Abstract Scope |
Concentrated solar power (CSP) receivers use solar energy to raise the temperature of a heat transfer fluid, that is used to generate electricity. To achieve the SunShot initiative’s 2030 target, next-generation CSP systems need to operate at a higher efficiency i.e. at outlet temperatures as high as 720 °C. Nickel-based alloys used in current-generation CSP receivers can underdo creep-fatigue damage accumulation at the operating temperatures of next-generation CSP receivers. The present study presents the viability of using ceramic materials that have better creep and dwell fatigue properties compared to Ni-based alloys. The study addresses the lack of methods and tools required for designing high-temperature receivers by presenting srlife, an open-source computational tool that models a CSP receiver and predicts its life in a time-dependent manner. The time-dependent failure arises when ceramics subjected to creep and fatigue loading undergo sub-critical crack growth that reduces their strength over time. |
