Lanxess has plans to use hydrogen to power a spray dryer facility at its Krefeld-Uerdingen site in Germany. With this, the spray dryer facility will become one of the first large-scale industrial plants in the country to use hydrogen as a fuel in continuous operation.

Cologne/Germany – Lanxess is making its production at the Krefeld-Uerdingen site more sustainable. The specialty chemicals company will use hydrogen instead of natural gas to dry its iron oxide pigments. This will make the spray dryer one of the first large-scale industrial plants in Germany to use hydrogen as a fuel in continuous operation. Lanxess will thereby reduce its carbon footprint by about 6,000 metric tons per year.

The hydrogen is produced during chlorine electrolysis at the neighboring Covestro plant and transported directly to the Lanxess plant via a pipeline.

“Switching from a natural gas burner to a hydrogen burner is a significant technological step towards low-greenhouse-gas processes,” says Michael Ertl, Head of the Inorganic Pigments business unit at Lanxess. “We are proving that decarbonizing industry works not only in pilot projects, but also in the day-to-day operation of large production facilities.”

Lanxess installed the hydrogen burner at the end of 2025 and has gradually brought it online since then. The system is designed to be powered entirely by hydrogen. Technical integration includes a dedicated hydrogen line, an adapted burner, and measurement control technology, as well as additional safety and control systems.

Verbund Site as a Key Success Factor

“The project shows that industrial partners at a Verbund site can particularly successfully shape the transition to climate-friendly production,” says Rob Eek, Production Manager at Covestro in Krefeld-Uerdingen. The Verbund site’s close integration is the basis for this success: short pipeline routes, shared infrastructure, and established safety concepts ensure a reliable hydrogen supply.

Lanxess and Covestro have a long-standing partnership at the Krefeld-Uerdingen site. Covestro supplies nitrobenzene, which Lanxess uses to produce its iron oxide pigments. Aniline is produced as a byproduct of this process, which is then returned to Covestro as an important raw material for plastics production. The recently implemented use of hydrogen in the spray dryer adds an additional climate-relevant component to the established production partnership.
