Avacon

Avacon, a member of the E.ON Group, operates seven newly built wind turbines with an output totaling 30 megawatts on the premises of Salzgitter AG. Salzgitter Flachstahl GmbH has installed two Siemens 1.25 megawatt PEM electrolyzer units on its plant site that are capable of producing around 450 m an hour of ultra pure hydrogen. Today's steel production already harnesses hydrogen for annealing processes as well as in the hot dip galvanizing lines. Industrial gas producer Linde is currently delivering gas by truck and will continue to secure coverage of hydrogen requirements in the future as well. A test run is currently being made of all the facilities. With "WindH2", the partners intend to gather the know-how and experience from the on-site production of wind power and hydrogen, as well as their integration into the complex workflows and processes of an integrated steelworks. The cost of the entire project - building the wind turbines and the hydrogen plants, including integrating them into the existing supply network - amounts to around EUR € 50 million. The construction of the electrolyzer was subsidized by KfW.
