Last Tuesday, Oliver Zipse, Chairman of the Board of Management of BMW AG, officially opened the BMW Group plant in Debrecen. The BMW Group’s newest and most innovative production site marks the beginning of a new era for the company.
Meanwhile, BMW Group Plant Leipzig is planning a hydrogen pipeline link, paving the way for it to become the first car plant in the world to receive hydrogen via a pipeline.
iFactory Debrecen
In late October, the new BMW iX3 will enter series production in the Hungarian university town of Debrecen as the first vehicle of the Neue Klasse. Plant Debrecen was planned virtually and fully realised in practice, aligning with the principles of the BMW iFACTORY, making it the first BMW Group car plant to rely entirely on electricity from renewable energy during regular operation.
“In our global production network, our new plant in Debrecen is a pioneer: it is our first fully-electric plant, the first production site to operate entirely without fossil fuels, and the first to build vehicles for the Neue Klasse. This makes our plant in Debrecen a decisive factor in the BMW Group’s future success,” said Oliver Zipse. “
The opening also sends a strong signal: we are expanding our footprint on our home continent and reaffirming our commitment to Europe as a strong and competitive location for industry,” he added.
Network plant
Plant Debrecen is the first BMW Group production site not tied to a specific primary plant. Instead, it serves as a network plant, combining best practices from different locations worldwide. For example, the press shop is modelled on the systems used in Spartanburg (USA) and Swindon (Great Britain), with their know-how and technologies further refined for Debrecen.
At BMW Group Plant Debrecen, the paint shop plays a critical role in significantly reducing the BMW iX3’s CO2e footprint. The production of the new BMW iX3 is expected to generate approximately 80kg CO₂e (scope 1 and 2 emissions) in total.
This figure covers CO₂e emissions from Plant Debrecen, as well as in-house parts production at other BMW Group facilities, including components manufactured in Landshut, for example. This represents a reduction of approximately two-thirds compared to the production of existing BMW derivatives.
Efficient and sustainable
For Plant Debrecen alone, this approach will reduce CO₂e emissions from the manufacture of a vehicle, including its high-voltage battery, by around 90% to about 34 kg CO₂e (when operating at full capacity, compared with other BMW Group facilities).
The complete digitalisation of production processes further boosts assembly efficiency. For example, sensors and camera systems along the production line are used to automate quality control processes.
AI evaluates the data and provides real-time feedback to employees on the assembly line. The building’s “finger structure”, an optimised version of BMW Group Plant Leipzig, allows 80% of parts to be delivered directly to the correct point of assembly on the line. In-house logistics are fully electric.
Hydrogen in Leipzig
Talking of Leipzig, contracts have now been signed with Mitnetz Gas GmbH and Ontras Gastransport GmbH. A 2-kilometre-long link will be constructed by Mitnetz Gas, incorporating a gas pressure and measurement system, which will eventually connect the plant to the future core hydrogen network.
BMW and Ontras are in the process of agreeing on the appropriate connection to the hydrogen grid. The link is expected to start delivering hydrogen to the plant in mid-2027.
Once the pipeline is in place, Plant Leipzig will no longer need hydrogen deliveries by truck, in cylinders. “With supplies coming in via the pipeline, we will be able to use hydrogen in completely new ways, especially for our most energy-intensive processes, such as our curing ovens in the paint shop,” says Petra Peterhänsel, Director of BMW Group Plant Leipzig.
Fuel-flexible burners
In October 2022, Plant Leipzig introduced a fuel-flexible burner in its paint shop, marking another world first in automotive production. Today, it operates a total of eleven such bivalent burners, which are powered flexibly by either gas or hydrogen.
In 2013, Leipzig also introduced hydrogen fuel cell-powered forklifts and tug trains and now operates an intralogistics fleet comprising more than 230 vehicles of this kind – the largest in Europe. They refuel at nine hydrogen refuelling stations located within the plant’s halls.
The core hydrogen network is a nationwide infrastructure project that will consist of approximately 9,000 kilometres of hydrogen pipes. It will go on stream in stages, reaching the whole operation by 2032 and connecting Germany to the transregional hydrogen network.
