ABSTRACT:
When a product such as ammonia, which is liquefiable under pressure and which is miscible with water is stored underground the storage takes place at the liquefaction pressure of the product and inside a double skin which defines an intermediate space (10), with both skins being inserted in a cavity (1) formed in a water-impregnated formation. The depth of the storage is so chosen that the hydrostatic pressure of the water in the formation is greater than the greatest expected pressure of the stored product, with the intermediate space being filled with water and being maintained at a pressure which is lower than the lowest expected pressure of the stored product. If the inner skin is punctured, NH.sub.3 is recovered in the water in the shaft (2) and does not escape to contaminate the water in the surrounding formation.
