Purem by Eberspächer is diving headfirst into the world of green hydrogen, showing off its very first SOEC (Solid Oxide Electrolysis Cell) pressure vessels at its Neunkirchen, Germany facility on June 5, 2025. These vessels, built in partnership with Topsoe, are at the heart of Topsoe’s cutting-edge hydrogen production systems. So what makes them a big deal? Thanks to SOEC technology, which operates at high temperatures to split steam into hydrogen and oxygen, the process uses less electricity—making it both efficient and cost-savvy compared to other methods.
A Big Pivot for a Traditional Player
This marks a serious shift for Purem, which has traditionally focused on automotive exhaust systems. But like many companies with their eye on the future, they’re thinking bigger—and greener. To make the leap, Purem retrained its workforce, secured specialized certifications, and laid out plans to start full-on production by the end of 2025. With support from local officials, this bold move shows how legacy manufacturers are reinventing themselves to stay relevant in the fast-changing landscape of sustainable energy.
Powering Europe’s Hydrogen Future
The launch doesn’t just boost Purem’s portfolio—it strengthens Topsoe’s supply chain and helps root next-gen hydrogen tech manufacturing right in the heart of Europe. This joint push is nudging green hydrogen even closer to being rolled out on a truly industrial scale. It’s a clear signal that industrial decarbonization is gaining momentum, and it’s happening now.
