A review on low carbon emissions projects of steel industry in the World

Abstract In the context of global climate change, greenhouse gas emissions have become increasingly serious. Steel companies make a great contribution to the annual CO2 emissions, making this industry one of the key contributors to climate change. Many countries are paying high attention to the emission reduction technologies in the steel industry, and a trend has been established focusing on the reform and innovative changes of steel companies. Amidst this backdrop, the methods and technologies in the World regarding energy saving and emission reductions are reviewed in the article. Moreover, this article also selected projects like the COURSE50 project in Japan, the FINEX-CEM project in Korea, the hydrogen metallurgy projects in China, the ULCOS project in Europe, the ‘H2 Future’ project in Austria, the HYBRIT project in Sweden, the Carbon2Chem and SALCOS projects in Germany, molten oxide electrolysis and hydrogen flash smelting project in the US, to optimize the current metallurgical industry and to display the development direction and progresses that have been made. The existing projects investigate the coke substitution and treatment of by-product gases, and the technology symbolizing the future development trends of the metallurgical industry, which is the cutting-edge research at this time.
