Abstract

There are many similarities between the high-temperature materials issues for supercritical CO₂ (sCO₂) and conventional coal-fired steam boilers with the major difference being compatibility or environmental issues in steam versus CO₂. Likewise, for high-efficiency (>700°C) sCO₂ systems, recent work has addressed many of the mechanical properties issues as well as joining and fabrication for Ni-base alloys and particularly the strongest precipitation-strengthened alloys 740 and 282. Therefore, this chapter focuses on the unique environmental issues including a thermodynamic analysis of oxidation in sCO₂, which suggests there could be internal carburization that could degrade mechanical properties. There is not a large database available on compatibility in sCO₂, particularly above 650°C and many issues remain to be addressed. However, if system pressure does not significantly impact compatibility, a large database of performance in 0.1-4MPa CO₂ has been developed over the past 50years.
