The potential improvements that were analyzed include different receiver designs, different designs of the HTF-system and plant control, increased molten salt temperatures (up to 640°C) and multi-tower systems. Detailed technological and economic models of the solar field, solar receiver and high temperature fluid system (HTF-system) were developed and used to find potential improvements compared to a reference plant based on Solar Two technology and up-to-date cost estimations. The annual yield model calculates the annual outputs and the LCOE of all variants. An improved external tubular receiver and improved HTF-system achieves a significant decrease of LCOE compared to the reference. This is caused by lower receiver cost as well as improvements of the HTF-system and plant operation strategy, significantly reducing the plant own consumption. A novel star receiver shows potential for further cost decrease. The cavity receiver concepts result in higher LCOE due to their high investment cost, despite achieving higher efficiencies. Increased molten salt temperatures seem possible with an adapted, closed loop HTF-system and achieve comparable results to the original improved system (with 565°C) under the given boundary conditions. In this analysis all multi tower systems show lower economic viability compared to single tower systems, caused by high additional cost for piping connections and higher cost of the receivers.

K., Multi-Mirror Array Calculations With Optical Error The optical performance of a 2-axis solar concentrator was simulated with the COMSOL Multiphysics® software. The concentrator consists of a mirror array, which was created using the application builder. The mirror facets are preconfigured to form a focal point. During tracking all mirrors are moved simultaneously in a coupled mode by 2 motors in two axes, in order to keep the system in focus with the moving sun. Optical errors on each reflecting surface were implemented in combination with the solar angular cone of ± 4.65 mrad. As a result, the intercept factor of solar radiation that is available to the receiver was calculated as a function of the transversal and longitudinal angles of incidence. In addition, the intensity distribution on the receiver plane was calculated as a function of the incidence angles. 2019 5 Link direkt zum PDF-Download: https://www.comsol.jp/paper/download/856481/200918_SCO4_Paper_COMSOL_jg.pdf 1 6 weltweit https://www.comsol.com/paper/multi-mirror-array-calculations-with-optical-error-95421 Fachbereich Energietechnik OPUS4-9101 Konferenzveröffentlichung Sattler, Johannes, Christoph, sattler@sij.fh-aachen.de; Alexopoulos, Spiros, alexopoulos@sij.fh-aachen.de; Caminos, Ricardo Alexander Chico, chico-caminos@sij.fh-aachen.de; Mitchell, John C., ; Ruiz, Victor C., ; Kalogirou, Soteris, ; Ktistis, Panayiotis K., ; Teixeira Boura, Cristiano José, boura@sij.fh-aachen.de; Herrmann, Ulf, ulf.herrmann@sij.fh-aachen.de Dynamic simulation model of a parabolic trough collector system with concrete thermal energy storage for process steam generation 2019 NaN AIP Conference Proceedings 2126 150007-1 150007-8 10.1063/1.5117663 weltweit https://doi.org/10.1063/1.5117663 Fachbereich Energietechnik OPUS4-9100 Konferenzveröffentlichung May, Martin, may@sij.fh-aachen.de; Breitbach, Gerd, breitbach@fh-aachen.de; Alexopoulos, Spiros, alexopoulos@sij.fh-aachen.de; Latzke, Markus, latzke@sij.fh-aachen.de; Bäumer, Klaus, baeumer@sij.fh-aachen.de; Uhlig, Ralf, ; Söhn, Matthias, ; Teixeira Boura, Cristiano José, boura@sij.fh-aachen.de; Herrmann, Ulf, ulf.herrmann@sij.fh-aachen.de Experimental facility for investigations of wire mesh absorbers for pressurized gases 2019 NaN AIP Conference Proceedings 2126 030035-1 030035-9 10.1063/1.5117547 weltweit https://doi.org/10.1063/1.5117547 Fachbereich Energietechnik OPUS4-9098 Konferenzveröffentlichung Breitbach, Gerd, breitbach@fh-aachen.de; Alexopoulos, Spiros, alexopoulos@sij.fh-aachen.de; May, Martin, may@sij.fh-aachen.de; Teixeira Boura, Cristiano José, boura@sij.fh-aachen.de; Herrmann, Ulf, ulf.herrmann@sij.fh-aachen.de Analysis of volumetric solar radiation absorbers made of wire meshes 2019 NaN AIP Conference Proceedings 2126 030009-1 030009-6 10.1063/1.5117521 weltweit https://doi.org/10.1063/1.5117521 Fachbereich Energietechnik OPUS4-8989 Konferenzveröffentlichung Schwager, Christian, schwager@sij.fh-aachen.de; Teixeira Boura, Cristiano José, boura@sij.fh-aachen.de; Flesch, Robert, ; Alexopoulos, Spiros, alexopoulos@sij.fh-aachen.de; Herrmann, Ulf, ulf.hermann@sij.fh-aachen.de Improved efficiency prediction of a molten salt receiver based on dynamic cloud passage simulation 2019 NaN AIP Conference Proceedings 2126 978-0-7354-1866-0 1 030054-1 030054-8 10.1063/1.5117566 campus https://doi.org/10.1063/1.5117566 Solar-Institut Jülich OPUS4-9653 Konferenzveröffentlichung Sattler, Johannes Christoph, ; Chico Caminos, Ricardo Alexander, ; Atti, Vikrama Nagababu, vikrama.atti@sij.fh-aachen.de; Ürlings, Nicolas, ; Dutta, Siddharth, ; Ruiz, Victor, ; Kalogirou, Soteris, ; Ktistis, Panayiotis, ; Agathokleous, Rafaela, ; Alexopoulos, Spiros, alexopoulos@fh-aachen.de; Teixeira Boura, Cristiano José, ; Herrmann, Ulf, ulf.herrmann@sij.fh-aachen.de Dynamic simulation tool for a performance evaluation and sensitivity study of a parabolic trough collector system with concrete thermal energy storage Melville, NY American Institute of Physics 2020 6 Seiten AIP Conference Proceedings 2303 160004 10.1063/5.0029277 weltweit https://doi.org/10.1063/5.0029277 Solar-Institut Jülich OPUS4-9487 Konferenzveröffentlichung Sattler, Johannes, Christoph, sattler@sij.fh-aachen.de; Caminos, Ricardo Alexander Chico, ; Ürlings, Nicolas, ; Dutta, Siddharth, ; Ruiz, Victor, ; Kalogirou, Soteris, ; Ktistis, Panayiotis, ; Agathokleous, Rafaela, ; Jung, Christian, ; Alexopoulos, Spiros, alexopoulos@sij.fh-aachen.de; Atti, Vikrama Nagababu, vikrama.atti@sij.fh-aachen.de; Teixeira Boura, Cristiano José, boura@sij.fh-aachen.de; Herrmann, Ulf, ulf.herrmann@sij.fh-aachen.de Operational experience and behaviour of a parabolic trough collector system with concrete thermal energy storage for process steam generation in Cyprus 2020 NaN AIP Conference Proceedings 2303 140004-1 140004-10 10.1063/5.0029278 campus https://doi.org/10.1063/5.0029278 Fachbereich Energietechnik
