Ensuring the stability and integrity of underground gas storage salt caverns is a very complicated subject due to the non-linear and time-dependent behavior of rock salts under complicated thermal and mechanical loading conditions. For this reason, pressure and temperature fluctuations in the caverns and their surrounding strata must be integrated into the analysis and the numerical tools that ...

Underground caverns in rock salt deposits are the most secure disposal method and a type of gas-storing facility. Gas storage plays a vital role in ensuring that a strategic relationship is secured between an established energy infrastructure provider and a midstream energy company. The Fischells Brook area is a pillow-shaped body of salts located in the St. George's Bay area of southwest Newfo...

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...

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...

In the process of building a new power system with energy sources as mainstay, wind and photovoltaic enter multiplication stage randomness uncertainty, foundation support role large-scale long-time storage is highlighted. Considering advantages hydrogen in large-scale, cross-seasonal cross-regional aspects, necessity, feasibility economy participation under are discussed. Firstly, supply demand...

Rectangular caverns are increasingly used in underground engineering projects, the failure mechanism of rectangular cavern wall rock is significantly different as a result of the cross-sectional shape and variations in wall stress distributions. However, the conventional computational method always results in a long-winded computational process and multiple displacement solutions of internal re...
