On June 15, 2022, China's most advanced stainless steel manufacturer: TGJT Stainless Steel Technology Corporation released stainless steel products for liquid hydrogen and passed the certification, becoming the only Chinese supplier of such products, and the world's largest hydrogen producer and hydrogen energy foundation Leading companies in the facility field have signed bulk orders, and the products will be used in Asia's largest hydrogen energy project.
The development of this special stainless steel for liquid hydrogen has successfully filled the blank of stainless steel used for civil liquid hydrogen pressure vessels in China.
Hydrogen energy has the advantages of high combustion calorific value, zero pollution, abundant reserves, and easy conversion with various energy sources, and can achieve truly green, efficient and sustainable development.
Globally, the storage and transportation of hydrogen energy is mainly in high-pressure gaseous state and low-temperature liquid state. In the absence of the technical background of large-scale pipeline hydrogen transportation, compared with high-pressure storage and transportation, liquid hydrogen storage and transportation has the advantages of low transportation cost, high hydrogen purity, and convenient measurement. It is more suitable for large-scale storage and transportation, and has better future prospects. for good. Since China's research on the low-temperature structure and properties of materials in the liquid hydrogen environment is not perfect, the material selection lacks theoretical support and unified standards, resulting in almost blank civil applications.
In response to this situation, TGJT cooperates with relevant national departments and manufacturing enterprises, actively participates in the design and development of materials, and promotes the formulation of relevant material standards. It took one year to successfully develop special stainless steel series (plates, tubes, shapes) materials for liquid hydrogen containers. The product chemical composition, ultra-low temperature performance (-269℃) and other indicators fully meet the harsh requirements of the liquid hydrogen environment, which is the green transformation and upgrading of China's energy. contributed strength.
