A review on the role of amino acids in gas hydrate inhibition, CO2 capture and sequestration, and natural gas storage

Natural amino acids have been introduced as potential additives for gas hydrate inhibition, natural gas storage, and CO2 capture and sequestration. Herein, almost all amino acids hydrate-based additives are critically reviewed. The hydrate inhibition/promotion effect of each amino acid and factors that affect their performance on gas hydrate formation are discussed. Furthermore, amino acids hydrate inhibition/promotional mechanism and modelling studies are reviewed. Detailed comparison between amino acids and convention hydrate additives alongside future directions towards amino acids hydrate-based technology commercialization are also discussed. The findings presented in this work are relevant for future amino acids breakthrough research in hydrate-based technologies.
