Development of a carbonate-based direct air capture approach

This project aims to develop a potential approach to removing carbon dioxide from ambient air. The approach involves using lime (CaO) in various applications, which results in carbon dioxide being permanently removed from the atmosphere. There are three aspects that this project would address: (i) the rate and extent of the carbonation reaction of the lime generated in a novel production process (ii) a techno-economic analysis of the production of zero-carbon lime as a function of location (iii) an analysis of the uses of the zero-carbon lime in a range of applications, to assess the potential co-benefits of such applications and by extension determine the cost of removing carbon dioxide from the atmosphere. Together, an analysis of these three aspects determines the cost and scalability of using lime to remove carbon dioxide from the atmosphere.
