HYDROGEN LEAK DETECTION SYSTEM, HYDROGEN LEAK DETECTION METHOD, AND HYDROGEN TRANSPORT PIPELINE CAPABLE OF HYDROGEN LEAK DETECTION

WIPO Patent Application WO/2023/027526

A1

A hydrogen leak detection system of a hydrogen transport pipeline, which comprises a pipe-shaped transport inner pipe for transporting a hydrogen fluid, and an outer protection layer surrounding the outer circumference of the transport inner pipe, comprises: one or more optical fiber unit which is disposed along the length direction of the hydrogen transport pipeline and comprises one or more optical fiber for detecting hydrogen leaking from the transport inner pipe, and an optical fiber protection layer surrounding the one or more optical fiber; a hydrogen detection unit which comprises an optical signal generator for providing an optical signal to the one or more optical fiber, and an optical characteristics detection unit capable of detecting the optical characteristics of the one or more optical fiber; and a control unit which stores a normal optical characteristics range of the one or more optical fiber, for a normal state where hydrogen is not detected from the one or more optical fiber, and determines that hydrogen is leaking from the hydrogen transport pipeline if the optical characteristics value of the one or more optical fiber, detected by the optical characteristics detection unit, is determined to exceed the normal optical characteristics range.
