The salt cavern storage community, however, has not fully understood the geomechanical behaviors of salt rocks driven by quick operation cycles of H 2 injection-production, which may significantly impact the cost-effective storage-recovery performance. Our...

ABSTRACT: In underground soft rock mines, continuous miner and similar machines are operated by a operator at the cutting face looking for visual cues to control the operation, exposing them to potential dangers. One approach to improve operator safety is to relocate them away from the working...

... successfully used for pure hydrogen storage, since they are much safer and more cost-effective than other underground spaces. However, even a poor design or operated energy storage cavern can result in significant accidents (Liu et al., 2020). Therefore, the main factors in geomechanical design are safety...

Critically stressed natural fractures can yield during operation and decrease the likelihood of flow...

The most prominent impact is induced seismicity, as others have shown, the cause being the increase of pore pressure...
