  1. 1. Observing the radial velocity of the Sun with the AlbaNova heliostat

    Kandidat-uppsats, Stockholms universitet/Institutionen för astronomi

    Författare :Gustaf Beckman Berg; [2022]
    Nyckelord :;

    Sammanfattning : The aim of this project was to investigate the radial velocity variations of the Sun as observed from the Earth. This was accomplished by observing Doppler shifts of spectral lines in the region around 6300 Å. Telluric O2 lines were used as reference. LÄS MER

  3. 2. Structural Investigations of Novel Heliostat Designs based upon the Hydraulic Infinite Linear  Actuator (HILA)

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Venkata Nikhil Nandigama; [2021]
    Nyckelord :Structural Analysis; Heliostat; Mechanics; Topology optimization; Finite element methods; concentrated solar power; renewable energy.;

    Sammanfattning : A heliostat is a device that reflects the sun’s rays to a stationary object. There are two different types of heliostat serial and parallel type. The most used is the serial type of heliostat with Azimuthal-Elevation(Az-El) drive. LÄS MER

  4. 3. Introducing a central receiver system for industrial high-temperature process heat applications : A techno-economic case study of a large-scale CST plant system in a South African manganese sinter plant

    Master-uppsats, 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.

  5. 4. Concentrated Solar Thermal Plant for Future Fuels Production : Process Modeling and Techno-economic Analysis of Syngasoline, Syndiesel, Ethanol and Methanol Production Using Thermochemical Cycle based on Metal Oxide

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Philipe Gunawan Gan; [2018]
    Nyckelord :;

    Sammanfattning : Concentrated Solar Thermal technology (CST) is a very promising renewable energy technology and has a broad range of use. Conventionally, CST systems are mostly used for power generation according to the Rankine cycle and thus often referred to as Concentrated Solar Power (CSP). LÄS MER

  7. 5. On the Market Potential of Modular Stirling CSP Systems With Storage in the MENA

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Youssef Benmakhlouf Andaloussi; [2018]
    Nyckelord :;

    Sammanfattning : Given the intermittent nature of renewable energy sources, integrated storage solutions are necessary to accomplish the energy shift necessary for sustainable development. In the case of solar, PV-BESS tend to be highly capital intensive, especially for long storage hours most needed to guarantee stable electricity production day and night. LÄS MER
