Abstract

The Carbon Capture Simulation Initiative (CCSI) is developing technology to accelerate the process of making carbon capture from coal-fired power plants reliable and affordable by using simulation to reduce the need for physical testing for scaling up to commercial scale. Uncertainty quantification (UQ) capability is critical to simulation-based analysis of carbon capture systems for understanding and managing the complexity and economic impact of incorporation of carbon capture systems in current and future commercial operations. These uncertainty quantification tools include input sensitivity analysis, calibration of inputs, construction of surrogate models, and propagation of uncertainty. This talk will illustrate the use of selected UQ concepts in early stage development and evaluation of requirements for effective simulation of a solid sorbent process for carbon capture.
