“…and also supported the experimental results (Zhang et al, 2020). The addition of a traditional promoter such as a surfactant or thermodynamic promoter into the water or offering hydrophobic/hydrophilic groups on the carbon surface have proved to be efficient ways of improving gas storage capacity and the hydrate formation rate in porous media (Casco et al, 2017;Cuadrado-Collados et al, 2020;Palodkar and Jana, 2020;Zhang et al, 2020). In the latest research, Cuadrado-Collados et al (2020) reported the promotion effects of various additives, such as the sodium dodecyl sulfate (SDS), leucine, and tetrahydrofuran (THF) in the confined nanospace of the carbon surface, where hydrate nucleation and growth rate were both accelerated significantly.…”

Although hydrate-based technology has been considered as a safe and environmentally friendly approach for gas storage and transportation in recent decades, there are still inherent problems during hydrate production, such as a long induction time, slow formation kinetics, and limited hydrate storage capacity. Attempts to resolve these issues have resulted in the development of various kinetics promoters, among which carbon-based materials have become one of the most attractive owing to their unique promotion effect. Herein, results on promotion by bulk wetted carbon materials in the forms of a packed bed, carbon particles in a suspension, and nano-carbon materials in a nanofluid are collected from the published literature. Meanwhile, the promotion mechanisms and influencing factors of the carbon-based promoters are discussed. The purpose of this mini-review is to summarize recent advances and highlight the prospects and future challenges for the use of carbon-based materials in hydrate production.

“…The concept of “nanoreactors” should theoretically work. Significant work in the synthesis of novel materials has been done by researchers worldwide, notably by Silvestre-Albero and co-workers, ,, for developing efficient gas storage in confined spaces. In addition, it was shown recently that altering the surface wettability of porous materials could strongly enhance the formation of methane hydrates. , Hence, the concept of “nanoreactors” offers a theoretical basic for tailoring porous materials to achieve a better promotion of gas hydrate formation.…”

Hydrogen hydrate is a promising material for safe and potentially cost-effective hydrogen storage. In particular, hydrogen hydrate has potential for applications in large-scale stationary energy storage to dampen the temporal variation of renewable energy, for example, in the form of hydrogen-ready gasfired power plants for generating energy when the renewable power is not available. Preliminary SWOT (strengths, weaknesses, opportunities, threats) analysis indicates that such hydrate-based hydrogen storage (HBHS) has intrinsic competitive edges. However, while the theoretical hydrogen density of the hydrate could reach ∼5 wt %, experiments have not achieved such a high hydrogen storage capacity under practical conditions. This low gravimetric hydrogen density, plus the slow kinetics of hydrogen inclusion in the hydrate, presents an outstanding challenge for commercializing the HBHS. Future research is urged to resolve both the gaps in knowledge and technological barriers for realizing this unconventional technology. Particular future directions include the elucidation of the working mechanism of hydrate promoters, rational designs of new promoters, upscaled experiments and demonstrations, the assessment of long-term stability of hydrogen hydrates, and systematic SWOT analysis. This paper offers an insightful view of the HBHS in low-emission economies.

“…In nucleation, additives may increase or decrease the NIT normally. When the additives delay or hinder nucleation, it means that the NIT is prolonged; ,,− otherwise, the NIT is shortened, ,, and the additives promote nucleation. From the CNT, the variations in NIT may be due to the additives altering the thermodynamic parameters (solid–liquid interface energy γ, Gibbs free energy Δ G , etc.)…”

“…Nucleation is the onset of a first-order phase transition in solution systems that have been supersaturated. It is of enormous importance in various fields, ranging from bioengineering, − materials science, − pharmaceutical engineering, − and geology . Since nucleation often has a profound effect on the properties of products, the following have always been the focus of attention: the research on the nucleation mechanisms, the regulation of nucleation rate, and the buildup of the nucleation mechanistic models.…”

Nucleation is a key step in the crystallization of solution. For regulating and controlling this process, it is thus critical to understand the nucleation mechanism under different circumstances. Note that how additives affect nucleation has not been essentially summarized. This contribution aims to explore the role of additives in theoretical models and practical applications. First, we review the development of nucleation theory: classical nucleation theory (CNT) and nonclassical nucleation theory (non-CNT). Under the framework of CNT, how additives influence the nucleation is expounded through the interactions between species involved in nucleation, along with solid–liquid interfacial energy and pre-exponential factors based on the metastable zone width (MSZW) and nucleation induction time (NIT). In non-CNT, we then discuss the effects of additives on the structural evolution of prenucleated species and competitive properties such as the Gibbs free energy change. Then, we summarize the role of multifarious additives in nucleation. Finally, how additives are adapted to treat some diseases in pathological biomineralization such as lithiasis is summarized. This review has a positive significance for comprehending the roles of additives on the nucleation in a solution milieu.
