Project Description

The objective is to complete the planning activities and the front-end engineering design (FEED) needed for conducting a full-scale pilot of select components at high-temperature and pressure at advanced ultra-supercritical (AUSC) conditions in the steam-turbine portion of a Component Test (ComTest) facility. These components will be made from advanced nickel-based materials identified and developed during a jointly-funded, multi-year DOE and Ohio Coal Development Office (OCDO) AUSC Consortium. The ComTest program will: 1) evaluate advanced materials and components under coal-fired AUSC conditions, demonstrate the reliability and safety of the boiler components; 2) demonstrate steam-turbine operation and valve reliability at AUSC conditions; 3) provide better understanding of the cost of an AUSC power plant to reduce project financial risk; 4) evaluate the constraints in the supply chain for advanced materials, including all necessary components, instruments, valves, and fittings; and 5) validate the fabrication techniques of the nickel alloys and the ability to construct, install, and reliably repair test components on site.

Project Benefits

Having safe and reliable materials that allow the use of advanced A-USC steam cycles in coal-based power plants could increase net efficiency from an average of approximately 35% (for the current U.S. fleet) to more than 45% on a higher heating value basis. These advanced materials and components could: 1) make coal power plants more competitive; 2) reduce water use; and 3) reduce CO2 emissions by approximately 20% compared to today’s fleet average.
