EOS joins EU-funded MAT-H2 consortium to research hydrogen-resistant metal AM materials with Finnish industrial partners

EOS has joined the EU-funded MAT-H2 consortium, a Finland-centered research group studying how metals, coatings, and manufacturing processes hold up in hydrogen environments. Fellow members include coatings firm Teknos, fastener maker Bumax, Spstainless, steelmaker SSAB, engine group Wartsila, researcher VTT, Nordic Tank, and the University of Oulu. The consortium's stated goal is components that resist long-term hydrogen exposure without losing strength, a challenge tied to hydrogen embrittlement in stainless steel, nickel, and titanium alloys. Wartsila's WISE energy group, covering hydrogen power plants, power trains, and production, is a named application target EOS will support with metal LPBF and materials expertise.

The project extends EOS's laser powder bed fusion technology, originally developed by Olli Nyrhila's team in Finland, into a materials-qualification effort rather than a commercial product launch. For EOS, it is a low-cost way to build early data on hydrogen-service alloys such as 316L stainless steel ahead of any industrial-scale build-out of European hydrogen infrastructure. Materials characterization for embrittlement resistance sits squarely in the qualification work that determines which AM suppliers get specified into new energy programs, so early involvement gives EOS a reference point in a vertical where PBF-LB suppliers currently have little qualified data.
