Salzgitter AG and Uniper SE have signed a pre-contract for the supply and purchase of green H₂. This is to be produced in the large-scale electrolysis plant planned by Uniper, which is scheduled to be commissioned in Wilhelmshaven in 2028. The green H₂ will be required for the SALCOS - Salzgitter Low CO₂ Steelmaking program and will be used in the direct reduction plant being constructed in Salzgitter to produce almost CO₂-neutral steel. In this way, both companies want to make a significant contribution to reducing the CO₂ footprint of the German steel industry.

The preliminary agreement covers, among other things, the technical and commercial framework conditions for the supply of H₂. Depending in particular on the availability of the German H₂ core network and a specific pipeline route from Wilhelmshaven to Salzgitter, Uniper could supply up to 20,000 tons of certified green H₂ to Salzgitter every year starting 2028 at the earliest. This will be produced using renewable energies in the 200-MW electrolysis plant that Uniper plans to build on the site of the former hard coal-fired power plant in Wilhelmshaven. This is the first step towards an external H₂ supply for SALCOS, which will require up to 150,000 tpy of H₂ in its first stage. A pipeline connection from Wilhelmshaven to Salzgitter is absolutely essential and must be established as quickly as possible. The pipeline operators and political decision-makers, together with Salzgitter AG and Uniper SE, urgently need to agree on an accelerated timetable for this.

Gunnar Groebler, CEO of Salzgitter AG said, “With SALCOS, we are a pioneer in the decarbonization of raw materials industry. From the beginning, we have relied on a network of strong partners to implement the program. The production and availability of green H₂ is a key success criteria for SALCOS. This agreement with Uniper is therefore another important step on our path to green steel. The energy infrastructure and the associated power grids now urgently need to be expanded.”

Holger Kreetz, COO of Uniper said, “At Uniper, we pursue the clear goal of supporting companies in the decarbonization of their production processes. Green H₂ plays a crucial role in this - especially in energy-intensive industries such as the steel industry. We look forward to working with Salzgitter AG and helping to reduce Salzgitter AG's emissions. Such partnerships demonstrate the added value of our Energy Transformation Hub Northwest, strengthen the region's role as an energy hub for the future and make a valuable contribution to achieving Germany's climate targets together.”

Wilhelmshaven is the ideal location for Unipers Green Wilhelmshaven projects due to its easy access to renewable energies, particularly from the offshore wind farms in the North Sea, the early connection to the German H₂ pipeline system, and the planned H₂ storage facilities in northern Germany. The plan is to expand electrolysis to a capacity of 1 GW, which will enable H₂ production of 100,000 tpy. In addition, Uniper will build a terminal in Wilhelmshaven for the import of green ammonia by ship with an output volume of at least 300,000 t of H₂, which can be converted into H₂ and also fed into the German nuclear grid.
