“…The same gas could be used for heating up the solid storage as well as for the gas cycle [16]. In particle receiver systems, moving bed HX are developed with particles flowing through tubes on one side and gas or steam being heated up on the other side [17], [18]. …”

“…SAM has several capabilities to study different types of CSP systems, such as those with molten salt [ 12 ], but particle receivers are not included. Thus, a few in-house software have been developed with the objective of analyzing the economics of particle systems [ 13 , 14 , 15 ]. Ma et al [ 13 ] showed a first estimation of the LCOE estimation in a particle system, although the model was barely explained.…”

Ma et al [ 13 ] showed a first estimation of the LCOE estimation in a particle system, although the model was barely explained. Buck et al [ 14 ] presented in 2018 a model of multi-tower CSP systems with centrifugal particle receiver to analyze the LCOE trends under different conditions.…”

Particle receivers are one of the candidates for the next generation of CSP plants, whose goal is to reduce the levelized cost of electricity (LCOE) to 0.05 $/kWh. This paper presents a techno-economic analysis to study if a CSP system with free-falling particle receiver can achieve this goal. The plant analyzed integrates two ground-based bins to store the excess energy and a supercritical CO2 cycle to generate electricity. The model used for the analysis presents several upgrades to previous particle systems models in order to increase its fidelity, accuracy, and representativeness of an actual system. The main upgrades are the addition of off-design conditions during the annual simulations in all the components and an improved receiver model validated against CFD simulations. The size of the main components is optimized to obtain the system configuration with minimum LCOE. The results show that particle CSP systems can reduce the LCOE to 0.056 $/kWh if the configuration is composed of 1.61 × 106 m2 of heliostats, a 250 m high tower with a 537 m2 falling particle curtain, and 16 h thermal energy storage.

“…The concept of NREL [8,9] also follows a near black body approach, but particle flow through the receiver is gravity driven. With a fluidized bed a controlled particle flow can be realized, minimizing the risk of hot spots and maximizing the heat transfer coefficients of particle flows.…”
