HBI: Steel’s Most Versatile Metallic in the Transition to the Hydrogen Economy (Room 201 B)

30 Jun 21
11:00 AM - 11:30 AM

Tracks: Direct Reduced Iron: Use of Alternative Iron Units in Steelmaking

The conversion to hydrogen ironmaking will take time because of the unavailability of green hydrogen at necessary volumes/costs, and the large capital requirements to convert from the blast furnace (BF) to the direct reduction-electric arc furnace route. During this transition phase, other ways to reduce CO2 emissions must be explored in integrated steel plants. Hot briquetted iron (HBI) can be used in the BF/basic oxygen furnace (BOF) to supplement scrap, increase productivity and lower CO2 emissions. Merchant HBI can be produced in large-scale operations at a location where logistics and reducing gas (including hydrogen) can be advantageous and transported in the right amount to existing steelmaking complexes as a flexible metallic source.
