“…However, nitrate salts are limited to ≤600°C due to decomposition and corrosivity of the salt at higher temperatures . To be competitive in future markets perhaps with utility‐scale battery storage options, the third generation of CSP is envisioned to have a >50% thermal efficiency by using a supercritical CO 2 power block operating at >700°C . While a variety of thermal storage concepts can be considered, one strategy is to select a salt with higher temperature capabilities, such as chloride or fluoride salts, with chloride salts being favored due to lower costs .…”

“…Cheang et al compared three different sCO 2 power cycles (Recompression cycle, Partial cooling cycle and Combined cycle) against a steam Rankine cycle at both supercritical and superheated state in terms of cost and thermal efficiency when applied in CSP plants. His conclusions illustrated that sCO 2 power cycles are not a patch on the current steam Rankine technology . However, a modest maximum temperature of 580°C set in Cheang's comparison certainly attenuate the output of Recompression sCO 2 power cycle which takes on an advantage over 600°C .…”

“…Apparently, a solar field should provide more thermal power for the steam Rankine cycle which is the typical cycle of a solar power plant. The efficiency of the Rankine cycle depending on cycle characteristics is between 33% and 40% [9]. In this research, it was assumed that the pipes which are outside of the solar field are not insulated.…”
