In the Advanced UltraSuperCritical (AUSC) coal-fired power plants project sponsored by the US Department of Energy and the Ohio Coal Development Office, a consortium of companies including Alstom Power, Babcock & Wilcox, Foster Wheeler, Riley Power, Electric Power Research Institute, Oak Ridge National Lab, and Energy Industries of Ohio have carried out an extensive program to evaluate the steamside oxidation, fireside corrosion, and fabricability of the alloys selected for AUSC plants. As a result, the major enabling technology for these AUSC plants is the availability of materials with high creep strength, corrosion resistance, and fabricability.
