Large‐Scale Hydrogen Storage: Surface and Subsurface Challenges

open access: yesChemBioEng Reviews, Volume 13, Issue 2, April 2026.
This review examines underground hydrogen storage with emphasis on the interaction between surface facilities and subsurface reservoirs. Variable renewable hydrogen requires compression, buffering, and purification before injection, while subsurface processes influence wellhead pressure, temperature, and composition.

Migration of Water and Sand Inrush through the Mining-Induced Caving Zone: Insights from Model Test and Numerical Analysis

open access: yes
Due to the thin bedrock, typical geological characteristics, and the high-intensity underground mining in western China, the water and sand inrush pour into the panels through the broken rock fragmentations in the caving zone, which could result in ...

Investigation of the Dynamic Evolution Mechanism of Bed Separation in Karst Aquifers and Risk Assessment of Water Inrush

open access: yesEnergy Science &Engineering, Volume 14, Issue 4, Page 1864-1880, April 2026.
This study reveals the temporal and spatial evolution law of roof separation under the karst aquifer and the dynamic water inrush mechanism of roof separation. The FAHP–EWM–CRITIC combination weighting method was established to obtain the risk zoning of bed separation water inrush in a karst landform mining area. ABSTRACT Coalfields in northern Guizhou

Inrush Current Measurement in the Water Pumping Station

open access: yesInternational Research Journal of Multidisciplinary Scope
Municipal water pumps use an induction motor with a Fluke 434-II power quality analyzer to measure inrush current. To pump water from the river to the reserve tank, they use two parallel 120 HP motor pumps and two parallel 180 HP motor pumps to deliver water from the reserve tank to overhead tanks distributed across the municipal areas.

Mechanisms of Suspended Microparticle Clogging in Constricted Channels: Insights From a Lattice Boltzmann‐Discrete Element Simulation

open access: yesWater Resources Research, Volume 62, Issue 4, April 2026.
Abstract The migration‐clogging‐sealing process of microparticle suspensions in constricted channels is highly relevant to geotechnical, hydraulic, and environmental engineering. In this study, a coupled lattice Boltzmann‐discrete element method is employed, incorporating dense‐particle corrections into the classical partially saturated method and ...
