A novel technological conception of integrated large‐scale CO2 storage, water recovery, geothermal extraction, hydrogen production, and energy storage

open access: yesDeep Underground Science and Engineering, EarlyView.
A holistic utilization system that integrates large‐scale CO2 storage, water recovery, heat extraction, hydrogen production, and energy storage is presented. The whole system can be further divided into upstream industries (CO2‐enhanced water recovery module), midstream industries (green‐hydrogen production module), and downstream industries (energy ...

A rock brittleness index based on the postpeak energy release rate and damage surface characteristics for brittle hard rock

open access: yesDeep Underground Science and Engineering, EarlyView.
This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.

Coupled THM analysis of long-term anisotropic convergence in the full-scale micro tunnel excavated in the Callovo-Oxfordian argillite [PDF]

open access: yes, 2019
The main purpose of this paper is to analyse the convergence measurements of the ALC1604 in situ heating test carried out in the Callovo-Oxfordian claystone formation (COx) in the Meuse/Haute-Marne underground research laboratory (MHM URL).

Numerical and experimental study on P‐wave propagation across a rock joint with different orientations

open access: yesDeep Underground Science and Engineering, EarlyView.
Joint orientation significantly affects P‐wave velocity, with the highest velocity at zero‐degree angles, decreasing to 30° as the angle increases. The velocity increases slightly from 30 to 45 degrees but sharply decreases from 45 to 90 degrees. Abstract Determination of the required parameters in different science contexts using the ultrasonic wave ...

Elastic and elastoplastic analysis of surrounding rock in CAES chambers considering excavation‐induced centripetal exponential reduction in mechanical properties

open access: yesDeep Underground Science and Engineering, EarlyView.
This study presents an analytical framework for evaluating stress distribution in compressed air energy storage (CAES) chambers, incorporating excavation‐induced damage. Key findings highlight the impact of excavation disturbed zones (EDZs) on stress patterns and bearing capacity, offering design strategies to optimize chamber stability and improve ...
