BMW iX5 Hydrogen SUV introduces flat storage tank for extended range in 2028

Evolving advancements in hydrogen mobility are shaping the future of zero-emission driving, and BMW is taking a significant step forward with its upcoming BMW iX5 Hydrogen SUV. The next-generation model introduces a redesigned hydrogen storage concept aimed at improving both efficiency and practicality. By integrating a new flat tank system, BMW is addressing key limitations that have previously restricted the adoption of hydrogen fuel-cell electric vehicles (FCEVs). This innovation aligns with the company’s broader strategy of diversifying powertrain technologies while maintaining performance and usability across vehicle segments.

Flat Hydrogen Storage Redefines Space and Capacity

The core innovation lies in BMW’s newly developed Hydrogen Flat Storage system, which replaces conventional bulky cylindrical tanks. Unlike earlier designs, this new configuration fits seamlessly within the vehicle architecture, ensuring no intrusion into passenger or cargo space. This advancement allows the SUV to retain interior comfort while increasing hydrogen storage capacity. The system consists of seven interconnected carbon-fiber reinforced chambers forming a unified structure, enabling improved packaging efficiency and structural integrity.

Higher Capacity and Extended Driving Range

With the new storage design, the BMW iX5 Hydrogen SUV can store at least 7 kilograms of hydrogen, compared to approximately 6 kilograms in the current version. This increase directly translates into a longer driving range, estimated at around 750 kilometers. The improvement highlights BMW’s focus on making hydrogen vehicles more competitive with battery-electric alternatives. Additionally, refueling remains one of hydrogen’s strongest advantages, taking under five minutes to complete, offering convenience similar to conventional fuel vehicles.

Engineering Integration and Platform Flexibility

The hydrogen storage system operates at pressures up to 700 bar and is housed within a compact metal enclosure comparable in size to BMW’s next-generation 800-volt battery packs. This standardization enables flexible manufacturing, allowing multiple powertrain variants to be assembled on the same production line. Such an approach reduces complexity and cost, supporting BMW’s multi-energy platform strategy. Explore more innovations in hydrogen technology and vehicle platforms shaping modern mobility.

Multiple Powertrain Options for the Next X5

The upcoming X5 lineup, internally known as G65, will be offered with a wide range of propulsion systems. Alongside the hydrogen variant, customers will have access to gasoline, diesel, plug-in hybrid, and fully electric versions. This flexibility is made possible by the CLAR architecture, which is being enhanced with elements from BMW’s Neue Klasse platform.
