The sCO2 Brayton cycle has been shown to have significant effi-
ciency benefits especially as solar-thermal power plants increase
their operating temperatures above 600 C. In particular, part heat
load operation, common to a solar resource, appears manageable
especially for short durations (e.g. short-term cloud cover) due to
thermal capacitance in the system and piping. Therefore it is recommended
that sCO2 Brayton cycles continue to be pursued for solar-thermal
energy applications.
