Steel is one of the most commonly used metal materials in global industry over the past two centuries, and its presence can be seen in almost all infrastructure, especially key components. As a typical traditional industry, the steel industry not only plays an extremely important role in the development process of modern industrial society, but also creates a large number of direct employment opportunities. As the core foundation of China’s industrial industry, the steel industry has made irreplaceable contributions to the vigorous development of the national economy.
However, in recent years, traditional steel enterprises have increasingly faced various challenges in their production and operation processes, such as complex production processes, increased links and equipment, redundant data, and high carbon emissions. This has led to a decrease in production energy efficiency and increased environmental pressure, while also limiting the automation, informatization, intelligence, and green level of steel enterprises. According to data from the World Iron and Steel Association, the greenhouse gas emissions generated by the steel industry during production account for nearly 8% of the total, ranking second among all emission sources, only behind the power generation industry.
Under the background of “dual carbon”, green development of the industrial chain has become a trend of the times, and more and more traditional and mature industries are prioritizing sustainable development, including the steel industry. Developing appropriate decarbonization plans, combined with innovative digital technologies and advanced green and low-carbon technologies, is increasingly becoming a “problem-solving path” for various industries. Among them, steel enterprises should play a leading role by accelerating their own digital and green low-carbon dual transformation, recasting their core competitiveness, and strengthening close cooperation with upstream and downstream enterprises to jointly promote the entire industry chain to accelerate its transformation towards high-end, intelligent, and green, ultimately achieving net zero emissions.
Seize the five new technological opportunities and promote the comprehensive development of green steel
The traditional blast furnace steelmaking technology requires the use of a large amount of coke to produce refined steel products. This production process was widely regarded as highly economical for a long time in the past, but in reality, it lacks a “green gene”. With the increasing call for green environmental protection and sustainable development in society, green steel products have gradually become a breakthrough point and business growth point for steel enterprises and upstream and downstream industrial chains.
New technological innovation has brought development opportunities for green steel. Leading steel companies in the industry are anchoring their “dual carbon” goals and actively exploring the application scenarios of new technologies. From establishing pilot factories to verify new technologies and production methods, to conducting relevant employee training, they will take five specific measures to promote their greenhouse gas emission reduction goals. Among them:
Shift from traditional coal to using biomass as a reducing agent and fuel
Optimize blast furnace (BOF) efficiency, reduce production energy consumption and process losses
Adopting a more environmentally friendly electric arc furnace (EAF) to increase the recycling rate of scrap steel
Utilizing carbon capture technology to improve the recycling efficiency of carbon in chemical industry production
Improve technologies with low environmental impact, such as hydrogen based direct reduction of iron, to promote their large-scale commercial application
This series of measures aimed at carbon reduction and decarbonization will help the steel industry reduce its own carbon footprint, and with the continuous innovation and iteration of technology, especially high-tech such as direct reduction of iron, it will also bring more significant green benefits. In addition, based on the opportunities brought by new technologies, enterprises can also collaborate with upstream and downstream partners in the industrial chain to build a large-scale green steel ecosystem in a more scientific and economical way.
In addition to breakthroughs in decarbonization technology, steel companies have also become increasingly aware that in order to further improve production efficiency, optimize decision-making efficiency, and enhance business resilience, they need to use interconnected products to efficiently manage their own production processes, and break through data silos through advanced software platforms to unleash data value. In addition, the key to transitioning from “traditional” to digital, green, and low-carbon is the need for professional and applicable full lifecycle solutions and services from top-level planning to implementation.
