For a good management and precise tracks of hydrogen quantities stored in salt caverns, this paper presents study on transport rock during cycling. It provides novel mathematical–numerical model that couples the cavern thermodynamics with mechanisms saturated fully coupled thermo–hydraulic framework. Both two–phase Darcian percolation Fickian diffusion are used to account for migration intersti...

The underground powerhouse of a hydropower station, in the form cavern group, is generally characterized by large scale and complicated spatial structure. During construction phase, extensive excavation limited space may cause multi-cavern effect between adjacent caverns thus lead to deformation failure surrounding rock mass, which undoubtedly compromises stability safety. This paper takes drai...

Anthropogenic effects on climate can be mitigated through various measures, among them being CO2 sequestration in geological media. Geological sinks for CO2 do not need any major new technological development; the technology exists and has been applied for other uses. The challenge is rather to identify the most appropriate methods and sites for long-term sequestration. There are several potent...

Evaluating the possibility to store CO 2 in salt mines is made complex because of lack necessary data and different mechanisms that act on time scales. This analysis can be using traditional methods geographical survey, lab experiments digital simulations. Storing needs done a stable geological area. The cavity must thoroughly analysed for dimensions, depth, permeability porosity. Based studies...

The presence of a high concentration Cl− in saltwater will erode the structure and facilities, reducing stability service life underground oil storage cavern. In order to reduce risk seawater intrusion, this paper studies prevention technology intrusion based on case study coastal large-span A refined three-dimensional hydrogeological model that comprehensively considers permeability coefficien...
