Review of the spectrally selective (CSP) absorber coatings, suitable for use in SHIP

A key component in the conversion process of concentrated solar power (CSP) into thermal energy is a absorber coating. Many experimental and simulated coatings for various substrates CSP water/steam or molten salt absorbers have been developed. The main challenges today remain selection low-cost effective fabrication method, appropriate industrial production, assessment degradation rate service life these coatings, which affect efficiency plant LCOE. In this article, we review different types mid- (100 < T 400 °C) high-temperature (>400 their methods. emphasis on absorptance, emittance long-term (>10 years) stability coatings. Spectral selectivity more difficult expensive than other means, was proven to be essential low-to-mid temperature range low concentration ratios, yet high temperatures absorptive can achieve same even better performance spectral selective ones. Important factors an efficient are compatibility coating substrate under cyclic conditions heat transfer medium.
