Materials Issues in Supercritical Carbon Dioxide


Performer: ORNL - Oak Ridge National Laboratory

Project No: FWP-FEAA112


Project Description

The proposed work is focused on establishing a broad understanding of the materials issues associated with scaling up supercritical carbon dioxide (sCO2) systems to higher temperatures in order to increase the efficiency of commercial power production. The effort is intended to increase understanding of the applicable 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) to enable materials selection and design of sCO2 systems.
