Published at Renewable Energy – The performance evaluation of the free-falling particle solar receiver with a novel zigzag mass-flow controlled particle release pattern

Abstract: A free-falling particle receiver is a promising technology to be used in concentrating solar power plants. In this study, an optical-thermal coupled model is established by combining a Monte Carlo ray-tracing method with a finite volume method to simulate the energy transfer processes in a solar power tower system employing a cavity receiver. Using …

Two CSP studies quantify a trade-off between solar efficiency and LCOE

Vast Solar is one of the few commercial firms numbering-up modules in CSP. Efficiency or LCOE: which is more important to reduce the cost of Gen-3 CSP systems? A pair of related papers from ANU in Australia compare the value of efficiency versus Levelized Cost of Energy (LCOE) in Concentrated Solar Power (CSP) systems. The …
