Increasing the Cost Effectiveness of CSP Technologies Through the Development of a New CLFR “Etendue Matched” Collector

Abstract

A new CLFR “Etendue Matched” is a promising CSP technology to achieve a better cost effectiveness with a lower levelized cost per m2 . This new technology can significantly reduce shading and blocking existing in a conventional LFR (Chaves, 2009; Chaves, 2010), while at the same time optimizing primary and secondary concentration to the limits allowed by first principles in optics. A preliminary evaluation of the optical and thermal performance has been performed (Canavarro, 2010, Horta 2011), and a configuration for a full scale CSP power plant proposed, with two secondary receivers (Fig.1), i.e a multiple receiver solution.
