Mass hydrogen storage density of IV hydrogen storage bottle for unpotential energy of Great Wall Group exceeds 6.1wt%.
CTOnews.com, February 9, the Great Wall Group announced that the second generation 70MPa-57L Ⅳ hydrogen storage bottle independently developed has made a breakthrough, with a mass hydrogen storage density of 6.1wt%, exceeding the US Department of Energy (DOE) target of 5.5wt% for 2025, and better than the current international market mainstream brands of similar products, reaching the world's leading level. It is mainly suitable for on-board hydrogen storage system of hydrogen fuel cell passenger vehicle.
IV hydrogen storage bottle product effect map at the same time, based on the application needs of different market scenarios and different customer types, the whole series product planning of unpotential energy IV hydrogen storage bottle has been promoted synchronously, and the working pressure covers 35MPa and 70MPa, including product sequences of different specifications and models, such as 70MPa-23L and 35MPa-210L. The mass hydrogen storage density index of some commercial vehicle IV hydrogen storage bottles can reach 6.8wt%. And all the products have achieved 100% self-control of key core technologies, 100% localization of key raw materials (such as carbon fiber) and core components (such as bottle mouth valves, inner tanks, etc.), and a 20% reduction in comprehensive cost. and has lightweight, long life, high safety and other comprehensive performance advantages, and will be released in the near future, can provide customized product development Widely used in fuel cell passenger vehicles, commercial vehicles (heavy trucks, buses, cold chain logistics vehicles), ships and other scenarios and fields.
CTOnews.com learned that the second-generation IV hydrogen storage bottle series independently developed by Unpotential Energy has successively completed fire test, durability test, use performance test, and other key test projects, the construction of the production line has entered the end, and the related work of the "three new" reviews is being promoted in an orderly manner.
