100-kilogram class vehicle-mounted liquid hydrogen system made by China Aerospace Science and Technology Corporation (CASC)

In Beijing, the unveiling of "Track 1000," a 100-kilogram vehicle-mounted liquid hydrogen system, marks a significant milestone achieved by China Aerospace Science and Technology Corporation (CASC). This groundbreaking product stands as a cornerstone in the advancement of liquid hydrogen technology within China's transportation sector, particularly in extending the driving range of hydrogen-heavy trucks to surpass 1,000 kilometers. Such innovation represents a pivotal leap forward in the integration of liquid hydrogen within the nation's transportation infrastructure.

The development of liquid hydrogen heavy trucks heralds a new era of "zero emissions" for heavy-duty vehicles. This journey began in 2020 with the introduction of the world's first liquid hydrogen heavy truck featuring the 80-kilogram system pioneered by the 101 Institute. By 2023, the successful domestic implementation of the "Research on Key Technologies for Heavy-Duty Vehicle Liquid Hydrogen Storage and Supply" project further solidified China's leadership in the field, seamlessly integrating liquid hydrogen systems into heavy-duty vehicles.

As the inaugural 100-kilogram vehicle-mounted liquid hydrogen system in the country, this new generation system embodies forward-thinking design principles and modular concepts. Meticulous optimization and integration across storage, supply, and refueling processes have resulted in the construction of five major modules: liquid hydrogen cylinder, valve box, vaporization buffer, control, and load-bearing structure. All components are domestically produced, with independently controllable core technology. Moreover, the establishment of China's sole key component and system-level testing facility for vehicle-mounted liquid hydrogen systems underscores a commitment to quality and innovation.

This latest iteration boasts notable enhancements, including a 20% increase in effective volume within the same outer dimensions, elevated hydrogen carrying capacity of 100 kilograms, and a liquid hydrogen cylinder mass hydrogen storage density reaching 12%. With an overall system hydrogen storage density surpassing 10%, coupled with the successful development of China's first dedicated hydrogenation and gas return interfaces, the performance benchmarks achieved are truly remarkable.

The China Aerospace Science and Technology Corporation (CASC) asserts that the successful development of the 100-kilogram vehicle-mounted liquid hydrogen system represents a significant stride in advancing new energy technologies and enhancing national productivity. Notably, substantial cost reductions have been realized with this new generation of products, with further decreases anticipated through mass production and demonstration applications. This trajectory promises to elevate China's liquid hydrogen heavy truck development to unprecedented heights.

Looking ahead, the China Aerospace Science and Technology Corporation (CASC) remains committed to driving key technological research and fostering the transformation of scientific achievements in the liquid hydrogen domain. By cultivating an open innovation ecosystem, catalyzing breakthroughs, and facilitating iterative product upgrades, the academy aims to expedite the launch of cutting-edge products, including vehicle-mounted liquid hydrogen systems, liquid hydrogen refueling stations, and high-efficiency filling and transfer equipment. In doing so, they aim to fortify China's aerospace prowess and accelerate the development of new productivity within the liquid hydrogen heavy truck sector.
