How can hydrogen technology be integrated into a car in a way that combines greater range, faster refuelling and BMW’s trademark sheer driving pleasure? The answer lies in the BMW iX5 Hydrogen – and it’s as clever as it is elegant: the new BMW Hydrogen Flat Storage system. With its innovative geometry, the new system stores around seven kilograms of hydrogen and takes less than five minutes to refuel. Technology-open approach meets the art of engineering: New hydrogen tank system in the BMW iX5 Hydrogen. Clever storage, more range. When it comes to hydrogen in the BMW X5, the powertrain is only part of the equation. Equally important is how the fuel storage system is integrated – and that’s where BMW’s latest tank technology comes into play. The BMW Hydrogen Flat Storage system in the BMW iX5 Hydrogen is a case in point. Its new arrangement and tank size not only offer a higher range of up to 750 kilometres1 but also have the added advantage of making exceptionally efficient use of the available installation space. That means the new system is fully compatible with the Gen6 high-voltage battery – without compromising on space inside the cabin. It also means models with fuel cell technology can be built on the same production line as other models. The 700-bar high-pressure hydrogen tanks additionally benefit from the mechanical protection provided by the vehicle structure, increasing safety even further. All-new storage system increases range. The new flat tank system consists of seven high-pressure tanks made of carbon fibre-reinforced composite, which are connected in parallel and integrated into a robust metal frame. What sets this design apart is that, instead of individual pressure vessels, multiple chambers are connected to form an enclosed unit controlled by a central main valve. This optimised storage concept increases
