Abstract
In Canada, both natural porosity and excavated cavities are utilized for deep, underground storage. Excavated cavities provide the wider range of acceptable uses and extend underground-storage options beyond the major sedimentary basins. Current dead-storage functions of excavated, underground space include: (1) containment of waste hydrocarbons and mercury compounds in salt caverns, (2) mine storage of rock waste as backfill, and (3) mine disposal of toxic dust from ore milling. The main live-storage functions are: (1) containment of liquefied petroleum gases in salt caverns and (2) underground location of hydro-electric power plants. Potential uses include: (1) submarine storage of hydrocarbons in mine space, (2) fluid storage, related to energy retiming (water, tidal and solar sources); and (3) ultimate disposal of radioactive wastes in salt, granite or serpentinized ultramafic rocks.
