Energy Transformation Hub Northwest

Combining sustainability and security of supply to ensure the energy supply of the future at the Energy Transformation Hub Northwest.

Uniper is concentrating its major projects in northern Germany at the Energy Transformation Hub Nordwest (ETHNw). The company is aiming to build a comprehensive hydrogen infrastructure that includes the production, transport, storage and utilisation of green hydrogen. By 2030, capacities are to be created here that will enable the production of up to 1 million tonnes of green hydrogen per year.

The Energy Transformation Hub Northwest represents a significant step towards a low-carbon economy. In addition to hydrogen production, renewable energies such as wind and solar energy are also to be further expanded.

LNG terminal in Wilhelmshaven

Greater independence and supply security for Germany. The first landing terminal for LNG in Germany, to be set up as a Floating Storage & Regasification Unit (FSRU), will be built in Wilhelmshaven at the Umschlagsanlage Voslapper Groden (UVG) transhipment complex pier. Uniper will build and operate the terminal with support of the Federal Government of Germany. Uniper's goal is independence from individual energy sources and a sustainable energy future. This way Uniper considerably contributes to diversifying the energy imports of the Federal Republic of Germany.

Green Wilhelmshaven

Today, the German port of Wilhelmshaven is an important centre for the import of coal and oil. Its potential for green energy carriers has yet to be realized. The Green Wilhelmshaven project will establish an energy hub for the large-scale import and production of green hydrogen. With Green Wilhelmshaven, we will help ensure the security of supply of Hydrogen products in Germany and large parts of continental Europe. Furthermore, this large-scale project will also ensure value-adding in the region both my creating new jobs in the area and by driving the energy transition in Germany – and Europe – forward.

Large-scale electrolysis

Uniper plans to build and operate a large-scale industrial electrolysis plant on the site of the former coal-fired power station. In its final expansion stage, this plant will have an output of one gigawatt, which will enable the annual production of around 100,000 tonnes of hydrogen. The electrolysis will be powered exclusively by renewable energy, utilising Wilhelmshaven's good connection to the offshore wind farms in the German North Sea. The green hydrogen produced in Wilhelmshaven will be available to customers throughout Germany in future. The development of hydrogen logistics, including the connection of Wilhelmshaven to the German H2 network and access to H2 storage facilities, is crucial for this.

H2-Importterminal

Low-carbon hydrogen in the form of ammonia can be delivered via the import terminal in Wilhelmshaven using large tankers. The focus is on ‘cracking’ the delivered ammonia, in which it is split into hydrogen and nitrogen. Thanks to the connection to the planned hydrogen core network, the hydrogen can be fed in directly, transported to the regions where it is needed or temporarily stored in caverns.

The project is currently in the preparatory phase, in which the design principles and engineering basis are being created. Questions regarding commercial development and authorisation procedures are also being clarified in this phase.

Chess – Using wind power to produce green hydrogen

Uniper is planning to build a 30 MW electrolysis plant at the Elsfleth-Huntorf site that will supply green hydrogen. The water supply has already been secured and the authorisation for the plant is currently being prepared. This project serves as a blueprint for a cost-effective plant concept for further Uniper hydrogen projects and represents a pioneering project to enable the transformation at the Elsfleth-Huntorf site.

Solarpark Voslapper Groden

A photovoltaic plant with a capacity of around 17 MWp is to be built on the site of the former ash landfill of the decommissioned Uniper coal-fired power plant in Wilhelmshaven. The solar park will cover an area of around 14 hectares and comprise around 30,000 solar modules. This plant will generate around 17,000 MWh of renewable electricity per year and can thus supply up to 4,500 households.

Krummhörn – Hydrogen in natural gas storage

The HPC Krummhörn project aims to test the construction and operation of a 100% hydrogen storage facility under real conditions. During the test operation, Uniper is testing equipment, materials and materials for H2 compatibility and gathering experience regarding the technology and operation of hydrogen storage. We are using our salt cavern storage facility in Krummhörn in northern Germany, which has not been in commercial use since 2017, for this purpose. The demonstration plant is scheduled to go into operation in 2025.

Training center – Acquiring the know-how for the jobs of the future

One of the basic prerequisites for successfully shaping the energy transition is well-trained specialist personnel. At our training center at the Wilhelmshaven site, we promote the training and upskilling of specialists in hydrogen-related occupational fields. Together with partner companies, we also offer internships at universities or training courses, for example in the field of pneumatic control technology.
