Progress continued at the Energiepark Bad Lauchstädt throughout April and May. As part of the phased commissioning, important technical tests are being carried out – with a particular focus on electrolysis.
Progress on the Electrolysis Plant
Work on the three electrolysis modules continues to proceed according to schedule. The modules form the heart of hydrogen production: Here, water is split into hydrogen and oxygen using electricity generated from renewable energy sources.
An important step currently underway is the so-called “hot tensioning,” which has now begun on the first two modules. This is a specialized technical process in which certain bolted connections and components are readjusted in a controlled manner under realistic temperature conditions. This ensures that the plant will remain permanently leak-free and stable during subsequent operation.
The water treatment plant is also making further progress. It ensures that high-purity water is available for electrolysis—an important prerequisite for the safe and efficient operation of the plant. The 600-hour test run currently underway is designed to evaluate the systems over an extended period under real-world conditions.
Expansion of the security infrastructure
Further measures were also implemented in the area of infrastructure. For example, VNG Gasspeicher GmbH has begun erecting additional camera towers. The video surveillance system is designed to secure the construction site and help ensure safe operations during the ongoing construction and commissioning phases.
Hydrogen pipeline remains stable under operating gas pressure
The future hydrogen pipeline to the refinery will remain filled with hydrogen. This process, known as “preservation” under hydrogen, protects the pipeline while also allowing for ongoing testing.
Regular sampling continues to show stable trends: The hydrogen concentration in the pipeline is stabilizing as expected. The measurements thus once again confirm the safe operating condition of the converted infrastructure—an important step toward the future transport of green hydrogen to Leuna.
