Amino Acid Promotes Ultrarapid Clathrate Formation from Liquid CO 2 for Offshore Carbon Dioxide Sequestration

Achieving global net-zero emissions necessitates advancements in sustainable CO2 sequestration technologies. CO2 sequestration in subsea sediments in the form of clathrates presents a promising option due to inherent reaction conditions, high CO2 storage capacity, and superior stability. However, the sluggish CO2 hydrate formation kinetics significantly constrains its field-scale application, particularly in the process of CO2 hydrate cap formation to prevent the CO2 leakage. Herein, we propose a biomolecular strategy by using the low-dose hydrophobic amino acid l-methionine to address this challenge. Combining morphological imaging and in situ Raman spectroscopy, l-methionine was found to disrupt the rigid…
