There are a number of technical challenges that require attention
for sCO2 Brayton adoption in solar-thermal power generation.
They include a significant amount of work in development of
turbines, bearings, seals, heat exchanger design (especially when
considering salt to sCO2 heat exchange) and materials. The following
outlines several of the needs associated with this technology
adoption and are addressed here in an effort to provide a realistic
view regarding the path to implementation as well as a projection
of plant cost.
