The use of molten salt in line focusing systems is under investigation by several CSP market players along the supply chain of a typical CSP-plant. In this paper, an economical analysis is performed, in order to compare the DMS system with a DSG-system with solid bed thermal storage and a classical parabolic trough system using thermal oil and a molten-salt storage system. The resulting LCOE values are further analyzed with a sensitivity analysis and further technical and operational optimization. As results, the economical values for the DMS show a good potential. The DSG-system with solid bed as thermal storage offers also a high and promising potential to achieve even clear lower LCOE-values, with very stable LCOE-level with regard to the sensitivity analysis. As one outcome of this study, the LCOE values for the DMS and the DSG-system are in any case lower compared to current state of the art solutions.

“…Each configuration was optimized for lowest LCOE by determining the optimum field size and storage capacity. The Ultimate Trough collector was chosen due to its high optical efficiency and large aperture, which lead to optimum thermal loss characteristics for high-temperature applications with molten salt ([1], [2]). …”

While the positive effect of raising turbine inlet temperature to increase overall plant efficiency is often quoted and discussed, another figure is mentioned to a much lesser extent: The HTF outlet temperature at the steam generator exit, which also has a profound influence on cycle efficiency due to the fact that allowing higher temperatures allows moving to much higher evaporator pressures and, thus, higher cycle efficiencies. This paper aims at evaluating potential benefits of increasing the lower HTF temperature in molten salt parabolic trough power plants based on an evaluation of its influence on LCOE.
