Symposium Materials Degradation in Supercritical CO2 Power Cycles
Organizer(s) Omer Dogan, DOE National Energy Technology Laboratory

Scope Supercritical carbon dioxide (sCO2) cycles are proposed for concentrated solar, nuclear, fossil, and other power generation systems for their higher efficiencies, smaller equipment size, and reduced water usage. Conditions of the working fluid (sCO2 at high temperatures and high pressures) in these cycles create challenging environments for materials of construction. Chemical and mechanical stability of power plant materials in sCO2 cycles is currently a subject of numerous research projects. This symposium will bring together materials experts working on sCO2 cycles and provide a forum for the materials research conducted on this subject. Abstracts are invited in the areas including, but not limited to, corrosion, erosion, and mechanical behavior of materials and joined materials in sCO2 environments.
