Microorganisms influence the chemical and physical properties of subsurface environments and thus represent an important control on the fate and environmental impact of CO2 that leaks into aquifers from deep storage reservoirs. How leakage will influence microbial populations over long time scales is largely unknown. This study uses natural analog sites to investigate the long-term impact of CO...

The injection of carbon dioxide (CO2) in deep, unmineable coalbeds is a very attractive option for geologic CO2 storage: the CO2 is stored and at the same time the recovery of coalbed methane (CBM) is enhanced. The revenue of methane (CH4) production can offset the expenditures of the storage operation. Coalbeds form complex gas reservoirs characterized by their dual porosity: they contain both...

Methane hydrates (MHs) are present in large amounts in the ocean floor and permafrost regions. Methane and hydrogen hydrates are being studied as future energy resources and energy storage media. To develop a method for gas production from natural MH-bearing sediments and hydrate-based technologies, it is imperative to understand the thermal properties of gas hydrates. The thermal properties' m...

van der Waals density functional theory (vdW-DFT) and semiempirical grand canonical Monte Carlo (GCMC) calculations are used to predict the thermodynamics and methane storage capacity of 18 metal-substituted variants of the metal−organic framework (MOF) M-DOBDC (DOBDC = 2,5-oxidobenzene-1,4dicarboxylate). Methane adsorption enthalpies (ΔH) on the benchmark Mgand NiDOBDC systems were calculated ...

Porous materials such as metal-organic frameworks (MOFs) with high theoretical volumetric gas uptake capacity are promising for storage and separation, but the structuring practical applications is challenging. Herein, we report a general feasible strategy to combine electrospinning phase conversion method decorate polyacrylonitrile nanofibers (PAN NFs) Cu-MOF (HKUST-1). The based on combinatio...
