Gas hydrates represent a promising technology for gas storage and transportation. However, their practical application is constrained by the slow formation kinetics of hydrate formation. "Active ice"—synthesized by uniformly dispersing hydrate kinetic promoters into ice powder—has been demonstrated to significantly accelerate gas hydrate formation, thereby offering an effective solution to the kinetic bottleneck in hydrate-based gas storage and transportation. In order to investigate the hydrate formation kinetics of active ice under large-scale application conditions, this study prepared active ice using natural snow as the raw material and employed it in kg-scale hydrate formation experiments. The effects of the concentration of kinetic promoters, reaction pressure, active ice temperature, and packing density on methane hydrate formation kinetics were examined. Additionally, the recycling performance of the active ice were evaluated. The results indicated that active ice derived from natural snow effectively promoted methane hydrate formation. Specifically, when the concentration of the kinetic promoter (sodium dodecyl sulfate, SDS) exceeded 0.25wt%, and the active ice temperature was maintained above 269.15 K, methane hydrate formation was nearly completed within 6 min, achieving a maximum methane uptake of 177.00. The methane uptake increased slightly with rising reaction pressure. Furthermore, by adjusting the packing density of the active ice bed, a maximum apparent gas storage density of 118.90 was attained. In kg-scale hydrate formation and dissociation experiments, the active ice exhibited excellent cycling performance. Collectively, the results of the kg-scale hydrate formation suggested that active ice does not induce significant scale-up effects during hydrate formation, and has essentially met the performance requirements for practical application in hydrate-based gas storage and transportation.
