Hydrogen (H 2) is currently considered a clean fuel to decrease anthropogenic greenhouse
gas emissions and will play a vital role in climate change mitigation. Nevertheless, one of …

Geological formations are suitable locations for CO 2 sequestration, and among them, coals
are excellent targets because of their nanoporous structure, which leads to a high gas …

Hypothesis Hydrogen geo-storage is considered as an option for large scale hydrogen
storage in a full-scale hydrogen economy. Among different types of subsurface formations …

Coal bed methane (CBM) is a primary clean energy source found in coal seams. The
recovery ratio of CBM is very low, especially with ground extraction, due to the strong …

To study the pore structure characteristics of middle-high rank coals (MHRC), five different
kinds of coal samples from northern China were selected and pulverized, and the pore …

Coal pores not only serve as the storage space for coalbed methane but also provide
channels for gas migration. The accurate characterization of coal pore structures is of …

Coalbed methane (CBM) is an unconventional natural gas that possesses significant
impacts on energy supply, mining safety, and environmental conservation. CBM is primarily …

Methane is primarily stored in coal matrix pores and pore size distribution has an important
effect on gas adsorption/desorption. Investigation of the relationship between pore size …

The microstructure of coal, such as matrix morphology, pore structure and carbon structure,
is of great significance to the resource enrichment in coal and the study of graphitization. In …

Pores in coal have the characteristic of double peaks, and the bidisperse diffusion model is
an effective method to describe the diffusion behavior in coal. At present, the traditional …
