  • Molten salt for parabolic trough applications: system simulation and scale effects

    The trend of solar thermal power plant engineering towards lower investment and energy costs leads to a demand for higher operating temperatures in the plant cycle. The use of molten salts withstanding temperatures up to 550 °C is considered for use in CSP plants, in particular for parabolic trough systems. In thermal storage systems fluids as “Solar Salt” (NaNO3/KNO3) are already ...

  • Exergy analysis of DSG parabolic trough collectors for the optimal integration with a combined cycle

    A comprehensive energy and exergy analysis was conducted for various components of a direct steam generation (DSG) parabolic trough solar collector field under nominal operating conditions to assess performance of the components and to optimally integrate them with a thermal system. The solar field was modelled mathematically to compute thermal loss and consequently the thermodynamic ...

  • Let us make our planet as solar paradise

    We should think to create happy planet. But first of all we should think what we mean by happy planet. Very nice wide highways connecting big cities is not the sign of happy planet. Big cities with tall buildings is not the sign of happy planet. Fast air conditioned trains and planes is not the sign of happy planet. Big factories producing mass products is not the sign of happy ...

  • SCHOTT’s 4th Generation Receiver - Getting ready for higher operation temperatures

    Parabolic Trough Technology needs to push performance to the limits to achieve a solar field system with improved economics. The collector system with the receiver as an energy converter mainly affects the field performance by optical parameters, yet oil- HTF, which is not stable at temperatures beyond 400°C, is limiting overall power plant efficiency improvements. High temperature HTFs are ...

  • Morocco leans on Renewable Energy

    Morocco has no gas or oil gas resources on its territory. Therefore, the realm has to import about 90% of its electricity, totaling about one quarter of its overall importation. Buying energy from oversea is a huge investment for the country and Morocco is now turning to renewable energy to become self-sufficient in terms of energy. The country will soon produce its own energy, mainly through ...
