专题征稿 | Underground Carbon Capture and Sequestration (UCCS)

In 2015, one of the most ambitious climate change meetings convened in France, bringing together representatives from over 190 countries. It culminated in the signing of the 2015 Paris Climate Agreement. The primary objective of this agreement is to prevent a global temperature increase of 2 °C above preindustrial levels and to strive towards achieving a more ambitious goal of stabilizing temperatures at 1.5 °C. In light of the current situation, achieving not only net-zero but also negative greenhouse gas (GHG) emissions by 2080 becomes imperative to curb the global temperature rise within the desired limits. Addressing this challenge necessitates more than a cessation of the use of existing energy resources, as that would impede overall progress and development. While transitioning to green and renewable energy is crucial and achievable in the coming decades, during this transitional phase, the storage of carbon dioxide (CCS) in underground geological reservoirs emerges as a primary technology to mitigate the escalating carbon footprint.

• Theoretical and experimental investigation of physico-chemical, mechanical and flow properties of unconventional energy systems with emphasis on alterations as a result of exposure to CO₂, across scale. These studies should aim to delineate the interacting forces between minerals, organics, and fluids at elevating pressure and temperature.

• Studies that improve our fundamental understanding of carbon capture mechanisms and adsorption phenomenon in organic-rich (shale and coal) layers from molecular perspective, based on simulation or experiments.

• Risk-assessment methods, and real-world application of artificial intelligence/machine learning and data science in successful implementation of CCS or the prediction of the formation response, particularly in shale layers and coal beds.
