All of Nobian’s chlor-alkali electrolysis plants in Germany (at the Frankfurt , Ibbenbüren and Bitterfeld sites) now have the capabilities to produce flexibly to optimize their power use – aligned with the supply in the German electricity grid. When availability is low, for example due to fluctuations in wind or solar energy, production can be reduced. When more electricity is available, production can be increased accordingly. This helps stabilize the power grid while reducing energy consumption. 

The transition was made in cooperation with Next Kraftwerke, operator of a virtual power plant that intelligently connects electricity producers, consumers, and storage systems. Data from numerous sources are used to coordinate supply and demand – forming the basis for Nobian’s production planning. 

Production is usually planned to the hour one or two days in advance – depending on the price forecast and the flexibility of customer orders. Production flexibility is even further increased by using the so-called E-Flex mode: This allows the plant to react in real time to current electricity price spikes. During high demand, production can be temporarily reduced, and missing quantities are supplemented from storage. Throughout the whole process, production safety is our top priority: Safe and reliable supply to our customers must be ensured at all times. We maintain full operational control, ensuring automation never compromises our safety standards. 

This flexibility enables Nobian to produce more when green energy is abundant and reduce consumption during shortages. Thus, we actively contribute to the energy transition – in line with our sustainability mission Grow Greener Together. 

Nobian’s goal is to become climate neutral by 2040 – ahead of the targets set by the Paris Climate Agreement. With the conversion of all electrolysis plants, Nobian is well positioned to use energy more efficiently while ensuring supply security for its customers.
