On April 27, 2022, China’s leading stainless steel manufacturer: SXTG Stainless Steel Technology Corporation’s newly developed stainless steel products for liquid hydrogen storage containers and passed relevant certifications, becoming the only supplier of such products in China, and the world’s largest hydrogen energy infrastructure Leading companies have signed bulk orders, and their products are used in Asia’s largest hydrogen energy project.
The successful development of special stainless steel for liquid hydrogen storage containers has successfully filled the gap of stainless steel used for civil liquid hydrogen pressure vessels in China, and promoted the construction and improvement of relevant material standards 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. Liquid hydrogen has a high hydrogen storage density, and 1m3 of liquid hydrogen is equivalent to 800m3 of gaseous hydrogen. Under 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, convenient measurement, etc. It is more suitable for large-scale storage and transportation, and has better future prospects. for good.
At present, developed countries mainly focus on liquid hydrogen storage and transportation (more than 70%). However, due to the insufficient research on the low-temperature structure and properties of materials in liquid hydrogen environment in China, and the lack of theoretical support and unified standards for material selection, China’s liquid hydrogen is mainly used. It is used in aerospace and other fields, and it is almost blank in civilian use.
SXTG predicts the potential of the booming development of the hydrogen energy industry, actively participates in the cooperation with China’s national energy management department and with enterprises in the hydrogen energy manufacturing industry chain, actively participates in the design and development of materials, and promotes the formulation of relevant material standards.
Successfully developed special stainless steel series (plates, tubes, shapes) materials for liquid hydrogen containers. The product chemical composition, ultra-low temperature performance (-269°C) and other indicators fully meet the harsh requirements of the liquid hydrogen environment, contributing to the green transformation and upgrading of China’s energy.
