Representatives from alloy producers, original equipment manufacturers, end users and other industrial stakeholders will join NETL and other national laboratories to review research plans and progress during the virtual 2020 eXtremeMAT Industrial Stakeholder Meeting on Thursday, Oct. 15, 2020. Fossil energy transformational power technologies like ultra-supercritical steam plants and supercritical carbon-dioxide power systems have the potential to increase efficiencies and bolster clean coal efforts because they operate at higher temperatures and pressures. However, these technologies are subject to “extreme” operating environments – harsher and more corrosive conditions compared to those found in traditional power plants. Furthermore, today’s current fleet of fossil power plants are increasingly being subjected to cycling conditions due to the penetration of renewable energy sources into the electricity grid. Accelerating the development of improved steels, superalloys and other advanced alloys is of paramount importance in deploying materials solutions to address materials challenges associated with both the existing fleet and future power systems.
