The analysis, based on data from LeadIT’s Green Steel Tracker, focuses on decarbonizing steel production in the EU by examining the renewable energy and renewable hydrogen demands for iron reduction and primary steel production. The transition to green iron and steel production will require a significant increase in demand for renewable electricity, especially for the production of renewable hydrogen. The analysis considered two scenarios: one without the use of scrap in steel production and the other with a 50% share of scrap. Both scenarios explored two routes for green steel production: one with an EU-based value chain and another relying on iron sourced from outside the EU. Key findings from the analysis include the estimation that up to 135 terawatt hours of renewable energy would be needed annually if all announced green iron and steel projects in the EU by 2045 were to rely on renewable electricity and not use scrap. Moreover, it was projected that green hydrogen demand could reach 1.9 million tonnes per annum by 2045, covering a significant portion of today's steel production. The analysis also highlighted the potential energy savings if EU companies were to import hot briquetted iron (HBI) instead of domestically producing green hydrogen and direct-reduced iron without scrap. This would reduce the renewable energy requirements significantly. The study emphasizes that transparent planning by both the EU and steel producers is essential to ensure the successful transition to renewable electricity-based steel production. It also mentions the importance of assessing the feasibility of projects, realistic timelines, and supply infrastructure to meet demand at competitive prices, especially regarding the development of renewable energy and green hydrogen prices.
