EOS Joins Hydrogen Materials Consortium to 3D Print for the Energy Transition

EOS has joined the MAT-H2 consortium, a collaborative effort to develop materials and manufacturing processes suited for hydrogen energy applications. The initiative is led by Finnish companies and research institutions, with Wärtsilä's WISE program at its core.

What the consortium is building

MAT-H2 brings together industrial players including EOS, Neste, Nordic Tank, Teknos, SSAB, Bumax, SP Stainless, and Wärtsilä, alongside research partners VTT and the University of Oulu. The goal is to close the gap between laboratory research and real-world hydrogen infrastructure.

Hydrogen environments are tough on metals. High pressure, extreme temperatures, and embrittlement risks mean standard alloys often fail. Additive manufacturing offers a path to test new alloy compositions and optimized geometries faster than conventional forging or casting.

EOS's specific role

EOS will contribute its metal powder development and process engineering know-how. The company has built its reputation on qualifying specific material sets for its DMLS and SLM systems, and that experience maps directly onto hydrogen-tolerant alloy development.

Paula Kainu, EOS Industrial Manager Energy, said additive manufacturing lets the consortium develop, test, and optimize materials with greater speed and flexibility than traditional trial-and-error methods.

Why this matters for 3D printing

Hydrogen is a cornerstone of most decarbonization roadmaps. If MAT-H2 succeeds, the material specifications and printing parameters developed here could become industry standards. That would open a significant new market for industrial metal 3D printers and the engineering teams behind them.

The consortium is Business Finland-funded, meaning European public money is effectively betting that additive manufacturing is the fastest route to viable hydrogen components. EOS is the first major metal AM original equipment manufacturer to publicly align with this specific hydrogen cluster.
