[The world's largest green hydrogen pipeline project starts construction] Recently, the world's largest green hydrogen transmission pipeline project, the Kangbao Caofeidian hydrogen long-distance pipeline, officially started construction in Zhangjiakou, Hebei. The project is constructed by Zhangjiakou Haitai Hydrogen Energy Technology Co., Ltd. with a total investment of 13.45 billion yuan and a total pipeline length of approximately 1038 kilometers. With its five "world records" in diameter, pressure, transmission capacity, distance, and steel grade, it has become a benchmark project in the global hydrogen energy transportation field. The pipeline starts from Zhangjiakou Kangbao Hydrogen Production Plant and ends at Tangshan Caofeidian Terminal Station, passing through 3 cities and 18 counties. It has a design pressure of 7.2 megapascals, a pipe diameter of 813 millimeters, and an annual hydrogen transmission capacity of over 1.5 million tons. This new energy artery will effectively solve the geographical separation problem between green hydrogen production and consumption markets, providing stable and reliable clean energy guarantees for the green hydrogen based energy industry cluster in the Beijing Tianjin Hebei region. It is reported that the project construction and operation party, Haitai Hydrogen Energy Technology, was established in 2023 and is the core platform under Haitai New Energy that focuses on hydrogen energy business. Faced with pressure on performance in the third quarter of 2025, Haitai New Energy is accelerating its strategic adjustment. While terminating its domestic 5 billion yuan photovoltaic cell project, it is actively expanding into the entire hydrogen energy industry chain and overseas markets, committed to building the most influential hydrogen energy supply and service provider in the Beijing Tianjin Hebei region.
