Deep 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).

EcoEnergy, EarlyView.A bimetallic NiAg alloy is assembled on the surface of Zn3In2S6 to construct a NiAg‐Zn3In2S6 composite using a chemical reduction method. By adjusting the different alloy ratios, the hydrogen evolution activity of the optimum Ni0.25Ag0.75‐Zn3In2S6 photocatalyst achieves 21.32 mmol·g−1·h−1. ABSTRACT A bimetallic NiAg alloy is assembled on the surface of
