Lifetime Model Development for Supercritical Carbon Dioxide Concentrating Solar-Thermal Power Systems

This project seeks to develop a predictive lifetime model for materials in supercritical carbon dioxide (sCO2) conditions similar to concentrated solar power (CSP) applications. Experimental work will generate relevant corrosion, creep, and fatigue data to populate the model and then verify model predictions. The test campaign will mirror the thermal cycling expected in CSP applications. The combination of experiments aims to remove the many unknowns of how sCO2 and its containment material will function over the expected lifetime of a power plant.
