Iron and steel industry breeds huge energy saving wealth

February 27, 2019

The China iron and steel industry energy saving low carbon development report (2018), 2012-2016, the world steel association member unit of the average index of comprehensive energy consumption of per ton steel in the overall upward trend, while our country electric steel ratio and Europe and the United States, Japan and South Korea compared to the traditional steel powers such as low proportion serious, the average index of comprehensive energy consumption of per ton steel in our country and abroad index compared to the average comprehensive energy consumption of per ton steel in structure with gap is huge.According to the production process by country in 2017, the proportion of electric furnace steel in Europe, the United States, India and other countries accounts for about 60%, other Asian countries account for 20-30%, only China accounts for about 9%.

According to the change trend of comprehensive energy consumption per ton of steel in China's iron and steel enterprises, the comprehensive energy consumption per ton of steel in China's key large and medium-sized iron and steel enterprises decreased to 570.5kgce/t in 2017, down 2.6% year on year.The crude steel output increased by 2.9% compared with 2016, and the total energy consumption increased by about 0.3%.Due to the influence of technological progress and management improvement, the energy consumption index of tonnage steel in China has decreased.In 2017 and 2016, the main production processes showed a downward trend. The energy consumption of coking process decreased slightly, down 0.04%; the energy consumption of sintering process decreased 2.77%; the energy consumption of iron smelting process decreased 1.48%; the energy consumption of converter steelmaking process increased 0.03%; the energy consumption of electric furnace steelmaking process decreased 0.06%; and the energy consumption of rolling process increased 0.03%.Nevertheless, China's iron and steel industry still has problems in energy conservation: one is that the energy structure that emphasizes energy efficiency has become the most important issue.Second, it is difficult to innovate energy-saving technologies, and technological energy conservation has encountered bottlenecks.Third, the importance attached to energy conservation is still insufficient and the level of energy management urgently needs to be improved.Fourth, the lack of long-term energy saving mechanism.Fifth, the distortion of energy consumption statistics of iron and steel enterprises is obvious, which brings difficulties to the statistical, analysis and prediction of energy conservation in the industry.

Steel industry is an important industry of carbon emission

China's iron and steel industry energy saving and low-carbon development report (2018) points out that China is currently facing the situation of energy saving and low-carbon: first, China is facing more stringent "dual control" assessment.In China's 13th five-year plan, the country's GDP of 10,000 yuan and total energy consumption were assessed on the basis of "dual control". Energy consumption per unit of GDP decreased by 15% compared with 2015, and the total energy consumption was controlled to 5 billion tons of standard coal.In 2017, the national development and reform commission released the "dual control" assessment results of provinces and cities across the country, showing that liaoning, ningxia and xinjiang provinces and regions have not completed.Second, China's green manufacturing system will be fully established in the 13th five-year plan.In 2020, China's green manufacturing system will be fully established, with 100 green parks, 1,000 green factories and 10,000 green products forming the main content of the green manufacturing system.Third, ultra-low emissions require steel enterprises to control energy consumption from the source.In the past two years, China's developed regions and provinces with large energy consumption are under great pressure.Fourth, the national carbon market is about to be established, and steel enterprises are facing practical pressure.

In December 2017, China launched the national carbon market, which is divided into three stages: infrastructure construction, simulation operation and deepening improvement.Among them, take electric power as the breakthrough point to take the lead in conducting transactions, and gradually expand the coverage scope in accordance with the principle of "mature an industry into an industry".At present, national carbon emission trading has gradually covered eight key industries, including petrochemical, chemical, building materials, steel, non-ferrous metals, paper making, electric power and aviation.

China's iron and steel industry energy conservation and low-carbon development report (2018) believes that the iron and steel industry is an important industry in carbon emission and one of the first eight key emission industries included in the national carbon emission trading market. The iron and steel industry will gradually become the main force in the carbon market.Li xinchuang estimated that the total energy consumption of the steel industry increased by only 8.9 percent year-on-year in 2018, when the output of the industry increased by 11.0 percent.In 2019, the total energy consumption of the steel industry decreased by 3.4% year on year while the output decreased by 2.4%.In 2018, the average comprehensive energy consumption per ton of steel in the steel industry decreased by 1.84% year on year.In 2019, the average comprehensive energy consumption per ton of steel in the steel industry decreased by 0.89% year on year.

Li stressed that China's iron and steel industry is at a critical stage of promoting the carbon market, and accelerating the establishment of a unified national carbon market for the iron and steel industry is the focus of the next step.In particular, it is pointed out that the establishment of carbon trading market does not affect enterprises' assessment indicators, but that enterprises need to take "real money" to buy quotas in the market if they fail to meet the quota, and enterprises will face real cost pressure.According to the development experience of carbon market in other countries and regions in the world, steel enterprises as participants should focus on the following aspects: collecting carbon data, storing carbon technology, paying attention to carbon trading, accounting carbon cost and exploring carbon potential.
