Carbon dioxide-methane exchange in porous media for carbon-neutral energy production

该项目旨在将碳捕获和封存纳入能源储备中的天然气生产。碳封存可有助于实现《巴黎气候协定》的目标。向天然气储气库或甲烷水合物砂中注入二氧化碳将是一种近乎碳中性的能源生产方式。然而，在储集层和砂岩中，人们对二氧化碳和甲烷的这种交换知之甚少，因为水和砂子等多个相影响混合和回收。该项目将高压注水的空间分辨磁共振成像和交流实验与多尺度模拟相结合。预期的结果是在提高能源生产的同时实现二氧化碳封存。

This project aims to incorporate carbon capture and storage into natural gas production from energy reserves. Carbon sequestration could assist in achieving the goals of the Paris Climate Agreement. Injecting carbon dioxide into natural gas reservoirs or methane hydrate sands would be a nearly carbon-neutral means of energy production. However, this exchange of carbon dioxide for methane is poorly understood in both reservoirs and sands because multiple phases like water and sand affect mixing and recovery. This project will combine spatially-resolved Magnetic Resonance Imaging of high-pressure flooding and exchange experiments with multi-scale modelling. The expected outcome is simultaneous carbon dioxide sequestration with enhanced energy production.
