How to use compressed air storage in flooded coal mines
Researchers in China developed a new compressed air energy storage system that uses flooded roadways in abandoned coal mines to store compressed air and heat for nighttime power generation. Simulations show the design can achieve 71.5% thermal efficiency, stable performance, and higher energy density at greater depths, with minimal long-term impact from air leakage.

Optimal solar-plus-storage sizing for heavy industry operation
Australian researchers developed a high-resolution energy modeling framework to assess how PV and batteries can supply 24/7 electricity to heavy industries, considering cost, grid interaction, and load flexibility. They found that, while technology cost reductions help, smart grid integration and flexible industrial operations are far more effective in lowering electricity costs and enabling 100% renewable energy use.
