Nobian Enhances Frankfurt Site's Energy Efficiency with Flexible Production

Key highlights
  • Chlor-alkali electrolysis at Höchst adjusts production based on electricity availability.
  • Next Kraftwerke collaborates on the transition with a virtual power plant.
  • Production is planned one to two days in advance, with real-time adjustments possible.
  • All Nobian electrolysis plants in Germany now operate in energy-optimized mode.

Flexible Production for Energy Efficiency

Nobian's chlor-alkali electrolysis at the Höchst Industrial Park now adjusts production based on electricity availability in the German grid. This flexibility allows the site to reduce production during low electricity availability and increase it when availability is high, contributing to grid stability and optimizing energy consumption.

Collaboration with Next Kraftwerke

The transition to flexible production was achieved in collaboration with Next Kraftwerke, which operates a virtual power plant connecting electricity producers, consumers, and storage systems. Production is typically planned one to two days in advance, based on electricity price forecasts and customer order flexibility.

Real-Time Adjustments and Safety

Production flexibility is enhanced by the E-Flex mode, allowing real-time reactions to electricity price spikes. During high demand, production can be temporarily reduced, with storage supplementing missing quantities. Automation supports flexible model switching, reducing energy costs while maintaining full operational control and safety standards.

Expansion to Other Sites

The chlor-alkali electrolysers at Nobian's Ibbenbüren and Bitterfeld sites have also been converted to energy-optimized mode. This means all Nobian electrolysis plants in Germany now operate flexibly, contributing to the energy transition.
