Sector-coupling Green Hydrogen for Steel Production – Power grid support and sustainable mobility

Important results from the project

The project´s primary goals were achieved. The project analyzed operational data from the electrolyzer system and refined the models by incorporating actual operational experience. The project presented a techno-economic and environmental assessment of hydrogen production, including several scenarios. Key operational and cost parameters obtained were integrated into the optimization model, enhancing the alignment of refueling station behavior with industrial hydrogen use.

Expected long term effects

The models and optimization frameworks that have been developed will contribute to an efficient integration of large hydrogen systems in the steel and transport sectors. The insights gained, such as optimal electrolyzer sizing, revenue-stacking strategies, have provided a foundation for more economical hydrogen operations. The collaboration with industry has strengthened the path toward a full system demonstrator and enables future deployment of hydrogen-powered heavy trucks.

Approach and implementation

The project was divided into three areas of analysis: technical-economic performance of hydrogen production in a steel mill, development of an optimization model for electrical market participation to minimize the total cost based on system operation, and development of a model to predict the operating cost and study the feasibility of hydrogen production with a hydrogen refueling station. The project was carried out in a research team at KTH, with continuous interaction with the partners.
