The project, supported by a dedicated group of Luxembourg investors and years of close cooperation with the national authorities, represents a total investment of $300 million and is scheduled for phased commissioning between 2028 and 2030. Once fully operational, the center will create more than 300 high-skilled jobs and serve as a European hub for advanced materials research and development.
Founded in 2010 and headquartered in Leudelange, Luxembourg, OCSiAl is currently the leading global producer of single-wall carbon nanotubes (also known as graphene nanotubes). These nanomaterials significantly enhance mechanical strength, electrical and thermal conductivity, and other properties of composites. The company’s existing production is located in Serbia, where capacity is being quadrupled, while its nanotubes are already incorporated in over 10 percent of smartphones sold worldwide and in more than one million electric vehicles.
Alain Kinsch, member of the OCSiAl board of directors, stated: “Graphene nanotubes can improve over half of the materials we use every day, from safer batteries to longer-lasting tires and ultralight protective equipment. 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.”
The new Differdange facility will substantially increase global supply of graphene nanotubes, reinforce Europe’s position in the advanced materials supply chain, and support the growing demand from industries ranging from automotive and energy storage to electronics and aerospace. By establishing large-scale production in the heart of Europe, OCSiAl aims to accelerate the adoption of these transformative nanomaterials across multiple sectors while contributing to regional economic development through technology transfer and job creation.
The project underscores Luxembourg’s continued commitment to attracting high-value manufacturing and innovation-driven enterprises, positioning the country as a key location for next-generation materials that enable lighter, stronger, and more efficient products.
