- Green steel is an environmentally friendly production process in steel making combined with lowering greenhouse gas emissions and perhaps allowing lower cost.
- In fact, blast furnace based steel production in different parts of the world is one of the highest carbon emission sources due to an increased consumption of coal and coke.
- The domestic steel sector within India:
- Approximately 12 per cent of the total GHG emissions in the country are contributed by the steel sector. This emission intensity has remained at about 2.55 tonnes of CO2 per tonne of crude steel.
- Green steel products come fitted with CCS, Network Green/Blue hydrogen, very high biomass utilization, along with artificial iron units that minimise carbon emissions further.
- Indeed, global initiatives now include the First Movers Coalition, the Industrial Deep Decarbonization Initiative (IDDI), SteelZero and ConcreteZero, the European Union, Sweden, and India’s initiative.
- Steel Ministry is formulating the greener steel policy, forming 13 taskforces for determining various modalities around green steel-making.
- India is developing its indigenous pure-hydrogen-based Direct Reduction of Iron (DRI) technology, and ₹455 crore have been sanctioned for piloting hydrogen-based steel making.
