【History of Haichuan Pipelines】Gansu Province’s first medium-to-long-distance hydrogen transport pipeline began construction at the Yumen Oilfield

Thread Content

Gansu Province’s first medium-to-long-distance hydrogen pipeline was recently put under construction at the Yumen Oilfield. This is also another major new energy project launched by the Yumen Oil Field following the successful operation of its 200-megawatt photovoltaic power generation demonstration project in 2021. This hydrogen pipeline project connects to the hydrogen refueling station at Yumen Refinery; it is the first medium-to-long-distance pure hydrogen pipeline in Gansu Province. The project plans to build a hydrogen pipeline with a diameter of 200 millimeters, a length of 5.77 kilometers, a hydrogen transport capacity of 10,000 standard cubic meters per hour, and a pressure of 2.5 megapascals. It is expected to be completed and put into operation by the end of June, thereby meeting the hydrogen needs of the Yumen Refinery and local enterprises more effectively. At present, the Yumen Oilfield makes full use of the abundant hydrogen resources available at the refining and chemical complex. A hydrogen refueling station has been built and put into operation; it covers an area of 9,000 square meters and incorporates hydrogen compression, loading systems, and storage facilities. The hydrogen filling pressure is 20 megapascals, with a filling capacity of 3,000 standard cubic meters per hour, and the purity of the hydrogen remains above 99.9%. This project has initially established a hydrogen supply chain in provinces and regions such as Gansu, Ningxia, and Xinjiang, with a total of 460,000 standard cubic meters of hydrogen sold to date. The Yumen Oilfield is known as the “cradle of China’s petroleum industry,” and it has been designated as the key enterprise in Gansu Province’s hydrogen energy industry chain. According to the Yumen Oilfield, the company is actively promoting the industrial application of green hydrogen in areas such as hydrogen-rich energy production, hydrogen metallurgy, public transportation, and logistics. It aims to establish a green hydrogen supply center with an annual production capacity of 50,000 tons by the end of the 14th Five-Year Plan period, thereby driving the transformation of the oilfield’s energy structure.
