Materials Issues in Supercritical Carbon Dioxide

Performer: ORNL - Oak Ridge National Laboratory

Project No: FWP-FEAA112

Project Description

This Oak Ridge National Laboratory project is focused on establishing a broad understanding of the materials issues with scaling up supercritical carbon dioxide (sCO2) systems to higher temperatures for increased efficiency commercial power production. The effort is intended to understand the applicable corrosion mechanisms in sCO2 as a function of temperature and to establish temperature limits for various classes of materials (e.g. ferritic and austenitic steels, Ni-base alloys, alumina-forming alloys) to enable materials selection and design of sCO2 systems.
