Hisarna
HIsarna is a technology based on bath-smelting. It combines coal preheating and partial pyrolysis in a reactor, a melting cyclone for ore melting and a smelter vessel for final ore reduction and iron production. It requires significantly less coal usage. Furthermore, it is a flexible process that allows partial substitution of coal by biomass, natural gas or even Hydrogen(H2).

HisarnaCosts & Benefits
| Parent Process: Smelting Reduction | |
|---|---|
| Energy Savings Potential |
Hisarna technology opens the opportunity of 20% improvement in steel industry energy efficiency. |
| CO2 Emission Reduction Potential |
20 % reduction of CO2/t-hot rolled coil (HRC) without carbon capture and storage (CCS) is expected. Morevoer, reduction of upto 80% in CO2/t HRC is possible with CCS. |
| Costs |
Investment and/or operational costs are not available because the technology is still in research. |
