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).

Unveiling spatial heterogeneity in urban underground space development patterns and mechanisms for differentiated planning: A points of interest‐based study of Shanghai

open access: yesDeep Underground Science and Engineering, EarlyView.
This study investigated the spatial patterns and development mechanisms of urban underground space (UUS) in Shanghai using underground points of interest data. It revealed distinct development mechanisms between the main city and suburbs, highlighting the need for differentiated UUS planning and policies to optimize underground space resources ...

Rock mechanical properties under reconstructed deep in situ thermo–hydro–mechanical conditions: Implications for CO₂‐related injection scenarios

open access: yesDeep Underground Science and Engineering, EarlyView.
The graphical abstract illustrates a reconstructed in situ thermo‐hydro‐mechanical (THM) framework in which porosity serves as the central variable linking stress, pore pressure, and temperature to evolving mechanical properties of rocks. Under burial conditions, in situ stress, pore pressure, and temperature jointly govern volumetric strain and ...

Combination of CO 2 ${\text{CO}}_{2}$ storage and geothermal energy production in porous and fractured superhot geothermal systems

open access: yesDeep Underground Science and Engineering, EarlyView.
The graphical abstract depicts the workflow for porous‐ and fractured‐media simulations, where stochastically generated discrete natural fractures are required for the fracture‐media simulation. Abstract CO 2 ${\text{CO}}_{2}$ leakage is one of the main risks and barriers to geologic carbon storage. However, under the high‐temperature and high‐pressure

World's fastest 10 000‐m breakthrough: The XY‐22 well redefines deep‐earth access in the Tarim Basin

open access: yesDeep Underground Science and Engineering, EarlyView.
The Tarim Basin in northwestern China hosts one of the world's deepest petroleum systems, exemplified by the XY‐22 ultra‐deep well (bottom depth: 11 116 m; ~220°C, ~145 MPa). This study integrates tectonic mapping, geological cross‐sections, ultraviolet fluorescence microscopy, and optical photothermal infrared (OPTIR) spectroscopy to characterize ...

Unraveling the Interplay Between Collaborative Governance and Experimentation for Transformative Potential in Circular Water Systems: A Dutch Case Study

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Freshwater availability is a critical climate change challenge in coastal delta regions. This challenge requires a transformative change toward circular water management. While experimentation and collaborative governance are recognized as enablers of transformative change, their interaction remains complex and insufficiently understood ...

Conspiracy Beliefs as a Metacognitive Dimension of Intergroup Attitudes: A Novel Framework for Interventions

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT Apart from their well‐established associations with individual characteristics, experiences of existential threats and either objective or perceived structural circumstances in which people live, conspiracy beliefs are now being increasingly recognised as a reflection of group‐related motivations, identity‐protective motives, prejudice and ...

Learning From and Through Evaluation: An Examination of Practice

open access: yesNew Directions for Evaluation, EarlyView.
ABSTRACT In this article, we provide an analysis across the foregoing practice‐based case exemplars to understand antecedent conditions and influences, learning‐oriented evaluation strategies, estimates of strategy success or potential success, and factors that either enable or hinder the extent to which learning from and through evaluation occurs. The

A Conceptual Framework for Authentic AI‐Enabled Assessment (AAA) in Higher Education

open access: yesFuture in Educational Research, EarlyView.
ABSTRACT Higher education is at a critical juncture as generative artificial intelligence (AI) redefines assessment practices. This article offers a conceptual framework illustrating how authentic AI‐enhanced assessments (AAA) can support the reclamation of higher education's core mission: developing critical thinking, creativity, ethical reasoning ...
