Topic: CO₂ Breakthrough Program by COURSE50 in Japanese Steel Industry Sector

Abstract

Since FY2008, four Japanese blast furnace steelmakers and one engineering company have been working on the CO ₂ Ultimate Reduction in Steelmaking Process by Innovative Technology for Cool Earth 50 (COURSE50) project, which is one of the national projects commissioned by the New Energy and Industrial Technology Development Organization of Japan, aimed at developing powerful new CO₂ emission mitigation technologies for steelworks. The goal is to mitigate those emissions in the steelmaking process by approximately 30 % under the precondition of establishment of economic rationality of the process and availability of CCS infrastructure. This is done through a technology that reduces iron ore using hydrogen-amplified coke oven gas to curb CO₂ emissions from blast furnaces and that separates and recovers CO₂ from blast furnace gas using unused exhaust heat from steelworks. In this chapter, an overview of the COURSE50 project is provided.
