Abstract

Higher process temperatures and pressures are mandatory to increase network efficiency and reduce CO2 emissions”, to follow the results of the COPIT 2016 conference.  As a consequence of these more severe operating conditions requires better materials with higher demands for development, manufacturing, and fabrication. This paper summarizes the current status of the art of the materials for Ultrasupercritical coal-fueled power plants and the trend for the development needed for the next generation called “advanced Ultrasupercritical” targeting >50% efficiency, where nickel-base superalloys will be necessary for the hottest part of the plant.

This new generation of power plants will give an effort for the reduction of CO2 emission because forecasts confirm that coal will be the most relevant source for energy production at least for the next 30 years.
