Q. With reference to Green Steel, consider the following statements;
1.It is steel which is manufactured without the use of fossil fuels.
2.Direct electrification through electrolysis of iron ore can produce green steel.
Which of the statements given above is/are correct?
Statement 1 is correct: It is steel which is manufactured without the use of fossil fuels. This can be done by using low-carbon energy sources such as hydrogen, coal gasification, or electricity.
Statement 2 is correct: In order to decarbonise the iron and steel sector, the primary emphasis through technological interventions would be on substituting the primary production processes with cleaner alternatives. Such as, 1) Carbon capture, utilisation and storage (CCUS), 2) Replacing conventional sources of energy with low-carbon hydrogen, and 3) Direct electrification through electrolysis of iron ore.
