Results of Hydrogen Reduction Trial y g
H2 reduction increased in both COG injection from the blast tuyeres andreformed COG injection from the shaft tuyeres because of the fast reactionrate of H2 reduction.・Carbon direct reduction decreased which is a huge endothermic reaction;・Carbon direct reduction decreased, which is a huge endothermic reaction;this is the main reason for the reduction in carbon input.

Concluding Remarks
COURSE50 aims at developing new drastic CO2 reduction technologies.The CO2 emissions reduction target is approximately 30% in the steel works.
The project aims to achieve this reduction through iron ore reduction byThe project aims to achieve this reduction through iron ore reduction byusing coke oven gas (hydrogen resource containing) to suppress CO2 emissions From blast furnaces, in combination with separation and recovery of CO2from blast furnace gas by using unused waste heat in the steel works.
The project completed the development of the basic technologies in STEP 1The project completed the development of the basic technologies in STEP 1(2008-2012) according to schedule, and is now engaged in the developmentof the comprehensive technologies in STEP 2 (2013-2017).
The goal of the project is to establish the CO2 reduction technologies whichcontribute technically to commercialize the first unit by around 2030contribute technically to commercialize the first unit by around 2030and to generalize the technologies by 2050, considering the timing of thereplacement of blast furnace equipment.
