Emission-free energy sources are the future. But in order to achieve this, the combustion process of hydrogen must be improved. In a new project, the Laser Zentrum Hannover e.V. (LZH) is therefore working together with three partners from Lower Saxony on innovative additively manufactured supply components.  

In order to make the production of green hydrogen more efficient, Hanover University of Applied Sciences and Arts (HsH), Leibniz University Hannover (LUH), the Clausthal Centre for Materials Technology (CZM) and the LZH are conducting research into new types of multimaterial components as part of an innovation alliance. For the first time, they want to combine assemblies for particularly low temperatures with those for very high temperatures. This multimaterial design should enable more efficient, more compact and lighter components. Both the mobility sector and decentralised energy supply would benefit from this.

Additively manufactured integrated energy converter

The four partners from Lower Saxony are working together to additively manufacture a functional, integrated energy converter. To this end, they are developing a hydrogen reformer that uses multimaterial components to convert methanol or ammonia into hydrogen. Due to the necessary pressure reduction and high reaction temperatures, high temperature differences occur in one component. It is therefore particularly important that all the materials used, both metallic and ceramic, are well coordinated with each other.

In order to manufacture the components quickly and efficiently, the project partners are developing a process head that can flexibly process both powder and wire base materials. In this way, the partners want to enable a gradual transition between two different materials and thus produce so-called functional-graded materials. The project also includes the characterisation and evaluation of the material systems and components.

About AM2H2

In the innovation network ‘Additive Manufacturing of Multimaterial Components for Sustainable Energy Conversion’ (AM2H2), the CZM is responsible for material development and testing, and characterisation of the materials and components. The LZH is developing laser processes for additive manufacturing, the HsH is conceptualising and manufacturing a process head, while the Institute for Product Development and Device Engineering at the LUH is responsible for simulations and for the construction and design of the system demonstrator. This project is funded by the European Social Fund Plus / European Regional Development Fund.

Laser Zentrum Hannover e.V. (LZH) 
As an independent, non-profit research institute, the Laser Zentrum Hannover e.V. (LZH) stands for innovative research, development, and consulting. Supported by the Lower Saxony Ministry of Economics, Transport, Construction and Digitalization, the LZH is dedicated to selflessly promoting applied research in the field of photonics and laser technology. Founded in 1986, almost 200 employees are now working at the LZH.

The LZH offers solutions to current and future challenges with its smart photonics. Along the process chain, natural scientists and engineers work interdisciplinary together: from component development for specific laser systems or for quantum technologies to process developments for a wide variety of laser applications, for example for medical and agricultural technology or lightweight construction in the automotive sector. 19 successful spin-offs have emerged from the LZH to date. Thus, the LZH creates a strong transfer between fundamental science, application-oriented research, and industry - and uses light for innovation.
