Geologic energy storage refers to the subsurface storage of energy or energy carriers within geological formations, typically to buffer temporal mismatches between energy supply and demand. It encompasses technologies such as compressed air energy storage in salt caverns or porous reservoirs, hydrogen or synthetic methane storage in depleted hydrocarbon fields and aquifers, and subsurface thermal energy storage in sedimentary basins. Research focuses on reservoir characterization, caprock integrity, multiphase flow, geochemical interactions, and geomechanical responses to cyclic injection and withdrawal, as well as modeling of pressure evolution, leakage risks, and long-term stability to ensure efficient, safe, and reversible utilization of the geological medium as a large-scale energy buffer.
In the North Sea where Denmark once drilled for oil, imported European carbon dioxide will soon be buried under the seabed in a carbon capture and storage (CCS) project nearing completion.

The ground-shaking that an earthquake generates is only a fraction of the total energy that a quake releases. A quake can also generate a flash of heat, along with a domino-like fracturing of underground rocks. But exactly ...
