Abstract:
A hydrogen pipeline detonation arrestor is provided. The detonation arrestor includes a pipeline spool, having a segment length, an inner volume, an outer surface. The detonation arrester also includes a detonation barrier having a plurality of axially aligned quench pipes located within the inner volume. The detonation arrester is located within a hydrogen pipeline upstream or downstream of a hydrogen salt cavern storage facility.
Abstract:
A cavern pressure control method includes storing compressible and possibly incompressible fluids in an underground storage volume, removing a portion or introducing additional incompressible fluid into the underground storage volume, possibly removing a portion or introducing additional compressible fluid into the underground storage volume, thereby producing a net pressure increase rate (Pinc) within the underground storage volume, wherein Pinc is maintained at less than a predetermined maximum increase value (PImax).
Abstract:
This method includes providing an cased borehole located within a salt bed, injecting an aqueous liquid into the cased borehole at a first pressure, in order to expose the salt bed to the aqueous liquid, thereby dissolving at least a portion of the salt bed and forming a brine solution within an underground storage volume, withdrawing at least a portion of the brine solution from the underground storage volume, and injecting an inert gas into the cased borehole at a second pressure, in order to provide an inert blanket within the underground storage volume, wherein the second pressure is greater than the first pressure but less than the maximum allowable pressure of the cavern.

Abstract:
A storage wellhead allowing on-line system maintenance and testing is provided. Including at least two fluidically parallel gas passages adapted to allow testing or maintenance of one gas passage, while the other gas passage remains in service. The gas may be hydrogen. Also including at least two fluidically parallel liquid passages adapted to allow testing or maintenance of one liquid passage, while the other liquid passage remains in service. The liquid may be brine.
