Performance assessment of a potential underground thermal storage facility: Case study of the closed mine Prosper‐Haniel in the Ruhr coal mining area in Germany

open access: yesDeep Underground Science and Engineering, EarlyView.
This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

Numerical simulation study on the characteristics and propagation attenuation of vibration signals in freezing pipe fracture

open access: yesDeep Underground Science and Engineering, EarlyView.
This research study employs analysis system (ANSYS) fluid–structure interaction simulations to investigate the generation and attenuation of vibration signals resulting from freezing pipe fractures in artificial ground freezing projects. By evaluating key variables—including frozen soil elastic modulus, brine inlet pressure, and external pipe pressure ...

Investigation on the failure evolution characteristics of surrounding rock in deep cross‐fault roadway: Based on physical model test and numerical simulation

open access: yesDeep Underground Science and Engineering, EarlyView.
This study reveals the failure evolution characteristics of deep cross‐fault roadway surrounding rock under excavation support and periodic weighting. Periodic weighting readily induces fault activation, with the spatial distribution of failed rock masses being controlled by the fault strike and dip.

Reusing depleted oil and gas wells for geothermal energy: Feasibility, challenges, and a decision‐making framework for sustainable conversion

open access: yesDeep Underground Science and Engineering, EarlyView.
The graphical abstract presents a structured decision‐support framework for assessing the feasibility of converting depleted oil and gas wells into geothermal energy systems. The left panel illustrates a comprehensive, multi‐stage decision‐making framework progressing from prefeasibility screening and technical–economic analysis to policy alignment ...

Design of a Novel CeW/Fe‐TiO2 Catalyst With High Oxygen Vacancy for Enhancing the Reactivity and SO2 Resistance in Low‐Temperature NH3‐SCR Reaction

open access: yesEcoEnergy, EarlyView.
Fe3+ was introduced into the TiO2 lattice using the hydrothermal method, and low‐valent cations replaced part of Ti4+ to generate oxygen vacancies within the Fe‐Ov‐Ti unit, resulting in CeW/Fe‐TiO2 catalysts with oxygen‐deficient structures. Compared with CeW/TiO2 catalyst, the increase in oxygen vacancy content significantly improved the catalytic ...
