Project Description

NETL is partnering with Energy Industries of Ohio Inc. to demonstrate advanced ultrasupercritical (AUSC) technology at a commercial-scale level of technology readiness by designing, procuring, constructing, and operating a test facility consisting of a prototype R&D-scale (approximately 134,000 lb/hr steam flowrate, which is equivalent to 20 MW power generation) AUSC steam turbine and other AUSC plant components needed to generate the steam to run the prototype-scale steam turbine. The project will complete planning activities and front-end engineering design for conducting full-scale pilot testing of select components at high temperatures and pressures.

Project Benefits

The expected benefits of the project will be the development of a domestic supply chain for the fabrication of nickel superalloy and other AUSC power plant components; validation through design, fabrication, and operation of a prototype (20 MW) scale unit; validation that an AUSC steam turbine can be designed, built, and reliably operated under both steady-state and varying load operating conditions; development and validation of fabrication, installation, and repair methods for nickel superalloy and other AUSC power plant components; and the obtaining of sufficient R&D test and metallurgical analysis data to design an AUSC demonstration plant with a high probability of technical success.
