Periodic Reporting for period 1 - RecHycle (Recycling renewable hydrogen for climate neutrality)
Reporting period: 2022-06-01 to 2023-11-30
ArcelorMittal has recently investigated and determined the potential use of other sustainable fuels and reducing agents, both on-site and provided by an external produce.The study of the operational limits of the BF-B in Ghent was carried out by AMMR using a heat and mass balance model. The necessary permits of the site implementation of the proposed solutions have been obtained. The operational limits of the furnace were analysed in relation to several scenarios.The materials that will be used at hydrogen rich environments are currently being tested for the risk of hydrogen embrittlement. Room temperature testing of one material has shown no mechanical weakening due to hydrogen exposure.In order to ensure and guarantee the smooth and safe operation of all the demonstrations taking place in the RecHycle project, an action plan is prepared and presented. The RecHycle project's Life Cycle Assessment (LCA) and Life Cycle Cost (LCC), following ISO 14040 standards, focuses on environmental impacts in the steel industry. Key impact categories like global warming, acidification, and water consumption are currently being studied. The analysis encompasses the entire steelmaking process, comparing the current "AS-IS" scenario with a future "TO-BE" scenario that includes a hydrogen hub.
