recently, the 500kg magnesium-based solid-state hydrogen storage cycle equipment developed by Hami hydrogen energy equipment in cooperation with academician ding wenjiang team of Shanghai jiaotong university has arrived in Hami, Xinjiang, and will soon be put into local demonstration application. This landing marks a breakthrough practice of magnesium-based solid-state hydrogen storage technology in the field of wind and electricity consumption and green hydrogen storage and transportation in Xinjiang, laying a solid foundation for the declaration of the first set of the autonomous region.
As a new generation of solid-state hydrogen storage technology, the equipment uses magnesium-based alloy hydrogen storage materials with high hydrogen storage density and strong safety. It can directly replace the traditional 20MPa high-pressure long-tube trailer and realize large-scale, long-distance, safe and efficient hydrogen storage and transportation at normal temperature and pressure.
Magnesium-based solid-state hydrogen storage technology is to store hydrogen in the material in solid form through the chemical reaction of hydrogen and magnesium alloy. The significant advantage of this technology is the high hydrogen storage mass density and high safety performance. The mass density of magnesium-based solid-state hydrogen storage can reach 6.4wt%, I .e. 15.6 tons of material can store 1 ton of hydrogen, and the hydrogen storage process is carried out under normal temperature and pressure, with stable performance and no leakage under high pressure. The technology is suitable for truck, railway or water transportation, making hydrogen storage and transportation more convenient and flexible.
From the perspective of policy orientation, the hydrogen energy pilot of the three ministries and commissions clearly listed “demonstration and application of hydrogen storage and transportation technology” as a key task, and encouraged the development of multi-technical routes such as high-pressure gaseous, liquid hydrogen and solid hydrogen storage. Magnesium-based solid-state hydrogen storage has been included in the pilot program of Beijing-Tianjin-Hebei, Yangtze River Delta and other urban agglomerations by virtue of its comparative advantages in safety and cost, and will carry out large-scale demonstrations in scenarios such as hydrogen energy heavy trucks, distributed energy storage and ship power.
In recent years, magnesium-based hydrogen storage technology has ushered in a breakthrough. In terms of material modification, through nanocrystallization, alloying and catalyst doping technologies, the hydrogen absorption and desorption temperature of magnesium-based hydrogen storage materials has been reduced from above 300 ℃ to 150-200 ℃, the hydrogen absorption and desorption rate has been increased by 3-5 times, and the cycle stability has exceeded 1000 times, which has met the practical application requirements of on-board hydrogen storage, distributed energy storage and other scenarios.
in terms of industrialization, domestic enterprises have achieved mass production of tons of magnesium-based hydrogen storage equipment. what is more noteworthy is that China’s magnesium-based hydrogen storage materials have been exported by commercial sea. on March 12, 2026, the first batch of magnesium-based solid hydrogen storage products of meilong enterprise Shanghai hydrogen maple energy technology co., ltd. were shipped from the fourth phase terminal of Shanghai Waigaoqiao port area for export and officially shipped to Malaysian customers, it marks a new path for China’s hydrogen energy storage and transportation to sea.
