Materials Issues in Supercritical Carbon Dioxide
Performer: ORNL - Oak Ridge National Laboratory
Project No: FWP-FEAA112
Program Background and Project Benefits
This project will establish a broad understanding of the materials issues associated with scaling up supercritical carbon dioxide (sCO2) systems to higher temperatures. These higher temperatures will increase the efficiency of commercial power production. Specifically, this project will build and validate a materials testing rig and test corrosion mechanisms in sCO2 as a function of temperature and establish temperature limits for various classes of materials (e.g., ferritic and austenitic steels, Ni-base alloys, and alumina-forming alloys) for sCO2 systems.
