5、efficient power storage technologyMore efficient renewable energy technologiesAs a result,hydrogen-based processes are unlikely to be implemented before 2035 except in regions that already have a lot of low C footprint energy available Scandinavia,Canada412/02/20254Scrap as a De-Carbonization Lever1

6、00%scrap-based operations utilizing EAF technology already have a very low CO2 footprintFootprint can be lowered through improvements in efficiency and Fe yieldMust understand the properties of scrap to optimize its Value-in-useIncreasing levels of scrap residuals(Cu,Sn,Ni,Mo)are a concern and will
