    Keywords : solar thermal power; steam-turbine; start-up; cool-down; dispatchability increase; koncentrerad solenergi; ångturbin; uppstart; nedkylning; ökad flexibilitet;

    Abstract : The provision of a sustainable energy supply is one of the most important issues facing humanity at the current time, given the strong dependence of social and economic prosperity on the availability of affordable energy and the growing environmental concerns about its production. Solar thermal power has established itself as a viable source of renewable power, capable of generating electricity at some of the most economically attractive rates. READ MORE

  7. 20. Preparation and Characterization of Sputter Deposited Spectrally Selective Solar Absorbers

    Author : Kristina Gelin; Ewa Wäckelgård; Arne Roos; Björn Karlsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; spectrally selective solar absorber; thermal emittance; solar absorptance; sputter deposition; infrared reflectance; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : The optical efficiency of a commercially available sputter deposited spectrally selective solar absorber was improved. The main purposes were to decrease the thermal emittance, increase the solar absorbtance of the absorber and to protect the substrate from degradation due to environmental influence. READ MORE
