This project aims to generate the knowledge and techniques required to increase carbon dioxide (CO2) uptake in hydrate based carbon capture from current levels of 15.4% to up to 90% of its rated capacity. This marked improvement stems from identification of the mechanism of CO2-water mass transfer in CO2 hydrate formation and engineering of structurally modified porous hydrogels as the substrate of CO2 hydrates. Encapsulation will be developed in a way that CO2 may be transported by CO2 hydrates in a concentrated form. Successful completion of the project will offer technical evaluation of a novel CO2 capture and transport solution with lower operational energy consumption and capital cost than incumbent carbon capture technologies.

该项目旨在产生所需的知识和技术，以将基于水合物的碳捕获中的二氧化碳（CO2）吸收量从目前的15.4%提高到其额定容量的90%。这一显着的改善源于CO2水合物形成和工程结构改性的多孔水凝胶作为CO2水合物的基板的CO2-水的传质机理的识别。将以一种可以通过浓缩形式的CO2水合物运输CO2的方式开发封装。该项目的成功完成将为新型二氧化碳捕获和运输解决方案提供技术评估，该解决方案的运营能耗和资本成本低于现有的碳捕获技术。
