  • Patent number: 11180318
    Abstract: The invention generally relates to a method and system for storing hydrogen product in a salt cavern. The method is directed to substantially confining a high purity hydrogen stored within the salt cavern by maintaining the stored hydrogen at a pressure between a lower limit and an upper limit within the cavern, whereby the salt cavern forms a substantially impermeable barrier to the stored hydrogen therein between the lower limit and the upper limit and wherein the improvement over the predicate art enables the upper limit to exceed about 1 psi per liner foot of cavern depth.

  • Patent number: 9656807
    Abstract: A method of pad gas management in an underground storage volume including storing a first compressible fluid, determining a transient minimum operating pressure (Ptrans), measuring the pressure (Pact), removing at least a portion of the first compressible fluid, concurrently, introducing an incompressible fluid, thereby producing a transient pressure condition controlled by the flow rate of the incompressible fluid, such that Ptrans<Pact. The method may also include a length of casing, permanently cemented into the surrounding rock formations, with a final cemented casing shoe defining the practical endpoint at an approximate depth (Dcasing), determining a transient pressure gradient (Gtrans) for the underground storage volume, wherein Ptrans<Dcasing√óGtrans. The maximum removal of the first compressible fluid is controlled such that Pmin<Pact, and wherein the transient pressure condition has a duration (D) of less than 7 days, more preferably less than 5 days.

  • Patent number: 9372603
    Abstract: Techniques are disclosed for presenting users with relevant data and statistics related to the operations of an industrial system. Data obtained by a SCADA system may be stored in a real-time status database (which reflects the current process data of the industrial system) and a historian database (which archives the process data from the industrial system as it changes over time). A user may request from the SCADA system process data obtained during a specified period of time. The request may be subdivided into a plurality of time intervals, and process data associated with each time interval may be analyzed to determine one or more salient values that are representative of the interval. The salient values associated with each time interval then may be transmitted to the user in response to the process data request.

  • Patent number: 9202198
    Abstract: Techniques are disclosed for managing certain aspects of a large industrial operation (such as a pipeline). A commodity materials invoice system may allow a user to model a commodity invoice as a template and subsequently use that template to model commodity usage for different periods of time. Costs for a given billing period may be estimated based on actual commodity consumption. For example, data from a SCADA system monitoring different aspects of a pipeline may be used to estimate invoice costs for retail commodity consumption. The commodity materials invoice system may be configured to present both estimated and actualized invoice data side-by-side, allowing users to make a direct comparison of the estimated and actualized invoice data.
