achieving the levelized cost of electricity (LCOE) target of $0.06/kWh that has been set by the U.S. Department of Energy's SunShot initiative.

Current concentrated solar power (CSP) plants that operate at the highest temperature use molten salts as both heat transfer fluid (HTF) and thermal energy storage (TES) medium. Molten salts can reach up to 565°C before becoming chemically unstable and highly corrosive. This is one of the higher weaknesses of the technology. Solid particles have been proposed to overcome current working temperature limits, since the particle media can be stable for temperatures close to 1000°C. This work presents a review of solid particles candidates to be used as HTF and TES in CSP plants in open receivers. In addition, the interactions between solid particles with major system components are described in this review, for example, with TES system or heat exchanger. The parameters and properties of solid particles are identified from the material science point of view explaining their nature and the relation to the power plant efficiency and lifetime durability. Finally, future development is proposed; such as material selection according to each specific design, materials characterization, or durability test.
