“…Gautam et al found that adding 0.5 wt % l -leucine to freshwater resulted in CO 2 gas uptake of 0.10 mol CO 2 /mol H 2 O, which was four times higher than the system without a promoter. In addition, l -isoleucine and l -tryptophan have also been proved to be kinetic promoters for improving CO 2 hydrate kinetics. − Thus, in our study, we mainly focus on how low-dose THF (less than 1.0 mol %) can improve the kinetics of CO 2 hydrate formation and aim to examine if there is a synergistic effect when low-dose THF is coupled with a type of amino acid, l -Met, as a KHP for CO 2 hydrate.…”

CO 2 capture and sequestration are broadly recognized as the most effective technology for reducing CO 2 emissions and mitigating global climate change. In this regard, hydrate-based CO 2 sequestration (HBCS) has been proposed as an effective method for long-term safe and stable CO 2 sequestration. It is a promising technology for reducing the concentration of CO 2 in the atmosphere and achieving carbon neutrality. However, one major challenge related to HBCS technology is the lack of understanding of how to improve the formation kinetics of CO 2 hydrate effectively. Herein, in this study, we identified the synergistic promotion effect on CO 2 hydrate formation when a low-dose thermodynamic promoter (tetrahydrofuran, THF) is coupled with an environment-friendly kinetic promoter (L-methionine, L-Met). Based on the kinetic experiments and the morphological observation, 0.6 mol % THF coupled with 0.1 wt %L-Met yields the optimal CO 2 gas uptake. In situ Raman spectra reveal the mechanism of the observed two-step growth behavior at the molecular level, where low-dose THF promotes the initial CO 2 -THF sII hydrate nucleation and growth in the solution and L-Met promotes the subsequent CO 2 sI hydrate growth along the surface of the reactor. Our study unveils the underlying synergistic mechanism when thermodynamic and kinetic promoters are coupled for CO 2 hydrate formation. The results provide guidance for the identification and use of novel bio-friendly thermodynamic and kinetic promoters and are beneficial to a series of sustainable hydrate-based technologies when fast CO 2 formation is required.

“…Other than this, CO 2 injection losses due to reduced permeability during operation and injection point clogging are a major technological barrier . Lack of proper funding mechanisms, CCS regulations, and carbon pricing are some of the societal, governmental, and economic hurdles in adapting HBCS technologies. , The storage in subsea sediments is also associated with preinjection costs such as sedimentary testing (porosity, composition), depth feasibility, and subsea drilling, apart from previously mentioned capture, transportation, and injection costs. The use of artificial-intelligence-based models may solve cost-cognate and logistic issues in subsea sedimentary environments.…”

Subsea sequestration retains a huge potential in terms of the longterm viability of stable CO 2 storage and, therefore, can contribute to global carbon neutrality by addressing global warming challenges. However, macroscopic parameters such as salinity, porosity, sedimentary types, and additives play a vital role in tapping the fullest potential of subsea CO 2 sequestration. This aspect offers a wide range of opportunities for discussion and will open new avenues for future development. Therefore, there is a wide scope for discussions in this area, which will lead to new technological innovations in the future. CO 2 sequestration in subsea sediments in solid hydrate form is discussed in terms of interaction chemistry and macroscopic environmental effects on pore-scale hydrate formation and growth. This Perspective presents insights related to CO 2 hydrate formation and its long-term stability with relevance to porous media, CO 2 -sedimentary interactions, the effect of additives, and possible cost estimates for large-scale CO 2 storage in oceans. Insights into hydrate formation behavior and the effect of physicochemical parameters (interfacial tension, water saturation, organic matter, salinity, and the chemical nature of the sediments) have been additionally outlined. Light is shed on the economics of transportation and injection using cost estimates from the literature along with the challenges and outlook associated with the current technologies. The chemical interactions between CO 2 and hydrate-bearing sediments, additives, and marine environments would aid in understanding hydrate formation in subsea sediments.

“…Adopting the exchange-based production model for production from CH 4 hydrates has its fair share of environmental benefits. The exchange based production approach has been widely researched for long-term sequestration of anthropogenic CO 2 . Also the equilibrium state of the hydrate accumulation acts as a self-limiting factor that involuntarily shuts off the dissociated flow of gas as soon as the stimulating factor (thermal stimulus or depressurization operations) shuts off along with the biogeochemical methane reduction cycle.…”

Natural gas hydrates are unconventional abundant hydrocarbon energy resources that can guarantee energy sustainability with little environmental impact. The solid nature of the resource, distinct thermodynamic characteristics, and accumulations at shallow depths make the existing conventional production techniques unviable. Among all the currently explored production techniques, the hydrate-based carbon capture and sequestration (HBCCS) technique is expected to improve production, proven to be geomechanically safer, and conceptualized to be environmentally friendly. In this carbon-neutral production concept, carbon emissions are effectively sequestered for the long-term. This review presents a comprehensive overview and perspective of the CO 2 exchange-based approach to extract methane (CH 4 ) from naturally occurring gas hydrate reserves, emphasizes its prospect as a suitable alternative according to the current energy demands and climate concerns, establishes its environmental and production challenges, and demonstrates the recent developments. This review focuses on the production aspect and discusses the mechanism of the exchange process, experimental and modeling studies, various in situ production tests using different techniques on multiple sediments, and production challenges associated with the exchange process. The aspects of geomechanics and possibilities of fracturing in hydrate reservoirs are also discussed elaborately. A suitable and effective technique is yet to be established to produce natural gas commercially by addressing the existing challenges like sand production, seafloor stability concerns, marine ecosystem problems, low production rate, uncontrolled dissociation, water production, etc. Although the CO 2 exchange-based method is thermodynamically favorable, rapid crystallization of CO 2 restricts mass transfer and prevents continuous exchange. The exchange process is also influenced by heat, salinity, residual water saturation, exchange gas composition, injection phase, injection pressure, sediment properties, etc. There is a need to study the CO 2 −CH 4 exchange process at a fundamental level and at a larger scale, to understand its intricacies. In tandem with comprehensively discussing the subject, this review has listed the issues that require tenable solutions, which shall be helpful to readers who wish to work on production from CH 4 hydrates using the CO 2 exchange process. Methane hydrates shall be one of the strategic energy sources to meet our growing energy requirements for a sustainable future.
