View of the future of steelworks through the use of hydrogen: development of possible scenarios for optimal use and networking of locations
The plant in Hamburg paves the way for a hydrogen-based future.
Think about tomorrow today
A principle that can be applied to many areas of life. At ArcelorMittal, looking into the future means dealing with innovations, planning investments, and estimating operating costs – all with the idea of successfully implementing the energy transition. To develop possible scenarios, ArcelorMittal is planning the joint research project WiSaNo (wind steel from northern Germany) together with the Hamburg University of Applied Sciences.
The starting point for the project is the planned hydrogen-based steel production. High amounts of energy are required for the implementation and the largest expansion of renewable energies is possible in the North and Baltic Sea areas through offshore wind farms. An innovative unit consisting of a wind farm and steel mill has great potential for use. This opens up diverse opportunities for the structurally weak north.
In a first preliminary investigation, different variants are to be considered in order to produce one million tons of steel per year. For each variant, an estimate of the required wind farm size, the investment costs, and the production costs for steel should be determined. A variant is, for example, a wind farm with a reduction system near the coast coupled with a steel mill at an existing location. The sponge iron in the form of hot-briquetted iron is transported by rail or ship through Germany. The existing infrastructure can be used there and additional investments can be avoided. Another variant would be to create the wind farm and steel mill completely near the coast: The steel produced in this way is almost free of CO2 emissions, but the construction is associated with high investments. It is already clear here that each scenario has certain advantages and disadvantages. A total of five variants are to be illuminated by summer 2020.
In the event of follow-up financing, the second project phase follows. The focus is then on the intensive investigation of the relationship between the wind farm and the steelworks and the development of detailed simulation models. ArcelorMittal sees the research project as a great opportunity. The results can significantly optimize future planning. The project application for review is currently submitted to the Ministry of the Environment.
