A large storage device filled with solid-state hydrogen was shipped from Shanghai's Waigaoqiao Port to Malaysia on March 11. This marks the first time China has achieved the maritime export of a large solid-state hydrogen storage device in a charged state, signifying a breakthrough in the country's hydrogen storage and transportation technology.

The storage unit uses China's self-developed magnesium-based solid-state hydrogen storage material and hydrogen absorption/release control technology, which allows hydrogen to be stored and transported at normal temperature and pressure conditions.

Hydrogen energy is regarded as a crucial part of the future energy system. However, traditional hydrogen storage and transportation technologies such as cryogenic liquefaction or high-pressure compression entail high operational costs and stringent safety requirements. In contrast, the new technology offers a safer and more economical solution.

The exported unit can hold up to one metric ton of hydrogen and has a lifespan exceeding 3,000 operational cycles, ensuring improved safety and more efficient storage and transport.

Industry insiders believe that the successful shipment of this large-scale solid-state hydrogen storage device in a charged state has expanded the application scenarios for hydrogen storage and transportation, opening new ground for fostering international cooperation on green and low-carbon technologies.
