While interest in underground gas storage (UGS) of hydrogen (H 2 ) salt caverns is increasing a growing H economy, knowledge the microbial communities inhabiting those hypersaline environments still scarce. High concentrations and limited availability carbon (C) sources cavern reduce growth rates metabolic activities. Growth conditions potentially change once stored caverns. universal electron ...

Abstract Large-scale underground storage of hydrogen gas is expected to play a key role in the energy transition and near future renewable systems. Despite this potential, experience remains limited. This work critically reviews most important elements crucial technology, including properties their significance for subsurface operations, sources historical set state art. The cyclical nature ope...

The paper describes positive and negative aspects of the basic UGS facilities’ impact on the environment using the results of the study of ecologically hazardous factors on the UGS operation areas. On the basis of results of ecological investigations at Russian underground gas storages that have been recently carried out a comprehensive estimation of UGS impact on the environment was given and ...

In this research, gasoline vapours including Benzene, Toluene, Xylene (BTX) and Total Volatile Organic Compounds (TVOCs) emitted from vent pipes of underground storage tanks (USTs) were measured at six gas stations in Tehran. Thereafter, gas station No. 29 was selected as a pilot station and equipped with a vapour control system. The vapours were measured during the summer of 2013 and winter of...

Underground Hydrogen storage (UHS) is a promising technology for safe of large quantities hydrogen, in daily to seasonal cycles depending on the consumption requirements. The development UHS requires anticipating hydrogen behavior prevent any unexpected economic or environmental impact. An open question reactivity underground porous media storages. Indeed, there no consensus effects lack geoche...

Nowadays, underground structures play vital role in developing different countries. Such structures are constructed in many civil activities such as development of road and railways, subways, water, gas and sewage lines, underground subways, nuclear wastes land filling, fuel storage and military installations. With an appropriate drilling method being selected, instabilities created in tunnels ...

Underground gas storage are often subject to external dynamic loads, blast vibrations, and seismic disturbances, since they function as backup areas for the strategic national energy reserve, supply demand dispatch, storage. Currently, research on response characteristics, stability, disturbance control of underground storages under loads is still incomplete great practical importance ensure se...
