BTU will be at InnoTrans 2026!

InnoTrans is the leading international trade fair for Transport Technology, held every two years in Berlin. Divided into five exhibition segments – Railway Technology, Railway Infrastructure, Public Transport, Interiors and Tunnel Construction – InnoTrans occupies all 42 halls of the Berlin Exhibition Centre. The InnoTrans Convention, the event’s high-calibre supporting programme, complements the trade fair and is streamed live. A unique feature is the InnoTrans track and outdoor area, with 3,500 metres of track, showcasing everything from tank wagons to high-speed trains.

At the Berlin-Brandenburg joint stand, the SpreeTec neXt research consortium and the Production Administration chair will present innovative research on additive manufacturing: from metal- and polymer-based processes and rapid tooling to novel material developments and repair strategies. Laser- and arc-based technologies for hydrogen applications highlight our focus on sustainable energy solutions. In addition, we are presenting AI-based approaches to the planning and management of maintenance orders. 

Come and visit us to discover technologies that are already shaping the production of tomorrow.

To mark its 25th anniversary, E‑world energy & water at Messe Essen was bigger and better than ever before. Over 37,000 trade visitors attended Europe’s leading trade fair for Energy Economics. A total of 1,136 exhibitors showcased their solutions for the energy supply sector. Key topics included the energy transition in conjunction with security of supply, as well as the potential applications of new storage technologies and artificial intelligence. BTU Cottbus-Senftenberg was once again represented with a stand at the joint stand of the Berlin-Brandenburg capital region and presented the Cottbus Energy Innovation Centre (EIZ).

The trade fair appearance significantly raised the profile of the EIZ. The fair was viewed as a design challenge – not only in terms of visibility but also regarding its impact on the ecosystem. Small-scale trials of new ideas were carried out, many new contacts with companies were established, and interesting discussions took place on current developments, innovations and challenges surrounding the energy transition, which are also of benefit to the BTU as a whole. For the first time, partner interviews were conducted live on site.

The EIZSpark start-up team BARQ, which optimises energy in electric vehicle fleets, used the fair to raise its profile and was able to sign its first start-up agreement at the event.

We would like to thank all participants, stand visitors and organisers, and look forward to E-world 2027!

Once again, BTU successfully showcased its work at InterBattery, the international trade fair dedicated to batteries, in Seoul (South Korea). The Physical Chemistry chair, in collaboration with the ReLioS network, showcased BTU’s expertise in the recycling and recovery of battery materials and raw materials from lithium-ion batteries at the joint stand of the Berlin-Brandenburg capital region. The stand was visited by, amongst others, trade visitors from recycling companies, material producers and processors. Contacts with companies, the regional Chamber of Foreign Trade, TechnoParks and chambers of commerce were expanded. The profile of BTU’s research activities was significantly raised through our presence at the fair. We would like to thank all participants, stand visitors and organisers, and look forward to InterBattery 2027!

The “Lausitz Science Park” (LSP) project has had a successful showing at HANNOVER MESSE 2026. From 20 to 24 April, the LSP exhibited for the first time at the joint stand of the Brandenburg Economic Development Corporation (WFBB) and, together with its partners, showcased the innovative strength of the Lausitz region on the international stage.

Under the motto “Home for Innovation”, the LSP presented research projects, initiatives, start-ups and companies that are already closely linked to the emerging science and technology park in Cottbus. The focus was on forward-looking solutions in the fields of the energy transition, sensor technology, sustainable industrial processes and innovative mobility – key themes for one of Germany’s most dynamic regions undergoing structural change. A highlight: the visit to the joint stand by Brandenburg’s Minister for Economic Affairs, Martina Klement, Berlin’s State Secretary for Economic Affairs, Severin Fischer, and WFBB Manager Sebastian Saule.

The presenting partners included 

• the DLR Institute for Low-Carbon Industrial Processes at the German Aerospace Centre,
• chesco GmbH,
• Negus CB GmbH,
• Gas-Grün-Solution GmbH,
• NMI Technologies,
• SpreeTec neXt,
• Berlin-Lausitz Innovation Corridor,
• Net Zero Valley Lausitz.

This year, BTU Cottbus-Senftenberg was represented at AERO Friedrichshafen 2026 – Europe’s leading trade fair for general aviation. From 22 to 25 April, the exhibition centre on Lake Constance once again became a hub for innovation, exchange and forward-looking technologies in the field of sustainable aviation.

BTU presented itself for the first time with the SpreeTec neXt project. At the joint stand of the Berlin-Brandenburg Capital Region (Hall A5, Stand 301), the team showcased innovative solutions and exhibits from metal- and plastic-based manufacturing processes for the aviation industry.

The presentation was a resounding success: inspiring discussions, interesting talks, new contacts and exciting ideas.

Particular highlights at our stand included:

• the presentation of an ultra-lightweight drone with AI-supported visual reconnaissance as an example of forward-looking, additively manufactured aerospace systems
• the technical presentation by Carlos Saunders on rapid thermal simulation in large-scale additive manufacturing
• in-depth technical discussions with industry representatives on specific use cases and potential for collaboration
• the keen interest in additive manufacturing technologies, lightweight construction concepts and new material systems
• the strong exchange within the Berlin-Brandenburg capital region and the joint visibility of innovative research 

We would like to thank all participants, stand visitors and organisers.
