Underground hydrogen storage (UHS) is a promising technology with which large quantities
of H 2 can potentially be stored in the subsurface safely, economically and efficiently. As …

As key flow properties for coalbed methane production, greenhouse gas reduction through
CO 2 storage in coal and gas drainage to improve mining safety, knowledge of gas diffusion …

The commercial extraction of methane from coal beds is now well established in a number of
countries throughout the world, including the USA, Australia, China, India and Canada …

The diffusion of gas in water-saturated porous media plays a significant role in CO 2
geological sequestration and mine gas prevention and control. However, it is lack of an …

This article reviews the state of research on sorption of gases (CO2, CH4) and water on coal
for primary recovery of coalbed methane (CBM), secondary recovery by an enhancement …

The basic physical parameters and gas desorption characteristics of raw coal and tectonic
coal composite seams in northern China were tested, and the gas diffusion kinetic …

Understanding gas storage and transport mechanisms in shale is crucial for reservoir
evaluation and gas production forecast. The shale matrix has a complex pore structure, with …

In this study, a series of laboratory experiments were performed to firstly analyze the
characteristics of the pore structure in low-rank coal (R o< 0.70%), and then relationships …

This paper discusses the results of an experimental study carried out to study and evaluate
the sorption and diffusion properties of methane in Illinois basin coals. As a first step …

The marine black shale formations on the Upper Yangtze Platform (UYP), South China are
exploration targets for shale gas. Here, we report on the methane sorption capacity of …
