Purem by Eberspaecher has unveiled its first assembled Solid Oxide Electrolyzer Cell (SOEC) pressure vessels at its Neunkirchen facility, marking a major milestone in its strategic partnership with Topsoe, a global leader in advanced technologies for the energy transition. This collaboration highlights Purem’s growing role in the green hydrogen economy, as it supports the production of Topsoe’s high-efficiency SOEC technology—a key enabler for sustainable hydrogen generation.
Under the partnership, Purem by Eberspaecher is responsible for both manufacturing and assembling critical pressure vessels used in SOEC systems. These vessels are central to the electrolyzer’s function, where water vapor is converted into hydrogen and oxygen using high-temperature electrolysis. This method offers significantly higher efficiency and lower energy consumption compared to conventional electrolysis technologies.
The newly showcased vessels, revealed during a ceremony in early June, demonstrate the success of a manufacturing concept co-developed by both companies, tailored for future large-scale production. The event was attended by Topsoe leadership and Jürgen Barke, Minister of Economic Affairs for Saarland, underscoring the regional and strategic significance of the partnership.
“We’ve developed a strong electrolysis technology to support the global transition to green hydrogen,” said Kim Hedegaard, CEO of Power-to-X at Topsoe. “Collaborating with Purem by Eberspaecher strengthens our supply chain with their extensive industrial know-how.”
Purem by Eberspaecher, traditionally known for exhaust and acoustic solutions, is expanding its capabilities to meet emerging energy demands. In preparation for SOEC production, the company has trained specialized personnel in welding techniques and initiated certifications outside the automotive sector to ensure compliance with hydrogen-industry standards. Series production is slated to begin at the Saarland plant by the end of 2025.
“We are actively reshaping our business to meet future demands,” stated Benjamin Brenkel, Executive Vice President and Head of Business Unit Europe at Purem by Eberspaecher. “This partnership demonstrates our shift toward sustainable technologies and our ability to deliver in new, high-growth markets.”
Background on SOEC Technology
Solid Oxide Electrolyzer Cells (SOEC) use electricity and heat to convert water vapor into hydrogen and oxygen—an efficient method with broad applications. The green hydrogen produced can be used in chemical manufacturing, steel production, and the creation of e-fuels for mobility, supporting decarbonization across industries.
With this collaboration, Purem by Eberspaecher reinforces its commitment to innovation and sustainability, joining Topsoe in shaping the future of clean energy through scalable hydrogen solutions.
