Hydrogen Technology World Expo: Fraunhofer ILT Showcases Laser Technology for the Hydrogen Value Chain

At the Hydrogen Technology World Expo 2026 in Hamburg, the Fraunhofer Institute for Laser Technology ILT will demonstrate how laser technology can be used at various stages of the hydrogen economy. From October 20 to 22, 2026, researchers from Aachen will present solutions for electrolysis, fuel cells, Power-to-X, and hydrogen storage.

The focus is on laser-based manufacturing processes designed to produce parts and components for hydrogen applications more efficiently and to tailor them functionally. The spectrum ranges from the industrial production of membrane electrode assemblies and bipolar plates to processes for electrolysis technologies.

Protective Coatings and Joining Processes

Another key area of focus is underground hydrogen storage. As part of the European HyCavern project, Fraunhofer ILT is working on new approaches to permanently protect steel linings against the effects of hydrogen. To this end, laser-based protective coatings and joining processes are being developed to improve the durability of the materials used.

Material behavior and joining technology are particularly crucial for hydrogen storage and transportation. Laser processes can help apply coatings precisely and create reproducible joints. This is especially relevant for applications in which components are exposed to high stresses over the long term.

Manufacturing for Hydrogen Applications

In addition, the institute highlights work being conducted in its own Hydrogen Lab. There, in collaboration with project partners and companies, laser-based manufacturing processes for hydrogen technology are being developed. The goal is to translate research findings into industrial processes and thereby support the scaling of corresponding components.

At the trade show, Fraunhofer ILT will demonstrate the role that laser technology can play not only in individual process steps but also along the entire hydrogen value chain. In the field of surface technology, protective coatings, material-appropriate joining processes, and the precise machining of functional components are of particular importance.
