Electrochemical Upcycling of Waste Cement: High-Performance Cement Production and Air Carbon Dioxide Removal

Executive Summary

We will develop an electrochemical method to capture air carbon dioxide, while generating hydrogen gas and valuable byproducts, by dissolving waste cement. This research will have broad application to clean energy and climate security by consuming the solid waste generated during construction, producing low-carbon cement, and reducing the cost of hydrogen production and carbon capture.
