After 17 years of research involving NETL, industry partners, and a high-tech research group known as the AUSC Consortium, significant progress is being made toward scaling up the fabrication of components made from advanced nickel superalloys that will help bring advanced ultrasupercritical (AUSC) power plant technology to the level of readiness for commercial-scale demonstration. In the 1950s, coal-fired power plants operated at a then cutting-edge steam pressure of 2,400 psi and main steam temperatures of up to 538 degrees Celsius (C). They were known as “subcritical.” Increasing the pressure and temperature of a power plant can increase power plant efficiency, and by the end of the 20th century, new coal-fired power plants were designed for “supercritical” steam conditions where steam conditions and power plant efficiency were as high as 610 degrees C, 4300 psia and 41 percent. Further, increases in power plant efficiency continue to be sought to reduce the cost of power generation and carbon capture. A new generation of AUSC power plants is viewed as a promising way to attain those goals.
