Green steel - the questions are not ‘ why ?’ and ‘ if ?’, but ‘ when ?’ and ‘ how ?’
Green steel is not a choice , it is the only way forward . However , there are so many decarbonisation pathways open to the iron and steel sector that finding the right solution can be challenging . Many pilots are underway and their lessons will become lighthouses to help operating companies navigate their journey to net-zero .
The questions around green steel are not ‘ if ?’ and ‘ why ?’. Rather the questions are ‘ how ?’, ‘ where ?’ and ‘ when ?’. This article lays out some of the decarbonisation pathways and provides case studies of pilot projects to enable deeper research into the deployment of decarbonisation options to engage in the green steel revolution .

Green steel - the question is not ‘ if ?’, but ‘ how ?’
Steel is the backbone of every industrialized nation . It forms the skeleton of skyscrapers and is the main material used to build ships , buses , cars , trains , and trucks . It is also used to build electricity pylons for the grid and wind turbines that make renewable power . The energy transition cannot take place without steel .
On the other hand , per tonne of product , steel is one of the most carbon-intensive materials used in construction . The chances of finding a cost-effective alternative to steel with a low CO 2 intensity
