Strategic cooperation between Purem by Eberspaecher and Topsoe

- Purem by Eberspaecher supporting Topsoe’s development and production of solid oxide electrolysis cells

- New market segments for the exhaust technology and acoustics specialist


Esslingen (Germany) / Lyngby (Denmark), 18 January 2024 – Purem by Eberspaecher is systematically expanding its portfolio to include solutions for a clean future, especially in the growing hydrogen sector. The strategic partnership between the exhaust specialist and Topsoe is now focused on the production of this energy source. Purem by Eberspaecher provides its expertise in flow control and the handling of corrosive media to support Topsoe’s production of high-efficient electrolysers.

Symbolic signature: The top management of Purem by Eberspaecher and Topsoe, a Danish technology company for catalysis and decarbonization, signed a Letter of Intent in Prague for a strategic cooperation between the two companies. For the exhaust technology and acoustics specialist, this marks an important first step towards entering future market segments.

Holistic approach towards the hydrogen market
For decades, Purem by Eberspaecher has consistently focused its portfolio on the needs of its customers. For the rapidly growing hydrogen market, the company already offers various solutions for both fuel cell systems and the hydrogen engine. However, before hydrogen can be used in a wide range of applications, it must be produced in sufficient quantities – and this is precisely where the industry is currently facing major challenges. Purem by Eberspaecher therefore takes a holistic view of hydrogen and contributes its core competencies to the production of the energy carrier.

Core competencies help industrialize new technologies
The Danish company Topsoe is a global leader in carbon emission reduction technologies and a provider of Power-to-X solutions, i.e. processes that convert green electricity into chemical energy carriers for electricity storage or further use. As part of the strategic collaboration between Purem by Eberspaecher and Topsoe, the exhaust specialist contributes its expertise in flow control and the handling of corrosive media at high temperatures and pressures. Purem by Eberspaecher is thus making a significant contribution to the industrial scaling of the electrolysis process. The goal is to support Topsoe’s development and production of the company’s solid oxide electrolysis cell (SOEC), which generates hydrogen from water with a high degree of efficiency. It consists of several hundred individual cells, which are stacked and connected together. Using the principle of electrolysis, electricity is used to split incoming water vapor into hydrogen and oxygen.

Versatile use of the energy source
High-temperature electrolysis is a relatively new process which that is highly efficient and requires relatively little energy compared to existing technologies. The resulting hydrogen can be used for chemical products and in steel production, for example. Hydrogen also makes an important contribution to clean mobility, as it can be used to produce e-fuels, among other things.
