Sustainable Production of Green and Clean Steel

Advantages / Salient Technical Features IPR Status / Details (India/Abroad)
• Single-step process with almost no additional raw • Process knowhow; US Patent and Indian
materials needed Patent
• Absence of unit operations (Pelletisation, sintering,
coke making, desulphurisation, dephosphorisation, Application/Uses
and decarburisation), thus making the process
energy-friendly and cost-effective • The Hydrogen Plasma Smelting Reduction
technology produces 99.54% pure iron,
• Iron ore fines can be fed directly into the Hydrogen which can be used for producing varying
Plasma Smelting Reduuction reactor unlike in grades of steel as an import substitute.
conventional iron making process

Scale of Development
Problem being addressed • Technology demonstration. (Current TRL
• Bringing down the overdependence on non- Level : 04)
renewable resource such as coal
• Minimisation of greenhouse gases emission to the Commercialization Status
environment as there is negligible release of CO and
CO to the atmosphere • Yet to be commercialised
2

Environmental Considerations (if any) Techno-economics
• Lowering the carbon footprint with zero Green House • To be estimated after pilot scale study
Gases emission to the environment
• With no coke ovens and sintering plants required, Technology Package
HPSR process is environmentally friendly • Development of technical flow sheet

Major Raw Materials to be Utilized
• Scope of using iron ore fines
