• About 89% of a BF-BOF's energy input comes from coal, 7% from electricity, 3% from natural gas and 1% from other gases and sources. In the case of the EAF route, the energy input from coal accounts for 11%, from electricity 50%, from natural gas 38% and 1% from other sources.5 FACT SHEET Energy use in the steel industry
Coal is currently a major source of fuel for power generation, industrial heat, and, on a smaller scale, manufacture of coke and by-product coal tar. In the mid to long-term, anticipated increases in the cost of natural gas and petroleum relative to coal are expected to increase the incentive for ...
