<p>The subterranean storage facility includes a subterranean cavern (10) forming an underground cavity in which is disposed an immiscible displacing liquid (40). A plurality of concentric pipes extend from the surface into the cavity. As a cold fluid (50) at a sub-zero temperature is passed down a first flow bore (70) formed by the concentric pipes, the immiscible displacing fluid is passed in heat exchange relationship up a second flow bore (74) formed by the concentric pipes. The cold fluids are then stored within the cavity at a temperature and pressure consistent for safe storage.</p> |
