BMW Hydrogen Technology Overview

With 45 years of experience in hydrogen and more than 20 in fuel-cell technology, the BMW Group is a pioneer in alternative drive technologies. As the energy transition continues, hydrogen has tremendous potential as a fuel of the future. Storable and transportable, it can be used in all kinds of ways. So, alongside electrical battery power, sustainably sourced hydrogen offers a further potential technology for sustainable individual mobility. That’s why the BMW Group is advocating not just for a better-developed charging grid but for an infrastructure of hydrogen fill- ing stations as well. BMW WILL LAUNCH THE FIRST HYDROGEN-POWERED PRODUCTIONMODEL IN 2028. After successfully testing the BMW iX5 Hydrogen pilot fleet worldwide, the BMW Group is now preparing for series production of vehicles with hydrogen drive systems in 2028 on the basis of the jointly developed next-generation powertrain technology. The series production models will be integrated into BMW’s existing portfolio, i.e. BMW will offer an existing model in an additional hydrogen fuel cell drive system variant. As FCEV technology is another elec- tric vehicle technology, the BMW Group explicitly views it as complementing the drive technology used by battery electric vehicles (BEV) and next to plug-in hybrid electric vehicles (PHEV) and internal combustion engines (ICE).

For the BMW iX5 Hydrogen, the BMW Group developed the world’s most powerful passenger-car fuel- cell system and a special, dedicated battery. Together, these two elements enable consistently high speeds and an electric output of 295 kW (401 hp) in total. Find out more about the development, pro- duction and workings of the BMW iX5 Hydrogen from our video. Since 2023 the BMW iX5 Hydrogen has been out on the road in various parts of the world to demonstrate the tech- nology and test it in different weathers and terrains. Hot-weather tests have exposed the vehicles to temperatures of up to 45°C as well as sand, dust, various inclines and fluctuating levels of humidity – and they performed impres- sively throughout. Hydrogen technology has also proven suitable for everyday use in extreme sub-zero temperatures, the fuel-cell drive performing just as well as a conventional combustion engine. Full system output is available within moments of the car starting, and not even the coldest conditions are enough to compromise range. The pilot fleet is still on the road in Europe, Japan, Korea, China, the US, and the Middle East. Through the pilot fleet, the BMW Group gained essential insights for further development of the fuel cell technology, but already demonstrated the everyday usability of hydrogen-powered mobility. TESTING WORLDWIDE. THE HISTORY OF HYDROGEN: THE KEY MILESTONES. In 1979, BMW developed the first experimental vehicle powered by liquid hydrogen, based on the BMW 5 Series 520 (E12). In the following years, ad- ditional hydrogen prototypes were built based on the BMW 7 Series (E23 and E32). In 2000, the first ever small series production of the BMW 750hL hydrogen model embarked on a World Tour. After successfully testing the

BMW iX5 Hydrogen pilot fleet worldwide, the BMW Group is now preparing for series production of vehicles with hydrogen drive systems in 2028. Hydrogen technology is a new and fascinating area within the field of drive technology and combines the best of both worlds: the advantages of electric driving and zero emissions, with the added benefit of fast refuelling like con- ventional vehicles. This section tells you more about key details and the components that will drive future mobility – from the fundamentals through to the refuelling infrastructure. WORK FOR PROGRESS: TRANSFORMATION OF THE MOBILITY SECTOR.

A NEW LEVEL OF PARTNERSHIP. A core component of the BMW iX5 Hydrogen is the fuel-cell system, which offers consistently high output of 125 kW/170 hp. The individual cells are manufactured for the BMW Group by the Toyota Motor Corporation. In September 2024 the BMW Group and Toyota Motor Corporation take col- laboration to the next level. Both companies are pooling their innovative strength and their technological capabilities to bring a new generation of fuel cell powertrain technology to the roads. TECHNOLOGY DRIVES INNOVATION. The drive of the BMW iX5 Hydrogen consists of an innovative combination of fuel cells delivering 125 kW/170 hp, an electric motor from the BMW Group’s Gen-5 range of BMW eDrive technologies, and a specially devel- oped battery. Together, these offer a combined output of up to 285 kW/401 hp . Underpinning the BMW X5-based hydrogen car is a framework of two hydrogen tanks, the fuel cells and the electric motor. Inside the fuel cell, hydrogen from the tanks reacts with oxygen from the at- mosphere to produce electricity to power the motor. The dedicated hydro- gen components – including the high-revolution compressor with turbine and the high-voltage coolant pump – were also developed by the BMW Group. THE FUTURE OF REFUELLING. Refuelling a hydrogen car is a lot like refuelling a car with a combustion en- gine: filling the tank takes just three to four minutes. The two tanks in the BMW iX5 Hydrogen can hold a total of 6 kg of the gas , giving the vehicle a range of 504 km in the WLTP cycle. Compared with recharging a battery- electric car, hydrogen refuelling is faster and therefore especially useful for long-distance travellers. By trialling its pilot fleet worldwide, the BMW Group is doing much to support the development of a hydrogen fuel in- frastructure to serve passenger cars as well as commercial vehicles. An in- ternational hydrogen network is a prerequisite for us to launch our offer to customers. HYDROGEN IN PLANT.

In 2013 we erected Germany’s first indoor hydrogen station – at Plant Leipzig. But we are also trialling hydrogen technology to decarbonise transport lo- gistics beyond the factory gates, as a partner in research projects such as H2HAUL and HyCET. Within the company, the paintshop at Plant Leipzig is currently piloting the use of hydrogen in vehicle production. DIE NEUESTEN INSIGHTS RUND UM BMW GROUP WASSERSTOFF-TECHNOLOGIE.
