Today, as the wave of energy transition sweeps across the world, a "green artery" spanning three cities in Hebei Province has officially started construction. Recently, the Kangbao Caofeidian hydrogen long-distance pipeline has started construction in Zhangbei County, Zhangjiakou. This project, known as the "Green Hydrogen Great Wall", has broken industry records with five "world records", marking a new stage in the large-scale transportation of green hydrogen in China.

This world's largest green hydrogen transmission pipeline project is constructed by Zhangjiakou Haitai Hydrogen Energy Technology Co., Ltd. with a total investment of 13.5 billion yuan and a total length of approximately 1038 kilometers, running through 18 counties in Zhangjiakou, Chengde, and Tangshan. With a design pressure of 7.2 megapascals, a pipe diameter of 813 millimeters, an annual hydrogen transmission capacity of 1.5 million tons, and the highest steel grade material, the project has created five industry benchmarks, including the thickest pipe diameter, highest pressure, largest transmission capacity, longest distance, and best steel grade. The connection between the Kangbao hydrogen production base and the Caofeidian terminal market at both ends of the pipeline will effectively break the regional barrier between green hydrogen production and sales, and inject stable hydrogen sources into the Beijing Tianjin Hebei green chemical cluster.

The project construction party, Haitai Hydrogen Energy Technology, was established in 2023 and is a core platform under Haitai New Energy that focuses on the full chain development of hydrogen energy. As a green energy giant cultivated locally in Tangshan, its parent company started manufacturing photovoltaic modules in 2006 and has now formed four pillars: photovoltaic manufacturing, power station development, energy storage systems, and hydrogen energy industry. The company not only ranks among the top ten in the world with a 10GW module production capacity and has been rated as a BNEF Tier1 first tier manufacturer, but also has deep cooperation with companies such as Sharp and State Power Investment Corporation, with business radiating to many countries in Asia and the United States.

In the field of hydrogen energy, Haitai Group has invested over 15 billion yuan, and this pipeline project has become a key milestone in its strategic layout. In the next five years, the group plans to invest an additional 20 billion yuan to focus on the construction of liquefaction plants, hydrogen refueling station networks, and application scenarios, striving to become a leading hydrogen energy supplier in the Beijing Tianjin Hebei region.

However, the path of transformation is accompanied by pain. According to the third quarter financial report of 2025, Haitai New Energy's revenue was 1.432 billion yuan, a year-on-year decrease of 42.26%, and its net profit turned from profit to loss of 248 million yuan. Affected by a 30% drop in photovoltaic module prices, the gross profit margin plummeted to -3.35%. Faced with the cold winter of the industry, the company has decisively reduced its TOPCon battery investment by 5 billion yuan and instead increased its capital by 146 million yuan to promote the 2GW battery module project in Indonesia, accelerating its efforts to seek new growth opportunities overseas.

This winding "Green Hydrogen Great Wall" is not only an energy corridor composed of steel pipelines, but also carries the ambition of traditional energy enterprises to break through the situation and seek change. At a time when the red ocean of the photovoltaic industry is surging, Haitai New Energy is using hydrogen energy as a boat to navigate through cyclical waves. The success or failure of its strategic transformation may provide an important model for the entire new energy industry - as the old track becomes increasingly crowded, only enterprises that dare to sail towards the new blue ocean can win the future in this energy revolution.
