Iron and Steel Industry
Iron and steel manufacturing is one of the most energy-intensive industries worldwide. In addition, use of coal as the primary fuel for iron and steel production means that iron and steel production has among the highest carbon dioxide (CO2) emissions of any industry. According to the International Energy Agency (IEA), the iron and steel industry accounts for the largest share — approximately 27 percent — of CO2 emissions from the global manufacturing sector. Annual world steel demand is expected to grow from approximately 1,410 million tonnes (Mt) of crude steel in 2010 to approximately 2,200 Mt in 2050. The bulk of this growth will take place in China, India, and other developing countries in Asia. This significant increase in steel consumption and production will drive a significant increase in the industry’s absolute energy use and CO2 emissions.
In China the iron and steel industry accounted for around 27 percent of primary energy consumption of Chinese manufacturing in 2010. The iron and steel industry, as a pillar industry for Chinese economic development, has grown rapidly along with the national economy. The crude steel production in 1996 exceeded more than 100 Mt. Since then, steel production in China has continued to increase rapidly, and China has been the world’s largest crude steel producer for 16 continuous years. China represented 47% of the world steel production in 2010. For this reason, the development path of China’s iron and steel sector will greatly affect future energy demand and dynamics in China.
