High-Pressure Isotherms of Gas Hydrates with Nanoporous Materials: Investigating Storage Capacity and Formation Dynamics

Gas hydrates form when water and gases, such as CO₂ or CH₄, combine under high-pressure, low-temperature conditions, creating an ice-like crystalline structure. These hydrates offer a safer storage alternative for explosive gases like natural gas or H₂, as they do not explode when unstable. Enhancing the water-gas interface area using nano-porous materials, such as metal-organic frameworks or activated carbon, can improve gas storage in gas hydrate crystals. Surface properties, including hydrophobicity, and pore characteristics, such as size and geometry, also play essential roles in controlling kinetics, overall storage, and thermodynamics of the formation process.

In this research, we aim to investigate the gas storage capacity in a hybrid system involving gas hydrate formation with nanoporous materials under varying water saturation levels. We specifically focus on understanding the impact of hydrophobicity and surface chemistry on the formation process. To examine the gas storage in this hybrid system, a series of high-pressure reactor experiments are conducted to generate gas isotherms at low temperatures (1-2°C) under different water loading levels. These results are compared with those from a bulk water system to confirm the synergistic effect of nano-porous materials.

X-ray diffraction (XRD) data is collected to ensure material stability during the formation process under various conditions. Key findings will be presented and discussed during the poster session for visitor
