Salzgitter Group and VNG expand cooperation in using hydrogen as alternative energy source


Further feasibility study initiated: Focus on hydrogen supply options for Salzgitter as a centre of industrial production

VNG AG and Salzgitter AG will jointly test the use of climate-neutral hydrogen and biomethane for steel production at the Salzgitter Flachstahl GmbH steel plant in Salzgitter, Lower Saxony. Gunnar Groebler, Chairman of the Executive Board of Salzgitter AG, and Hans-Joachim Polk, Member of the Executive Board for Infrastructure & Technology at VNG, signed a corresponding memorandum of understanding in Salzgitter. 

The aim of the partnership is to create a study on options for supplying steel production facilities in Salzgitter with hydrogen as an alternative energy source. The analysis includes options of on-site electrolysis and supply via non-pipeline hydrogen derivatives such as ammonia or methanol (e.g. via rail tanker), which will be used to meet at least part of the energy requirements in a transitional phase. In addition, the focus is on existing plans for a long-term connection to a supraregional hydrogen network, which will transport large volumes of hydrogen from various generation regions and projects to the site. 

With the joint feasibility study, Salzgitter and VNG are continuing and deepening their successful partnership in use of hydrogen. In the summer of 2020, the two companies announced that they were cooperating in the area of green gases. A memorandum of understanding was signed at that stage, after which two feasibility studies on climate-friendly hydrogen supply and on hydrogen transport were carried out.

“The development of the hydrogen economy is a prerequisite for reducing CO2 emissions in industry. For this reason, we are pleased to be able to continue our strong partnership with Salzgitter with this joint analysis and thus pave the way towards a climate-friendly hydrogen supply for the steel mill at the Salzgitter site,” says Hans-Joachim Polk.

Gunnar Groebler, comments as follows: “The hydrogen supply to the steel mill is one of the main pillars of our SALCOS® transformation programme. Having already taken a fundamental look at the subject in the form of a study with our partners from the Hydrogen Campus Salzgitter, I look forward to further concretisation together with VNG."
