Recently, the world's largest green hydrogen transmission pipeline project, the Kangbao Caofeidian hydrogen long-distance pipeline, officially started construction in Zhangbei County, Zhangjiakou.

This giant project, known as the "Green Hydrogen Great Wall," was 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. With five "world's most" indicators including maximum pipe diameter, maximum pressure, maximum transmission capacity, longest distance, and highest steel grade, this project has become a benchmark project in the global hydrogen energy transportation field.  

The pipeline starts from Zhangjiakou Kangbao Hydrogen Production Plant and ends at Caofeidian Terminal Station in Tangshan City. The project passes through 18 counties in Zhangjiakou, Chengde, and Tangshan, with 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, and build a stable and reliable clean energy guarantee system for the green hydrogen, green ammonia, and green methanol industry clusters in the Beijing Tianjin Hebei region.  

It is reported that the construction and operation entity of this project is Zhangjiakou Haitai Hydrogen Energy Technology Co., Ltd., which was established in 2023 and is the core platform responsible for the development of hydrogen energy business within the Haitai new energy system. It is committed to building a hydrogen energy full industry chain covering hydrogen production, storage and transportation, refueling, and application.

Its parent company, Haitai New Energy, is a well-known enterprise in the field of green energy in China, founded in 2006 and headquartered in Tangshan City, Hebei Province.  

Haitai New Energy started with the manufacturing of photovoltaic modules and gradually developed into a comprehensive energy service provider covering four major sectors: photovoltaic manufacturing, power station development, energy storage systems, and hydrogen energy industry. The company has strong capabilities in the field of photovoltaics, with a global module production capacity of 10GW, ranking among the top ten Chinese photovoltaic enterprises in terms of production capacity, and has been rated as a Tier 1 module manufacturer by Bloomberg New Energy Finance.  

Haitai New Energy maintains long-term strategic cooperation with well-known domestic and foreign enterprises such as Sharp from Japan, State Power Investment Corporation, China Huadian, BYD, etc. Its business network covers multiple countries and regions in Asia, North America, etc.  

In terms of hydrogen energy layout, Haitai based enterprises have invested over 15 billion yuan in the hydrogen energy field, and the Kangbao Caofeidian hydrogen long-distance pipeline project is one of the most strategically significant layouts. Haitai New Energy is using the professional platform of Zhangjiakou Haitai Hydrogen Energy Technology to systematically layout the entire industry chain of hydrogen energy production, storage, transportation, and utilization.

In the next five years, Haitai New Energy plans to invest about 20 billion yuan in the hydrogen energy field, focusing on the construction of hydrogen liquefaction plants, hydrogen refueling station networks, and hydrogen energy application demonstration projects, to create the most influential hydrogen energy supply and service provider in the Beijing Tianjin Hebei region. In terms of performance, in the third quarter of 2025, Haitai New Energy's revenue was 1.432 billion yuan, a year-on-year decrease of 42.26%; The net profit changed from profit to loss, from a profit of 163 million yuan in the same period last year to a loss of 248 million yuan, a sharp decrease of 251.97% year-on-year.  

What is particularly severe is that the company's gross profit margin in the third quarter has dropped to -3.35%, falling into a vicious cycle of "the more sales, the greater the losses". This situation is mainly attributed to the severe overcapacity of global photovoltaic production capacity, with module prices falling by about 30% year-on-year and industry competition being exceptionally fierce.

Faced with the cold winter of the industry, Haitai New Energy quickly adjusted its strategic layout and decisively terminated the originally planned investment of 5 billion yuan in the "10GW TOPCon high-efficiency photovoltaic cell project". Instead, it increased its capital by 146 million yuan to its Indonesian subsidiary and promoted the construction of the "2GW solar cell+1GW module project" to accelerate the pace of overseas market expansion.Editor/Bian Wenjun
