Two concentrated solar power (CSP) concepts utilizing supercritical carbon dioxide (sCO2) Brayton cycle are dynamically simulated and compared regarding their overall performance and detailed sub-process behaviour. Concept 1 uses sCO2 both as heat transfer fluid (HTF) in the solar field and as working fluid in the power cycle, whereas Concept 2 uses molten salt as HTF and additionally takes advantage of a two-tank molten salt storage system to guarantee continuous power production. Concept 1 has been studied before, whereas Concept 2 presents a novel idea to combine high efficiency of sCO2 as the working fluid and the dispatchable nature of molten salt solar systems. Dynamic simulation software Aprosr was used to model and simulate the concepts, providing detailed results and insights on the system behaviour.
