Large‐Scale Hydrogen Storage: Surface and Subsurface Challenges

ChemBioEng 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.

40 Promoting healthy lifestyles in an open pit coal mine [PDF]

Mining Occupational Safety and Health, 2018
Introduction Open pit coal mines face different occupational risks, however little attention has been placed on the importance of promoting in the labour and social sphere of workers healthy lifestyles. In an open coal mine in Colombia and with the goal to prevent general and occupational diseases and overall to improve quality of life, was developed ...

Regional Personality Variation in Sweden: Trait Clusters, Links to Health and Well‐Being, and Historical Context

Scandinavian Journal of Psychology, Volume 67, Issue 2, Page 439-472, April 2026.
ABSTRACT Personality traits (e.g., the Big Five) shape human behavior, decision‐making, and life outcomes. Evidence from various countries suggests that these traits are not randomly distributed but follow systematic regional patterns, fueling interest in their geographical variation.

Applying Karst Hydrology Concepts to Anthropogenic Subsurface Systems and Mine Water Management

Hydrological Processes, Volume 40, Issue 3, March 2026.
Due to the pronounced similarities between natural karst systems and mine workings, we consider mine workings as man‐made karst and present the concept of ‘anthropogenic karst’. ABSTRACT Mine water management is a permanent challenge in post‐mining areas where drainage adits play a crucial role for the regulation of water levels within partially ...
