Integrating Copper Slag Into Thermally Active Building Foundations: A Pathway to Sustainable Underground Energy Storage Systems

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Underground thermal energy storage (UTES) integrated with building foundations is an emerging pathway to decarbonize space conditioning by shifting low‐carbon heat across seasons. This review evaluates copper slag, a high‐density, thermally stable byproduct of smelting, as a dual‐function medium for thermally active foundations.

Hydrogen Direct Reduction: History and Pathways for Cost Reduction

cScience, Volume 1, Issue 1, December 2025.
ABSTRACT The steel industry, a critical pillar of global economic development, is highly energy‐intensive, accounting for approximately 7%–9% of global energy‐related CO2 emissions. The transition from traditional carbon‐intensive metallurgy to hydrogen‐based metallurgy represents a pivotal pathway for the green and sustainable development of the steel

Hydrogen sulfide in underground hydrogen storage sites: Implication of thermochemical sulfate reduction

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 709-724, December 2025.
A one‐dimensional diffusion‐based mass transport model was built using PHREEQC to highlight the potential challenges posed by thermochemical sulfate reduction (TSR) in depleted gas fields. The results obtained indicated that the presence of iron minerals (pyrite and hematite) is crucial for H2S generation through TSR reactions.
