Steelmaking process employing hydrogen produced by a very high temperature reactor and the scale of the plant

Kasahara, Seiji ; Kubo, Shinji ; Inagaki, Yoshiyuki; Ogawa, Masuro

Outline was discussed for very high temperature reactors (VHTRs), IS process for hydrogen production and hydrogen steelmaking process integrated with them. Hydrogen of 7.0710 $^{6}$ Nm $^{3}$ /d was produced and electricity of 497 MW was generated using 5 VHTRs of 600 MW thermal output to produce steel of 110 $^{4}$ t/d, similar scale to a conventional blast furnace (BF) plant. A significant reduction of CO $_{2}$ emission to 13% of that from a BF plant was expected by the hydrogen steelmaking plant. Sensitivity analysis of steelmaking cost on hydrogen production cost showed that the hydrogen production cost of 3.0 US/kg-H $_{2}$ was required for the lower steelmaking cost than conventional steelmaking processes.
