OCSiAl has announced the signing of a land lease that launches the development of its flagship graphene nanotube production center in Differdange, Luxembourg. The new site will become the world’s largest graphene nanotube manufacturing facility. The announcement follows an investment round from Luxembourg-based investors and the company’s agreement with the State of Luxembourg for a long-term lease on a 3.63-hectare site.

“This future production center in Differdange perfectly illustrates our ambition to position Luxembourg as a key player in industrial innovation in Europe. This major investment in graphene nanotubes demonstrates investors’ confidence in our ecosystem and highlights the potential of our business parks to host high-tech industrial projects. We are proud to support OCSiAl in this strategic step, which will contribute to the creation of skilled jobs, the reputation of Luxembourg in deep-tech, and the transition to a more sustainable and competitive industry,” said Lex Delles, minister of the economy, SME, energy and tourism.

“OCSiAl’s investment highlights Luxembourg’s role as a platform for long-term innovation and smart industrial development,” said Gilles Roth, minister of finance. “This project reflects the value of combining private sector vision with public infrastructure support.”

Founded in Luxembourg in 2010, OCSiAl has grown into the world’s largest producer of graphene nanotubes, a next-generation material that enhances the performance of a wide range of products used daily. The company’s nanotubes, currently produced only in Serbia where capacity is increasing fourfold, are used in more than 10 percent of smartphones sold today and in over one million electric vehicles worldwide.

“Graphene nanotubes can improve over half of the materials we use every day, from safer batteries to longer-lasting tires and ultralight protective equipment,” said Alain Kinsch, a member of the OCSiAl board of directors. “We thank the Luxembourg Government for enabling this project through the land lease and for fostering an environment where innovation and industrial ambition can thrive.”

“This is a landmark step for OCSiAl and for Differdange,” said Norbert Becker, another OCSiAl board member. “It’s a project that combines visionary science, strong local roots, and a long-term investment in jobs and know-how.”

With a planned investment of $300 million and the creation of more than 300 new jobs, the facility will be launched in stages from 2028 to 2030. The project will strengthen Europe’s presence in the global advanced materials value chain and serve as a development hub for future engineers and scientists.
