On the 13th, it was learned from the Sixth Academy of China Aerospace Science and Technology Group that the research on key technologies for liquid hydrogen storage and supply in heavy-duty vehicles, led by the 101 Institute of the Academy, has made significant breakthroughs. The project took three years to complete seven key technological breakthroughs in vehicle mounted liquid hydrogen storage and supply systems. It is reported that the project has optimized the configuration of the vehicle mounted liquid hydrogen storage and supply system, fuel cell power system, and heavy-duty vehicle chassis structure. It has taken the lead in developing an engineering prototype of an 80 kilogram vehicle mounted liquid hydrogen storage and supply system in China; We have completed compatibility testing between the liquid hydrogen storage and supply system, fuel cells, and the entire vehicle. We have passed the on-site assessment on the test track and are on par with international counterparts in terms of mass and volume hydrogen storage density, unit energy consumption, and hydrogen supply rate; A testing device for vehicle mounted liquid hydrogen storage and supply system has been developed, and a testing method for vehicle mounted liquid hydrogen storage and supply system has been established, providing necessary standard basis for technical research and product testing. The research team has achieved the integration and application of liquid hydrogen storage and supply system with heavy-duty vehicle fuel cell power system and whole vehicle through this project, solving the two major problems of heavy-duty truck electrification power performance and range. It is reported that a 49 ton diesel heavy-duty truck emits carbon dioxide equivalent to the emissions of 40 small cars. Compared with 49 ton diesel heavy-duty trucks, each liquid hydrogen heavy-duty truck can reduce carbon emissions by 140 tons per year, achieving zero emissions for long-distance heavy-duty vehicles. In the future, 101 Institute will continue to promote key technological breakthroughs and the transformation of scientific and technological achievements, accelerate the landing of demonstration projects for the entire liquid hydrogen industry chain, and actively build an ecological chain for the liquid hydrogen industry.
