Abstract

This research investigates the feasibility of using Redcar Mudstone formation in the UK for carbon dioxide sequestration through mineral carbonation and enhanced weathering. Given the urgency of reducing atmospheric CO2 levels, it is essential to explore carbon dioxide removal methods such as mineral carbonation and enhanced weathering. These methods aim to accelerate natural CO2 reducing reactions involving alkaline minerals, potentially leading to the formation of stable carbonate minerals that can securely sequester CO2. The study conducted various experiments under different conditions, 1 high-pressure/temperature experiment, column experiment and CO2 incubator experiments. The results demonstrated that high pressure/temperature conditions were particularly effective for mineral carbonation, with the formation of stable calcite indicative of successful CO2 capture. The pH levels decreased across all experiments, confirming the acidification of the system and promoting further reactions with CO2. The research suggests that RM, with its abundant clay minerals, can be a suitable medium for CO2 sequestration through both mineral carbonation and enhanced weathering. RM’s potential reactivity and scalability make it a promising candidate for carbon capture technologies, offering a passive and continuous approach for CO2 reduction.
