BMW unveils Hydrogen Flat Storage for iX5 at Beijing auto show, offering 750 km range and 5-min refueling. Mass production planned for 2028.
BMW took the wraps off a key innovation for its iX5 Hydrogen fuel-cell crossover at the Beijing auto show: a new hydrogen storage system called Hydrogen Flat Storage. The technology is designed to boost range and make it easier to integrate hydrogen powertrains into mass-produced vehicles.© B. Naumkin for .NewsAt the heart of the system is a single module composed of seven lightweight composite tanks rated for 700 bar of pressure. Unlike conventional setups that use separate reservoirs, this design features a linked structure with a central valve. That approach allows for a more efficient layout within the body, improves overall system efficiency, and opens up new possibilities for future hydrogen-vehicle design.The total hydrogen capacity is around 7 kg, giving the iX5 Hydrogen a range of up to 750 km. Refueling takes less than five minutes—a key advantage over battery-electric vehicles, which require significantly longer charging times.© B. Naumkin for .NewsThe new storage system was designed from the start for the X5 architecture and is fully compatible with sixth-generation battery packs. This means BMW can build hydrogen versions on the same production line as gasoline, hybrid, and electric models, which simplifies and lowers the cost of mass production.The iX5 Hydrogen also comes with third-generation fuel cells and a new intelligent control system called Heart of Joy, which coordinates the powertrain and chassis.© B. Naumkin for .NewsBMW is sticking with its “technology-neutral” strategy, pursuing several paths at once. Hydrogen is seen as an effective complement to EVs, especially for long trips and quick energy replenishment. Mass production of the hydrogen iX5 is slated for 2028.
