“…Similar to the leucine system, changing the methionine concentration has no effect on the gas uptake or the water to hydrate conversion as it is reportedly a KHP, as shown in Figure c. The results are consistent with literature that surfactants only serve as kinetic promoters for hydrate formation and have no effect on the final gas uptake. , Methionine concentration of 1.00 wt % results in the highest average final gas uptake of 85.96 ± 1.69 mmol CO 2 /mol of water and water to hydrate conversion of 53.30 ± 1.05%.…”

“…This wall-climbing effect is influenced by capillary action, in which solution is drawn upward from the bulk liquid to the hydrate formation reaction interface via capillary channels formed on the reactor wall. 38,39 Ten minutes after induction, the start of hydrate growth in the bulk solution is observed (Figure 2D). Twenty minutes after nucleation, the hydrates completely cover the observation window, with the origin of vein-like formation indicating hydrate thickening, as shown in Figure 2F.…”

“…The results are consistent with literature that surfactants only serve as kinetic promoters for hydrate formation and have no effect on the final gas uptake. 19,38 Methionine concentration of 1.00 wt % results in the highest average final gas uptake of 85.96 ± 1.69 mmol CO 2 /mol of water and water to hydrate conversion of 53.30 ± 1.05%. Figure 4 shows the average gas uptake profile and observed morphology during CO 2 hydrate formation in the presence of 1% methionine at 3 MPa and 273.2 K. It should be noted that the hydrate formation morphology at 1.00 wt % methionine was chosen as a representative for CO 2 hydrate formation morphology since the methane hydrate formation at other methionine concentrations also exhibit a similar formation pattern, as demonstrated in Figure S3 in the Supporting Information.…”

Carbon capture and storage (CCS) is a promising method for reducing carbon dioxide (CO2) emissions, while the use of fossil fuels is still needed. A hydrate-based technology has gained attention for CCS applications since it provides various advantages, particularly in terms of energy efficiency. However, the slow kinetics of CO2 hydrate formation without promoters has been a challenge for CCS on an industrial scale. In this study, amino acids including leucine, methionine, and valine were used as promoters to investigate their effect on the CO2 hydrate formation using a hybrid combinatorial reactor (HCR) configuration. The amino acids were tested at different concentrations. The results showed that the addition of amino acids had varying effects on CO2 hydrate formation kinetics. The highest rate of hydrate formation was observed in the methionine system. The amino acids and their concentrations had no significant impact on the gas uptake or the conversion of water to hydrates. All systems displayed a similar pattern of hydrate formation morphology. There was no foam formation during the hydrate dissociation, and the hydrate reformed in the reused solution had almost the same gas uptake as the fresh solution. Overall, the use of amino acids with the HCR approach may be a promising option for CCS applications.

“…In this direction, sodium dodecyl sulfate (surface-active chemistries) − and tetrahydrofuran have been considered the best kinetic and thermodynamic promoters, respectively. − However, the biocompatibility of such chemicals and their impact on marine life have been the major challenges for their deployment in HBS processes. Recently, a new category of biocompatible chemistries such as amino acids , and biosurfactants has been broadly researched for their hydrate promotion and inhibition characteristics. − Alike the surfactants, amino acids promote hydrate formation while employing the hydrophilic and hydrophobic moieties (e.g., carboxylic acid, amine groups, and a side chain). Cai et al reported significant improvement in the kinetics of CO 2 hydrate formation (CO 2 storage ∼356 mg/g or 84% water-to-hydrate conversion) in a static reactor while adding l -methionine amino acid (0.2 wt %) to water.…”

To achieve the United Nations Climate Change Conference (COP-26) targets of net zero carbon emissions, hydrate-based carbon dioxide (CO 2 ) capture and sequestration (CCS) can be considered one of the potential sustainable technologies. However, the sluggish kinetics of CO 2 hydrate formation in the saline subsea environment and the nonecofriendly nature of the existing additives (kinetic promoters) are the major challenges. Therefore, to intensify the kinetics, the performance of the biocompatible hydrophobic amino acid Lleucine for CO 2 hydrate formation/dissociation was evaluated using the simulated subsea sediment of silica sand. Experiments were performed in saline (3.0 wt % NaCl) and nonsaline environments with L-leucine (0.1−1.0 wt %) at 3.2 ± 0.2 MPa pressure and 274.5 ± 0.2 K temperature. With the addition of 0.5 wt % L-leucine to freshwater, water-to-hydrate conversion of 73.01 ± 4.96% (44.08 ± 2.95% gas-to-hydrate conversion) was achieved with a rate of gas uptake of 4.25 ± 0.39 mmol/min, which is ∼10 times higher compared to the baseline (no promoter). Though salinity significantly reduced the hydrate formation kinetics, the addition of 1.0 wt % L-leucine intensified the rate of CO 2 uptake to 2.32 ± 0.319 mmol/min from 0.55 ± 0.033 mmol/min in saline water baseline. The enhanced kinetics reported in this work highlights the potential of engaging L-leucine in the hydrate-based CCS approach.

“…Ghozatloo et al 29 reported that compared with deionized water, using small graphene decreased the induction time by 61.07% while increasing the storage capacity by 12.9%. Liu et al 30 reported that L -Met as a kinetic promoter of CO 2 hydrate is superior to SDS and can be employed as an efficient, reliable, and ecofriendly kinetic promoter for the hydrate-based CO 2 sequestration technology. In this study, graphite carbon nitride (g-C 3 N 4 ) nanoparticles were applied to methane hydrate formation.…”

The effect of graphite carbon nitride (g-C 3 N 4 ) nanoparticledoped sodium dodecyl sulfate (SDS) on the formation of methane hydrate was studied for the first time. In this study, the maximum gas storage capacity is 138 ± 7.35 volumes of methane per volume of methane hydrate only with g-C 3 N 4 as the promoter. However, the whole reaction time was 700 min. To shorten the induction time and speed up the reaction process of methane hydrate formation with g-C 3 N 4 nanoparticles as promotors, anionic surfactant sodium dodecyl sulfate (SDS) was doped on the g-C 3 N 4 nanoparticles to improve the dispersion of the nanoparticles in water and explore the promoting effect of the compound system on methane hydrate formation. Results showed that the compound system can effectively shorten the induction time of methane hydrate formation to 24.33 ± 6.66 min with g-C 3 N 4 −1 mmol/L SDS. Compared with pure SDS, the induction time of the compound system was shortened by 28.23%. At the same time, the gas storage capacity of the hydrate was 151.93 ± 5.63 V/V. Compared with 129.87 ± 16.21 V/V of SDS, the gas storage capacity was increased by 16.98%. Moreover, seven runs of methane hydrate formation−dissociation experiments showed an excellent cycle performance of the compound system.
