Additively manufactured multi-material components for efficient hydrogen production

Emission-free energy sources are central to the future energy supply. In order to increase efficiency in the production of green hydrogen, the Laser Zentrum Hannover e.V. (LZH), Hannover University of Applied Sciences and Arts (HsH), Leibniz Universität Hannover (LUH) and the Clausthal Center for Materials Technology (CZM) are cooperating in a joint project. The aim is to develop new types of multi-material components using additive manufacturing in order to optimize supply components.

The project focuses on the additive production of an integrated energy converter that can efficiently convert methanol or ammonia into hydrogen. The aim is to develop components that can cope with extreme temperature differences within a single system. By combining materials that can withstand both very low and very high temperatures, a more compact and lighter design is to be realized. This could be particularly beneficial for the mobility sector and decentralized energy supply.

A key aspect of the project is the development of a flexible process head for additive manufacturing. This should be able to process both powdered and wire-shaped starting materials. This will enable a gradual transition between different materials, leading to the production of functionally graded materials (FGM). These materials have varying properties within a component and are particularly suitable for applications with high thermal loads.

In addition to the actual production, the comprehensive characterization and evaluation of the developed material systems is also a central component of the project. The knowledge gained should help to further advance the additive manufacturing of multi-material components and enable new applications in energy generation.

Finally, this project could make an important contribution to improving hydrogen production and thus represent a step towards sustainable and emission-free energy sources.
