By integrating gas hydrates as a storage medium, PtX can effectively link renewable energy sources with the gas-based industry, facilitating a smoother transition toward a low-carbon economy. Hydrogen (H₂) storage is a pressing issue due to its low density and the high costs of compression and liquefaction. This study explores the potential of gas hydrate technology for large-scale H₂ storage, particularly in blends with natural gas (H₂–NG). The research delves into the thermodynamic and kinetic properties of H₂–NG hydrates, demonstrating that gas hydrates could offer a viable alternative to traditional storage methods. Experimental and simulation studies indicate that the inclusion of gaseous promoters like methane (CH₄) and propane (C₃H₈) can enhance the H₂ storage capacity within hydrates. The study outlines the formation conditions and stability of various hydrate structures, emphasizing the role of promoters in facilitating H₂ enclathration. Importantly, the study highlights the practical and feasible pathway for the energy transition by integrating H₂ storage into the natural gas infrastructure. The economic analysis underscores the cost-effectiveness of hydrate-based storage compared to conventional methods, considering factors such as energy efficiency and capital expenditure. This study proposes a detailed process for forming, storing, and transporting H₂–NG hydrate pellets, highlighting the potential for integrating this method into existing natural gas infrastructures. The findings suggest that, with further optimization, gas hydrate technology could play a crucial role in the H₂ economy, offering an efficient and sustainable solution for H₂ storage, thus supporting global efforts toward carbon neutrality and clean energy adoption.</p>","PeriodicalId":35,"journal":{"name":"Energy & Fuels","volume":"38 24","pages":"23192–23229 23192–23229"},"PeriodicalIF":5.2,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142850149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hydrogen, hailed as a carbon-neutral energy carrier, offers promising solutions for sustainable energy storage.

Graphene NFs, derived from PAN polymer and reinforced with SnO₂, were synthesized via electrospinning for enhanced hydrogen storage applications. The hydrogen storage capacity of these nanostructures was systematically evaluated using electrochemical analysis across various currents (0.5, 1.0, 1.5, and 2 mA). Our electrochemical findings demonstrate that PAN/GO@SnO₂ NFs, at an optimized current of 1.0 mA, exhibit superior hydrogen storage capabilities, with a capacity of 1111.11 mA h/g compared to 793.65 mA h/g for pure PAN/GO NFs. The substantial improvement in capacitance is attributed to enhanced absorption levels, high-capacity properties, and improved conductivity facilitated by SnO₂ incorporation. Furthermore, morphological analysis via field emission scanning electron microscopy (FESEM) revealed a significant reduction in NF diameter for PAN/GO@SnO₂ NFs compared to PAN/GO NFs, attributed to the improved conductivity and viscosity from SnO₂, resulting in higher surface area and enhanced hydrogen adsorption sites. Fourier transform infrared spectroscopy (FT-IR) confirmed the successful integration of SnO₂ and GO by detecting characteristic peaks, indicating modifications in chemical bonding and enhanced stability.

However, the shale oil potential of older Precambrian sediments remains poorly constrained. Our two newly drilled boreholes reveal shale oil shows in the Mesoproterozoic Hongshuizhuang and Xiamaling shales in the Yanshan Basin, China. In order to further evaluate the shale oil potential, multiple experimental methods were employed, including TOC and thermal maturity analyses, routine and step-by-step Rock-Eval pyrolyses, X-ray diffraction, field emission scanning electron microscopy, low-temperature nitrogen adsorption, and hydrocarbon vapor adsorption. The results show that Hongshuizhuang shale, which is characterized by type II kerogen and low-medium maturity of <i>R</i>₀ = 0.65–0.92%, is a set of good source rocks, while the source rock quality of Xiamaling shale is highly variable. Moreover, the hydrocarbon generation potential of prokaryote-dominated Mesoproterozoic source rocks is comparable to that of eukaryote-dominated Phanerozoic source rocks, implying a favorable factor for shale oil accumulation in Precambrian formations. The main storage space for shale oil in both formations is provided by inorganic pores, in which the adsorbed oil is predominantly retained in micropores to fine mesopores (&lt;15 nm) and free oil mainly stored in mesopores to macropores. Adsorbed oil exists as a multilayer oil film, with its average thickness increasing as a Langmuir adsorption curve with pore size. The evaporative hydrocarbon content of the Hongshuizhuang Formation ranges from 2.53 to 12.53 mg/g and is dominated by adsorbed hydrocarbons (mean 6.01 ± 2.10 mg/g), while the evaporative hydrocarbon content of Xiamaling Formation is much lower, with an average value of 2.4 ± 2.4 mg/g.

In this work, molecular dynamics simulations are employed to investigate the influence of water and salinity on CO₂ adsorption behavior and storage capacity in both organic and clay nanopores. Simulation results show that the presence of water occupies the accessible adsorption space, resulting in a lower storage capacity of CO₂.

An enhancement in pore size can alleviate the CO₂ loss caused by water. The additional NaCl ions result in a further reduction in the adsorption capacity of CO₂. The van der Waals interaction dominates the fluid–surface interaction. A higher interaction energy can be observed in kerogen for CO₂ with reduced mobility, indicating the potential for CO₂ geological storage. Subsequently, the CO₂ storage capacity in the shale pores is evaluated. The kerogen displays a higher storage amount for CO₂ than that for K-illite in any case.
