Green hydrogen produced at Uniper and VNG’s German facility
In Germany, at the Energiepark Bad Lauchstädt, Green Hydrogen has been produced in the 30-megawatt electrolysis plant for the first time. The electrolysis plant, jointly operated by Uniper and VNG Handel & Vertrieb GmbH (VNG H&V), is the heart of the hydrogen production process: it uses renewable electricity from the connected wind farm to split water into hydrogen and oxygen. The Energiepark is now entering the phase in which the components of the overall system will be tested together. This brings the planned industrial use of Green Hydrogen, set to begin in 2027, one step closer.
The pressurized alkaline electrolyzer consists of three modules, each with a capacity of ten megawatts. Each module comprises two so-called stacks, where the electrochemical conversion of water into hydrogen and oxygen takes place.
Construction of the large-scale electrolyzer began with the official groundbreaking in June 2023. With the first hydrogen production now underway, a decisive stage has begun on the path toward integrated operation of the Energiepark: the technical foundation for hydrogen production has been established, and the focus now shifts to the interaction with the other components of the value chain.
Uniper and VNG H&V jointly manage the construction and operation of the large-scale electrolysis plant through their joint venture, Elektrolyse Mitteldeutschland GmbH (EMG). Uniper contributes its international experience in developing hydrogen projects along the entire value chain. With its expertise in wholesale gas trading, VNG H&V is responsible for marketing the hydrogen produced at the Energiepark, thereby supporting the development of trading and sales structures for this new energy carrier.
