In the era of new energy vehicles, hydrogen energy vehicles have attracted much attention. It is not only zero-emission and environmentally friendly, but also has a long range and fast refueling, which is known as the "ultimate green travel" solution. However, there is a big bottleneck in the development of hydrogen energy vehicles, that is, the cruising range is insufficient.
The good news is that China Aerospace Science and Technology Corporation has actively deployed in the field of new energy and made a major breakthrough - independently developed the first 100-kilogram vehicle-mounted liquid hydrogen system "Track 1000" in China. This innovative product will bring a range of more than 1,000 kilometers to the hydrogen fuel cell heavy-duty truck.
Traditionally, hydrogen has been stored using compressed hydrogen, but this method is low in density and large in volume. The storage density of liquid hydrogen is dozens of times higher, making it an ideal choice for automotive hydrogen storage. However, in order to safely and efficiently store ultra-low temperature liquid hydrogen and gasify it for the fuel cell system in a timely manner, the design requirements for the storage and transportation system are extremely strict and precise.
"Track1000" adopts a forward design and modular concept, and modularizes and integrates functions such as liquid hydrogen storage, transportation, and gasification through deep integration and optimization. Just like the aerospace liquid rocket engine, each module has a reasonable division of labor and close coordination to ensure the efficient use of liquid hydrogen, safe and controllable.
The core technology of the product is completely independent and controllable, and all parts and components are localized, breaking the monopoly of foreign technology. Under the same dimensions, the effective volume is increased by 20%, and it can store up to 100 kilograms of liquid hydrogen, the mass hydrogen storage density of liquid hydrogen cylinders reaches 12%, and the hydrogen storage density of the overall system exceeds 10%, which refreshes the record of similar products at home and abroad.
What's more gratifying is that through a series of innovative design and supply chain management, the development cost of the product has been greatly reduced, and it is expected to further reduce the price after mass production in the future. This will strongly promote the large-scale commercial application of liquid hydrogen heavy trucks in transportation, logistics and other fields, and help achieve the "double carbon" goal.
This independent and controllable domestic liquid hydrogen storage and transportation system marks a major breakthrough in the core system of new energy vehicles in the mainland, demonstrates China's innovation strength to the world, and will greatly accelerate the industrialization process of hydrogen energy vehicles in the mainland.
