摘要

A method of maintaining pressure in an underground storage volume during transient operation is presented. Including storing a first compressible fluid, determining a safe minimum operating pressure (Pmin), and a safe maximum operating pressure (Pmax), measuring the pressure (Pact), removing or introducing the first compressible fluid, and concurrently, introducing or removing an incompressible wherein the flow rate of the incompressible fluid is controlled such that Pmin

1. A method of maintaining pressure in an underground salt cavern during transient operation, comprising:
storing a first compressible fluid hydrogen in an underground salt cavern, determining a safe minimum operating pressure (Pmin), and a safe maximum operating pressure (Pmax) for said underground salt cavern necessary to maintain salt cavern integrity, measuring the pressure (Pact), of said underground salt cavern, removing at least a portion of said first compressible fluid from said underground salt cavern, concurrently, introducing a flow of an incompressible fluid into said underground salt cavern,wherein the flow of said incompressible fluid is controlled such that Pmin
