    Master-uppsats, KTH/Kraft- och värmeteknologi; KTH/Kraft- och värmeteknologi

    Författare :Maria Hallberg; Elin Hallme; [2019]
    Nyckelord :Solar energy; concentrating solar thermal; CST; central receiver system; CR; HelioPod; high-temperature process heat; manganese; business case; Solenergi; koncentrerad termisk solvärme; CST; soltorn; HelioPod; högtempererad processvärme; mangan; affärsmodell;

    Sammanfattning : The objective of this thesis was to investigate the potential for introducing a concentrating solar thermal (CST) central receiver plant system based on flexible heliostats - HelioPods - to provide high-temperature process heat in industrial applications. A CST plant system was designed in MATLAB, optically simulated for three design days in the ray-tracing software Tonatiuh and further analyzed in MATLAB by interpolating the results for each hour of the year.
