Note:
The overarching goal of this project is to understand and control the chemical reactions that govern hydroxylation and carbonation processes during Direct Air Capture (DAC) of CO2 using magnesium oxide (MgO). This will be done by resolving three gaps in our fundamental understanding that inhibit our ability to capitalize on this promising method to capture dilute CO2 on the Gton scale. Specific Aim #1 What are the chemical reactions that control the rate and extent of reaction of MgO with CO2 at ambient conditions and varying humidity? By understanding these, we will be able to predict and control the rate and extent of the reactions. Specific Aim #2) What are the mechanisms of reaction-induced fracturing during MgO hydroxylation? Specific Aim #3) What are the roles of impurities in affecting the hydroxylation, carbonation, and oxide regeneration reactions? We will combine batch experiments, advanced x-ray/neutron scattering and chemical imaging with atomic to meso-scale phase field modeling approaches to answer these specific aims. By achieving this goal, we will enable direct air capture of CO2 on the Gt-scale. With the proposed research we will meet critical needs described in the Carbon Negative Earthshot and the BES roundtable “Foundational Science for Carbon Dioxide Removal Technologies”, specifically, the Priority Research Opportunities (PRO) PRO1 “Master Interfacial Processes of CO2 Transport and Reactivity Across Multiple Length and Time Scales” and PRO4 “Control Multiphase Interactions Required for CO2 Conversion into Molecules, Minerals and Materials”.
