The steel industry in Japan has already achieved the worldfs top-level energy efficiency by making persistent efforts for energy saving, through which contributing to CO2 reduction as one of the countermeasures for global warming. Technology development is the key to responding to requests for further reduction of CO2 on a global scale, and drastic steps by innovative technologies are deemed indispensable in the long term.
In the initiative gCool Earth 50h announced by the then Prime Minister Shinzo Abe in May 2007, proposed was the achievement of compatibility between environmental protection and economic growth through the utilization of energy-saving technologies and the like. To accomplish this aim, an initiative gCOURSE 50h or gCO2 Ultimate Reduction in Steelmaking Process by Innovative Technology for Cool Earth 50h was established and positioned as one of the gInnovative Technology Developmenth.
COURSE 50 aims at developing technologies to reduce CO2 emissions by approximately 30% through suppression of CO2 emissions from blast furnaces as well as capture - separation and recovery - of CO2 from blast furnace gas (BFG), and establishing the technologies by ca. 2030 with the final goal of industrializing and transferring the developed technologies by 2050.
The second step of NEDO* project - gEnvironmentally Harmonized Steelmaking Process Technology Development.h is now in progress (2013 - 2017) (*New Energy and Industrial Technology Development Organization)
