This study introduces a novel class of bifunctional sulfonated surfactants (BFSSs) designed to overcome critical limitations in solidified natural gas (SNG) technology, which stores methane in compact hydrate pellets. Through systematic experimental and molecular dynamics (MD) simulation analyses, the work elucidates the dual promotion mechanism of BFSSs: reducing gas–liquid interfacial tension to facilitate methane entry into the aqueous phase, and promoting local structuring of methane molecules near hydrophobic chains to enhance nucleation. The experimental results demonstrated the outstanding performance of BFSSs at a low concentration of 50 ppm. Among the tested surfactants, BFSS-12 exhibited the best performance in pure water, achieving a methane storage capacity of 160.98 v/v and a water-to-hydrate conversion of 94.30%, highlighting its strong promotion efficiency even at very low dosages. Crucially, BFSSs maintained high efficacy in saline water—a scalable, economical medium—with BFSS-10 achieving 125.82 v/v storage and 69.67% conversion, effectively countering salt inhibition. Furthermore, pelletization studies showed that BFSS-12 imparted high thermal stability, with hydrate pellets retaining 82% of stored gas after 15 days at −5 °C. All BFSS formulations exhibited no persistent foaming during hydrate dissociation, eliminating a major operational hurdle for gas recovery. MD simulations show that BFSSs exhibit chain-length-dependent interfacial aggregation, with chains longer than eight carbons strongly adsorbing at the gas–liquid interface, thereby reducing interfacial tension and enriching local methane concentration. For the energy community, these findings represent a promising advance for methane storage and transport by enabling rapid and high-capacity hydrate formation with minimal chemical input. The compatibility with saline water and foam-free properties directly addresses scalability and economic viability for industrial SNG deployment.

Gas hydrate-based technology represents a promising route for safe, compact, and energy-efficient natural gas storage; however, its industrial deployment is constrained by the need for rapid hydrate formation and long-term stability of hydrate pellets under moderate conditions. This study provides a comprehensive evaluation of methane and associated petroleum gas (APG) hydrate pellet formation, long-term stability, and decomposition behavior using a castor oil-derived biosurfactant (CS) in comparison with the conventional surfactant sodium dodecyl sulfate (SDS). Systematic pressure-dependent experiments (5-9 MPa) revealed that both promoters enhance formation efficiency, yet their effects on pellet morphology and stability differ fundamentally. While SDS ensures rapid kinetics, its foaming-induced porous pellet structure leads to reduced long-term stability and an inverse pressure-stability relationship. In contrast, CS forms denser pellets (0.920 g cm-3) with minimal foaming, resulting in superior self-preservation behavior and improved stability at higher formation pressures. Visual decomposition tests confirmed the operational advantage of CS, exhibiting rapid foam collapse relative to that of persistent SDS-stabilized foams. APG hydrate experiments performed at 6 MPa demonstrated similar conversion (similar to 74%) and storage capacity (similar to 140 v/v) for both promoters; however, CS-based pellets achieved a 36% lower decomposition pressure, indicating significantly enhanced gas retention. These findings establish bio-based CS as a promising promoter for industrial gas storage, offering high efficiency, improved stability, and enhanced operational performance.

The formation of methane hydrates is a promising route for safe and efficient natural gas storage, but slow nucleation kinetics and foaming from surfactant promoters hinder their practical use. To address these challenges, this study evaluates a new class of highly effective kinetic biopromoters synthesized from d-glucono-1,5-lactone and 11 amino acids (GDL+AA). Methane hydrate formation was investigated in high-pressure autoclaves under static and dynamic conditions, complemented by differential scanning calorimetry (DSC), visual observation, pelletization, stability testing, molecular dynamics, and quantum chemical simulations. GDL+AA compounds exhibited a pronounced promoting effect at low concentration (0.05 wt %), initiating hydrate formation in 19-25 min compared with 54 min for sodium dodecyl sulfate (SDS) and 45 min for the unmodified amino acids. Methane uptake reached 0.160 mol/mol, and water-to-hydrate conversion was 88-96% in high-pressure autoclave tests. DSC experiments confirmed higher hydrate formation onset temperature (-9 degrees C for GDL+Met vs SDS: -16 degrees C; Met: -16 degrees C) and higher water to hydrate conversion (99.3% for GDL+Met vs SDS: 70.0%; Met: 28.7%). Visual observations under static conditions corroborated accelerated hydrate growth. Molecular dynamics and quantum-chemical calculations elucidated the mechanism of action of the GDL+AA derivatives. No foaming occurred in the GDL+AA systems during formation or dissociation. Hydrate pellets from GDL+AA showed high density and mechanical strength and high methane retention stability for engineering applications. Chemical modification with gluconic acid significantly enhanced the kinetic performance compared with unmodified amino acids. The synthesis is water-based and mild and uses biocompatible, biodegradable materials, aligning with green chemistry principles. GDL+AA compounds are scalable, efficient, and environmentally sustainable promoters of solidified natural gas.

This study investigates the impact of hydroxyl functionalization on biosurfactants for methane hydrate formation, emphasizing their potential in sustainable gas storage. Sodium oleate (SO) and hydroxylated sodium oleate (HSO), derived from oleic and ricinoleic acids, respectively, were synthesized and evaluated as eco-friendly promoters. HSO outperformed SO and conventional surfactants, such as sodium dodecyl sulfate (SDS), particularly at low concentrations (50 ppm). Methane hydrate formation with HSO achieved an impressive conversion efficiency of 94.95 % at 50 ppm, surpassing SDS. HSO significantly enhanced storage capacity up to 161.86 v/v, exceeding the 157.90 v/v capacity of SDS. The optimized balance of hydrophilic and hydrophobic properties in HSO enhanced gas-water interactions, enabling rapid hydrate crystallization and stabilization. Furthermore, HSO exhibited superior performance in saline environments, achieving higher methane consumption and water-to-hydrate conversion rates compared to SO and SDS. This highlights the advantages of using seawater as a medium for methane hydrate formation, as it reduces operational costs and enhances sustainability. Methane hydrate pellet formation experiments revealed that HSO led to a faster formation rate and higher conversion degree. The resulting pellets were more stable and exhibited greater methane storage capacity. In long-term stability tests, HSO-based pellets retained more methane than SO-based pellets after 15 days at -5 °C. Additionally, HSO demonstrated excellent thermal stability in both pure and saline water, remaining structurally intact at elevated temperatures. These findings highlight the potential of molecularly tailored biosurfactants, such as HSO, as green and efficient alternatives to conventional surfactants for methane storage and transportation. This advancement aligns with global sustainability goals and supports the broader adoption of hydrate-based solidified methane technology.

This study addresses the challenges of methane hydrate storage by developing novel double-chain surfactants (DCSs) to enhance the rapid production of high-density methane hydrate pellets. The analysis of micellization behavior revealed that longer alkyl chains in DCSs form smaller and more uniform micelles, significantly impacting their performance as hydrate promoters. Among the tested DCSs, DCS-12 at 500 ppm showed the highest storage capacity (168.71 v/v) and almost complete conversion (99.92 %), maximizing water's potential to form hydrates. DCSs demonstrated high conversion efficiency (over 88 %) at concentrations as low as 5 ppm, suggesting strong potential for cost-effective and scalable applications. The methane hydrate pellets formed with DCS-12 were dense and stable, particularly at 500 ppm, with minimal methane release over a week. This enhances the ease of handling, storage, and transportation of methane in solid form, making it more viable for industrial applications. The differential scanning calorimetry thermograms in the presence of DCSs demonstrated that alkyl chain length significantly influenced their promotion activity, with shorter alkyl chains providing higher efficacy. This increased performance is attributed to enhanced molecular mobility and reduced steric hindrance, allowing for more efficient interactions during hydrate formation. Additionally, DCS-12 exhibited no stable foam formation during gas recovery, enhancing recovery efficiency. The DCSs also performed well in saline conditions, a key economically advantageous for hydrate-based methane storage. By accelerating hydrate formation, enabling high conversion, and forming compact pellets, DCS-12 offers a promising solution for improving methane storage and transport. Its effectiveness in both pure and saline environments, coupled with low required concentrations, makes it suitable for scaling up solidified natural gas technology.

Solidified natural gas (SNG) is a perspective method for transportation and storing hydrocarbon gases under mild conditions. The aim of this work is to synthesize new compounds based on several amino acids (leucine, methionine, phenylalanine, norleucine, aspartic acid, valine, glutamic acid, norvaline, proline, threonine, alanine, 6-aminohexanoic acid, cysteic acid) with nitrilotriacetic acid (NTA + AA) to improve the efficiency of methane transition from gas phase into hydrate form and compare them with to pure amino acids and sodium dodecyl sulfate (SDS) as well known gas hydrate promoters. According to the results of high-pressure autoclave experiments, 7 NTA + AA samples out of 13 increase methane uptake and water to hydrate conversion better than SDS, which is a well-known effective promoter of hydrate formation, and 12 NTA + AA samples out of 13 have shorter induction times than SDS. In addition, visual observations showed that all the novel promoters synthesized from amino acids and nitrilotriacetic acid do not cause foaming throughout the process of methane hydrate dissociation, which improves the performance of this type of promoter in comparison with SDS. The efficiency of kinetic hydrate promoters at 0.05 wt% concentration by maximum mole consumption of methane decreased in the range of samples: NTA + Phenylalanine > NTA + Glutamic acid > NTA + Leucine > NTA + Norleucine > NTA + Aspartic acid > NTA + Alanine > NTA + Valine > NTA + Norvaline > SDS > NTA + Proline > NTA + Methionine > NTA + Threonine > NTA + Cysteic acid > NTA + 6-aminohexanoic acid. NTA + Phe (nitrilotriacetic acid + phenylalanine) was able to achieve 98.2 % water to hydrate conversion (0.164 mole gas/mole water) at 0.05 wt% concentration, and its induction time was independent of concentration and approximately equal to 30 min, which was about half that of SDS and pure phenylalanine. Thus NTA + Phe can be considered as one of the best promoters of methane gas hydrate formation, which can be used at low concentrations. Modification of amino acids with nitrilotriacetic acid was shown to significantly improve the efficiency of the compounds as kinetic promoters of hydrate formation, both in terms of induction time and methane uptake, compared to pure amino acids, which makes it possible to create more effective eco-friendly non-foaming promoters of methane hydrate formation used at low concentrations.

The development of efficient, non-foaming promoters is essential for advancing the industrial applications of solidified gas hydrates in carbon capture, natural gas storage, and transportation. In this study, a novel surfactant, containing sulfonate, amide, and carboxyl groups (SSAC), was introduced as a promoter for methane hydrate formation. SSAC was synthesized by integrating the chemistries of amino acids and sodium dodecyl sulfate (SDS), distinguishing it from existing promoters. High-pressure autoclave experiments demonstrated that SSAC significantly enhanced the kinetics of methane hydrate formation, at a low concentration of 5 ppm, achieving a maximum water-to-hydrate conversion of 85.2 %, equivalent to a storage capacity of 163.5 v/v in deionized water. Increasing the SSAC concentration to 500 ppm resulted in an impressive conversion rate of 94.6 % and a storage capacity of 181.6 v/v. Methane recovery was accomplished without foaming within 15 min during hydrate dissociation at room temperature, addressing a critical challenge in current hydrate-based storage systems. Molecular dynamics simulations further revealed that SSAC molecules act as collectors for methane molecules in solution, thereby enhancing the rate of hydrate growth and increasing the number of hydrate cavities. Notably, SSAC exhibited a biodegradation level of 41 % after 28 days, indicating its potential for natural degradation and environmental compatibility. This combination of low concentration efficiency, foam-free formation, environmental sustainability, and enhanced methane collection is unprecedented in the current literature, highlighting the innovative nature of this work. These findings suggest that the integration of amino acid structures with anionic surfactants offers a promising strategy for designing effective promoters, with significant implications for energy storage, seawater desalination, and carbon capture technologies.

Gas hydrate plugging is a major issue in oil and gas production, transportation, and processing. These blockages impede fluid flow in pipelines, reducing efficiency and production rates. Moreover, they can result in uncontrolled hydrocarbon release, posing safety and environmental risks. Recent studies have focused on carbohydrate polymers and their derivatives as green gas hydrate inhibitors. However, their impact on hydrate agglomeration remains underexplored. This study synthesized and evaluated chitosan biguanidine (CSG) for its dual-inhibition effects on methane hydrate formation and agglomeration. Experimental results showed that CSG increased the induction time from 2 h in pure water to over 4.5 h and reduced the maximum gas uptake from 55 % to 42 %. In decane-water solutions, the induction time extended to 7 h with CSG addition, leading to a decrease in maximum gas uptake from 32.7 % to 9.3 %. Furthermore, CSG significantly mitigated torque fluctuations, indicating a reduction in hydrate particle agglomeration and a more stable fluid flow. An optimal concentration of 1 wt% CSG was found effective in preventing hydrate agglomeration and maintaining a stable, low torque value in both water and decane-water solutions. Simulation results revealed that CSG prevented hydrate particle aggregation by forming a surface barrier on hydrates and incorporating into hydrate cavities. Toxicity studies indicated that CSG exhibits low toxicity towards skin and lung cells, making it a safe alternative to conventional inhibitors. This study present novel insights into the inhibition mechanism of gas hydrate inhibitors and pave the way for the development of more effective and environmentally friendly solutions for managing gas hydrate formation and agglomeration in oil and gas systems.

Gas hydrate deposition is a complex issue with significant implications for the oil and gas industry. The formation of solid gas hydrates in the hydrocarbon transportation pipelines leads to production disruptions and potentially even complete blockages, resulting in huge financial losses and operational difficulties. For over two decades, kinetic gas hydrate inhibitors have played a crucial role in preventing the formation of gas hydrates within the flow lines of oil and gas production. They directly influence the kinetics of hydrate formation, hindering nucleation and slowing down crystal growth. In this study, five new waterborne polyurethanes (WPUs) with varying degrees of hydrophobicity as inhibitors for cubic structure II gas hydrates were synthesized and tested using rocking cells and differential scanning calorimetry. The synthesis of WPUs involved the reaction between dialkylamines (diethyl, dipropyl, dibutyl, dibenzyl, and dioctyl) and glycidol under mild conditions. All WPUs effectively prevented gas hydrate formation, and a correlation between their efficiency and the alkyl chain length was observed. The inhibitory efficacy of WPUs increased with the extension of the alkyl chain from ethyl to butyl. WPU-DBuA, featuring butyl groups, exhibited the highest inhibition activity. It provided a subcooling temperature of 12.9 and 15.6 degrees C at 0.25 and 0.5 wt%, respectively, surpassing commercial samples, such as Luvicap EG and Luvicap 55 W. Additionally, the solutions containing 1 and 2 wt% of WPU-DBu exhibited maximum subcooling temperatures of 16.2 degrees C and 16.7 degrees C, respectively, which correspond to a 79.7 % and 85.4 % reduction in gas uptake during hydrate growth compared to pure water. However, the inhibitory power of WPUs diminished with larger alkyl (dioctyl) or aromatic groups (dibenzyl), indicating that dibutyl represents the optimal alkyl length for achieving maximum performance. Moreover, WPUs demonstrated a reduction in hydrate conversion under static conditions, signifying their efficiency when the flow is stopped. WPUs lowered the onset temperature of hydrate formation from 3 degrees C in pure water to temperatures below -12 degrees C. Thus, WPUs demonstrated a remarkable ability to prevent the formation of structure II gas hydrates, even under high subcooling conditions. Additionally, WPU-DBuA exhibits a considerable degree of biodegradability, as evidenced by its biodegradation level of 44 %, suggesting that it has the potential to break down more easily in the environment compared to Luvicap 55 W. This research contributes to a deeper understanding of the structure - property relationships of KHIs. This can facilitate the development of more effective and eco-friendly inhibitors, which helps address environmental concerns associated with using KHIs in the oil and gas industry.

In this work, we studied new citric acid derivatives of some amino acids, which improve the formation kinetics of methane hydrate at low concentrations. These compounds hold potential as efficient promoters of hydrate formation with the advantage that they do not foam upon release of the gas from the hydrates. The modification of the amino acids by citric acid enhances their efficiency as kinetic promoters of methane hydrate formation relative to the unmodified amino acids. This leads to shortening of the induction time and time to achieve maximal conversion of water to hydrate as well as to enhancing the methane uptake. The amide of norleucine and citric acid enhances the conversion of water to hydrate relative to the unmodified amino acid. For 0.05 mass

This study investigated the formation of associated petroleum gas (APG) hydrate from frozen solutions of promoterфs (sodium dodecyl sulfate and trisulfonated castor oil) under static conditions. The experiment utilized differential scanning calorimetry to analyze phase changes, such as ice crystallization, hydrate formation, and joint ice melting and hydrate formation. The visualization of the hydrate formation process helped identify factors that influence APG hydrates’ growth under the given conditions. The study concluded that the type and presence of promoters significantly affect the growth rate of hydrates, while the preparation protocol has a greater impact on the reproducibility of the process.

CO2 hydrate formation kinetics are relatively slow, hindering large-scale implementation for carbon capture and storage. Amino acids have been widely investigated as green promoters for CO2 hydrate formation due to their potential in the CO2 uptake capacity. However, there is still a limited number of studies focusing on the application of biosurfactants for CO2 hydrate formation. In this study, four biodegradable surfactants (BSs), derived from castor oil, were investigated as efficient promoters for CO2 hydrate formation. BSs provided the highest promotion efficiency, enhancing CO2 uptake by 10 times and achieving a 50.19% conversion degree compared to 6.45% in pure water. An important characteristic of BSs is their high biodegradability, as demonstrated by a BOD/COD ratio of 52.2% after 28 days. The combination of promotion power, non-foaming properties, and biodegradability makes BSs unique candidates for addressing the challenges associated with CO2 capture and storage using hydrate-based sequestration strategies.

Abstract Due to the discovery of new giant fields, the Russian Federation is actively shifting oil and gas production to northern regions and the Arctic shelf. However, harsh operating conditions, low temperatures, special environmental requirements, and limited infrastructure require new approaches to the full-scale development of the fields. Using gas hydrates as an alternative technology for storing and transporting natural/associated gases is becoming increasingly relevant. This technology has many advantages, such as environmental safety, relatively low temperatures and pressures for hydrate formation and storage, and high gas content in the hydrate form. Special attention is paid to developing efficient methods to produce the hydrates, on which the feasibility of the entire technological process depends. Several highly efficient reagents to accelerate hydrate formation were designed and successfully implemented in scientific and technical projects devoted to solidified natural gas technology. The hydrate issue also arises due to the need to create a controlled flow of hydrate particles in oil.

The processes of formation (and decomposition) of methane hydrate from water adsorbed in the pores of spherical granules of mesoporous alumina (Al 2 O 3 ) have been investigated using the low-field NMR spin - spin relaxation time (T 2 ) and DSC methods. Analysis of the obtained data showed that changes observed in the relaxation time spectra represent a strong case in favor of the model envisaging hydrate growth in pore spaces without conspicuous water transfer through the volume content of the sample with mesoporous structure. As the supercooling strength of the liquid phase enhances, the size of the pores in which hydrate formation takes place decreases. At this, the size of the hydrate particles previously formed in larger pores tends to increase. Hydrate nucleation was shown to be followed by intensive and rapid hydrate formation in some parts of the alumina granules in the sample. The " skipping " mechanism of hydrate formation between granules remains unclear.

This paper introduces a laboratory setup designed to produce gas hydrate under static conditions and to compress hydrate pellets directly within the reactor. The setup is intended to facilitate development of effective methods for obtaining and storing gas hydrates. The paper discusses the design specifics of the setup, outlines the sequence of operations for producing methane hydrate and granules from it, and provides examples of experimental data related to accelerated production and compression of methane hydrate from a kinetic promoter solution.

The study of hydrate formation in porous media (quartz sand) in the presence of promoters is a key point both for the fundamental understanding of natural gas hydrate behavior and for practical applications in transportation and storage processes. In this work, the effect of several kinetic promoters including sodium dodecyl sulfate (SDS), carboxyl-sulfonated surfactants based on sulfosuccinates of dodecanol and butanol (CSS12 and CSS4), and EDTA amide with leucine amino acid (ACD5) with different surface activity on the formation of methane and a model methane-propane mixture hydrates in a porous media (quartz sand) was evaluated under static conditions using differential scanning calorimetry (DSC). The difference between reagents in the dependence of conversion on water saturation for different hydrate formers was found. For methane hydrate in the case of water and additives with weak surface properties, an increase in conversion with decreasing water saturation was observed, while for surfactants SDS and CSS12, on the contrary, the highest conversion was achieved at the highest water saturation. Thus, when using porous media for surfactants, there is generally a small increase in conversion relative to a static system without porous media or a dynamic system, while for non-surfactants, porous media helps to significantly increase conversion under static conditions. In the case of methane-propane hydrate in all systems, the conversion increased with decreasing water content. The static and dynamic studies showed that only the use of the porous medium allows to achieve high conversion. The highest conversion of water to hydrate in porous media equal to 94 % for methane (at high water saturation) and 92 % for the gas mixture (at a low water saturation) were achieved. Kinetic calculations using the Avrami model also showed a difference between reagents with different surface activities. The results obtained with DSC were visualized using a high-pressure cell with sapphire windows. It was shown that different patterns of hydrate growth in the presence of additives under static conditions can affect the conversion: in the case of methane for surfactants, intense hydrate growth on the cell walls was observed, whereas in other cases, this effect was less pronounced.

Gas hydrates offer a promising solution for clean and low-carbon energy storage and the transportation of natural gas. However, their slow formation kinetics and dissociation-induced foaming hinder their practical application. This study investigates a novel branched sulfonated promoter (BSP) to address these challenges. The effectiveness of BSP in promoting methane hydrate formation was evaluated by measuring the conversion degree, methane consumption, storage capacity, hydrate growth rate, and reaction rate constant. Molecular dynamics (MD) simulations provided insights into BSP's interaction with methane and water molecules, its selfaggregation, adsorption, and its role in hydrate cage formation. BSP demonstrated comparable performance to SDS in accelerating methane hydrate formation. At a concentration of 500 ppm, BSP achieved a water-to-hydrate conversion rate of 89.54 %, methane consumption of 432.16 mmol, and a storage capacity of 165.1 v/v after 450 min. BSP effectively suppressed foam formation during methane hydrate dissociation, and all the hydrates melted within 15 min. Moreover, BSP promotes the formation of dense and solid hydrates, unlike SDS, which favors hydrate growth on reactor walls. MD simulations revealed that BSP molecules do not form micelles but interact with water molecules through their hydrophilic chains, facilitating methane accumulation around their hydrophobic tails. This behavior promotes methane aggregation and hydrate formation. BSP surpasses SDS in terms of foam-free dissociation, making it a promising candidate for practical hydrate-based energy storage and transportation technologies. The combined experimental and computational approach provides valuable insights into the mechanisms underlying BSP's promotional effect, challenging the long-held belief that long alkyl chains are essential for hydrate promotion. This paves the way for further development of effective and environmentally friendly hydrate promoters.

To address the challenges associated with gas hydrate formation in deepwater environments, two novel waterborne polyurethanes were developed using etidronic acid (EA-WPU) and citric acid (CA-WPU) as kinetic hydrate inhibitors. EA-WPU exhibited superior inhibition, completely preventing sII hydrate formation at a concentration of 0.5 wt %. CA-WPU also showed strong performance, with subcooling temperature (Delta T) values of 13.16 and 11.62 degrees C at concentrations of 0.5 and 0.25 wt %, respectively. These polymers have demonstrated high efficiency in inhibiting sII gas hydrate formation, even at a low concentration of (0.05 wt %). The inhibition performance against sI hydrates varied, with Luvicap EG and CA-WPU demonstrating the strongest inhibitory effects. At 0.5 wt %, CA-WPU exhibited a Delta T value of 6.05 degrees C, comparable to that of Luvicap EG. This study suggests that the specific functional groups present in the end-cap structure of WPUs directly influence their ability to inhibit sI and sII hydrates. Carboxylic acid and phosphonate groups appear to be more effective for sI and sII hydrates, respectively. Moreover, field-specific assessments demonstrated that EA-WPU at 0.25 wt % achieved a Delta T of 15.5 degrees C, surpassing the required Delta T of 12 degrees C to prevent hydrate formation at 280 bar and 15 degrees C. This allowed for a 90-fold reduction in inhibitor consumption compared to 23 wt % methanol solution. Additionally, the inhibitor solutions remained transparent and exhibited no clouding up to 70 degrees C at concentrations of 2 and 1 wt %, respectively. Although clouding occurred at higher concentrations and temperatures, both solutions remained stable without deposition even at a concentration of 8 wt % and a temperature of 70 degrees C. These results highlight the excellent thermal stability of EA-WPU and CA-WPU, making them suitable for high-temperature injection up to 2 wt %. Good inhibition performance at low concentrations and high thermal stability of WPUs make them promising candidates for widespread application in gas hydrate management, offering significant operational cost savings and reduced environmental impact.

The use of natural gas as an energy source is increasing significantly due to its low greenhouse gas emissions. However, the common methods of natural gas storage and transportation, such as liquefied or compressed natural gas, are limited in their applications because they require extreme conditions. Gas hydrate technology can be a promising alternative to conventional approaches, as artificially synthesized hydrates provide an economical, environmentally friendly, and safe medium to store energy. Nevertheless, the low rate of hydrate formation is a critical problem that hinders the industrial application of this technology. Therefore, chemical promoters are being developed to accelerate the kinetics of gas hydrate formation. In this paper, the effect of new sodium sulfosuccinate compounds, synthesized based on glycerol and pentaerythritol, on methane hydrate formation was studied. Experiments under dynamic conditions using high-pressure autoclaves demonstrated that the conversion of water-to-hydrate forms increased from 62 ± 5% in pure water to 86 ± 4% for the best promoter at concentration 500 ppm. In addition, the rate of hydrate formation increases 2–4 times for different concentrations. Moreover, none of the synthesized reagents formed foam, compared to sodium dodecyl sulfate, in which the foam rate was 3.7 ± 0.2. The obtained reagents showed good promotional properties and did not form foam, which makes them promising promoters for gas hydrate technology.
