Article Abstract
- The brand new Hydrogen Flat Storage system consists of seven carbon-fibre bolstered chambers linked as a single unit, storing at the very least 7 kg of hydrogen and filling in beneath 5 minutes.
- The flat design is suitable with the Gen6 battery flooring bundle, permitting the iX5 Hydrogen to share a manufacturing line with all 5 X5 drivetrain variants.
- BMW is focusing on 2028 to carry the iX5 Hydrogen into wider manufacturing, paired with the most recent Gen3 gasoline cell expertise.
BMW has developed a brand new hydrogen storage system for the iX5 Hydrogen that pushes vary as much as 750 kilometers (385 miles) and does it with out giving up any cabin house. The corporate calls it the Hydrogen Flat Storage system, and it replaces the earlier association of separate cylindrical strain vessels with one thing significantly extra compact.
As a substitute of separate cylindrical strain vessels — which is how most hydrogen vehicles have performed it — there at the moment are seven chambers constructed from carbon-fiber bolstered composite, all joined collectively in a single enclosed unit with one central valve. They sit in a metallic body and are rated to 700 bar. Whole capability is at the very least seven kilograms of hydrogen. Fill time from empty is beneath 5 minutes.
A New Tech Design
The flatter, extra built-in form is the entire level. It traces up with the identical flooring geometry BMW makes use of for the Gen6 high-voltage battery, which suggests the hydrogen drivetrain matches into the X5 platform with out consuming into the cabin or the boot. In response to BMW, the rear passengers don’t lose legroom and the cargo space shouldn’t endure from it.
Dr. Joachim Submit, the board member answerable for growth, described the packaging problem as “set up Tetris.” In case you recall, BMW is constructing the new X5 in 5 totally different powertrain configurations — full electrical, plug-in hybrid, standard combustion, delicate hybrid, and now hydrogen — all on the identical manufacturing line. For that to work, each variant has to suit throughout the similar dimensional envelope.
On the powertrain facet, the iX5 Hydrogen will get the most recent Gen3 gasoline cell, which is extra environment friendly and extra highly effective than the unit within the present mannequin. It’s paired with a high-voltage battery, and the entire system runs by way of BMW’s Coronary heart of Pleasure chassis software program and Dynamic Efficiency Management. BMW says the driving expertise is supposed to be indistinguishable from another X5 within the vary, which has all the time been the tougher a part of the hydrogen argument to make convincingly.
BMW is focusing on 2028 to carry the iX5 Hydrogen into its broader manufacturing community. The present era has been operating in a restricted pilot fleet — largely in Europe and California — so 2028 represents the primary actual transfer towards one thing individuals can really purchase. Whether or not the hydrogen refueling infrastructure retains tempo with that timeline is a separate query, and a tougher one to reply.
