Document Type and Number:
WIPO Patent Application WO/2024/032286
Kind Code:
A1
Abstract:
Disclosed is a direct-current superconducting liquid hydrogen energy pipeline system with liquid nitrogen cold shields. The system comprises a superconducting energy pipeline system starting station A, a superconducting energy pipeline system intermediate station B and a superconducting energy pipeline system terminal station C, which are sequentially connected by means of a liquid hydrogen superconducting pipeline with a liquid nitrogen cold shield, wherein the liquid hydrogen superconducting pipeline with the liquid nitrogen cold shield comprises liquid hydrogen conveying pipelines (9, 30), liquid nitrogen cold shield layers (10, 16, 32, 35), external cold insulation layers (11, 33), and superconducting cable groups (8, 29), which are arranged inside the liquid hydrogen conveying pipeline; liquid nitrogen cold shields (10, 16, 32, 35) are arranged outside the liquid hydrogen conveying pipeline in a segmented manner, and the bottom and top of each segment of liquid nitrogen cold shield are respectively connected to a liquid nitrogen supply pipeline (12) and a nitrogen recovery pipeline (14) by means of pipelines. The pipeline system is applied to a large-scale new energy base for direct-current superconducting power transmission, rich power can be used for water electrolysis hydrogen production, and prepared hydrogen can be used for providing a low-temperature environment for realizing superconducting after being liquefied, such that the whole system can achieve the advantages of large-capacity, low-loss and high-efficiency transmission of energy, and cooperative hydrogen-power complementation.
