📄 Abstract（原文）
The intermittency and volatility of renewable energy sources critically constrain their large‑scale grid integration, positioning underground energy storage as an indispensable solution for the energy transition. This editorial provides a comprehensive overview of major underground energy storage technologies—including salt cavern compressed air energy storage, depleted gas reservoir storage, underground hydrogen storage, geological CO₂ sequestration, and underground thermal energy storage. For each modality, we identify key challenges such as multi‑physics coupling, caprock integrity, geochemical reactivity, and long‑term reservoir stability. We further highlight cross‑cutting frontiers including digital rock physics, artificial intelligence ‑driven characterization, and digital twin technologies. Finally, we issue a formal call for contributions that bridge fundamental mechanisms with field‑scale engineering practice, reaffirming the commitment of Advances in Geo-Energy Research to advancing geo‑energy science for a sustainable future.
