Calix Limited has completed a Front-End Engineering and Design (FEED) study on a hydrogen direct reduced iron (H-DRI) demonstration plant in Australia.
The 30,000 tonne per annum Zero Emissions Steel Technology (ZESTY) H-DRI plant is estimated to produce near-zero emissions hot briquetted iron (HBI) from low grade iron ore for AUD$630-800 ($410-521) per tonne, according to the FEED study.
ZESTY is expected to reduce the emissions intensity of iron ore to metal iron from 1.89 tonnes of CO2 to almost zero, a significant drop as the current reduction process accounts for 80-85% of the steel industry’s emissions.
