[History of Haichuan Pipeline] The longest hydrogen transmission pipeline "Baling-Changling" hydrogen pipeline

Thread Content

The "China Hydrogen Energy and Fuel Cell Industry White Paper" released by the China Hydrogen Energy Alliance in 2019 pointed out that the United States has 2,500 kilometers of hydrogen pipelines, Europe has 1,569 kilometers of hydrogen pipelines, and my country only has 100 kilometers of hydrogen pipelines. The total number of hydrogen pipelines worldwide is less than 4,500 kilometers, which is several orders of magnitude different from oil and gas pipelines. At present, low-pressure hydrogen pipeline transportation at home and abroad is still in the preliminary development stage. Cost is a factor restricting the development of hydrogen pipelines. Since hydrogen itself has a low volumetric energy density and is prone to "hydrogen embrittlement" on pipes, its pipeline transportation costs are often greater than the cost of natural gas pipeline transportation at the same energy flow rate. Data shows that in the United States, the cost of natural gas pipelines is only US$125,000-500,000/km, but the cost of hydrogen pipelines is approximately US$300,000-1 million/km, which is twice the cost of natural gas pipelines. my country's current hydrogen pipeline network is only 300-400km, and the longest hydrogen pipeline is the "Baling-Changling" hydrogen pipeline, with a total length of about 42km and a pressure of 4MPa. The construction scale of hydrogen refueling stations in China in 2019. From the first hydrogen refueling station put into operation in 2006 to the end of 2019, a total of 61 hydrogen refueling stations have been built in my country, of which 3 have been dismantled, 52 have been put into operation, and the number of hydrogen refueling stations under construction/planned is 72. Most of the hydrogenation stations built in my country from 2006 to 2015 are * * “The 863" project or the United Nations Development Program (UNDP) project to promote the commercial development of fuel cell vehicles in China mainly provides refueling services for fuel cell experimental vehicles and urban fuel cell public demonstration vehicles, but has not yet achieved commercial operation. The construction of hydrogen refueling stations began to accelerate after 2016, doubling from 2016 to 2018. The number of hydrogen refueling stations built in 2019 was twice that of 2018. The rapid growth trend is expected to continue. China's Hydrogen Energy Industry Production Capacity Forecast Analysis "China's Hydrogen Energy Industry Infrastructure Development Blue Book" predicts that by 2020, my country's hydrogen production capacity in the form of energy will reach 72 billion cubic meters, with 100 hydrogenation stations; 10,000 fuel cell vehicles; 50 hydrogen energy rail transit vehicles; and the total industry output value will reach 300 billion yuan. By 2030, the hydrogen energy industry will become my country's new economic growth point and an important part of the new energy strategy. The industrial output value will exceed 1 trillion yuan; the number of hydrogenation stations will reach 1,000, the number of fuel cell vehicles will reach 2 million, the construction mileage of high-pressure hydrogen long-distance pipelines will reach 3,000km, and the hydrogen energy industry infrastructure technology standard system will be nearly developed. * * At the same level, the development of hydrogen energy and fuel cell inspection and testing technology and the construction of service platforms form effective support for the development of the hydrogen energy industry.
