A tech-enabled transformation of the steel sector is underway

The Indian steel sector has undergone a remarkable transformation over the past century, evolving from a single plant in Jamshedpur to becoming the world’s second-largest steel producer. This journey reflects India’s rapid industrialization and its growing prowess in industrial-scale steel manufacturing.

India’s steel industry boasts impressive statistics, with a current national capacity of approximately 125 million tonnes per year. However, the country’s per capita steel consumption of 77 kg remains significantly below the global average, presenting immense growth potential. As the fastest-growing large economy globally, India is poised for transformative changes in its steel sector.

The industry has set an ambitious production capacity target of 300 million tonnes, more than double the current output. This goal, while challenging, opens up exciting opportunities for technological advancements and sustainable practices in steel manufacturing.

 

Decarbonisation: The Steel Sector's Green Challenge

One of the most pressing challenges facing the steel industry is decarbonisation. The steel sector is a significant contributor to greenhouse gas emissions, accounting for 7-9% of global emissions. In response, major steel producers worldwide have committed to becoming carbon-neutral or achieving net-zero emissions by mid-century.

To address this challenge, the industry is exploring various technological solutions:

  1. Alternative Fuel Sources: Steel producers are investigating ways to replace traditional coal and gas-fired power sources with greener alternatives. This includes the integration of solar and wind farms into steel production processes.
  2. Hydrogen in Steel Production: Researchers are experimenting with replacing coke with hydrogen in the blast-furnace process. While hydrogen usage produces only water as a byproduct, scaling this technology to an industrial level remains a challenge due to limited hydrogen availability.
  3. HIsarna Process: This innovative technology eliminates the need for pre-processing raw materials, reducing energy consumption and CO2 emissions by at least 20%. The HIsarna process also significantly decreases emissions of hydrogen, sulphur dioxide, nitrogen, and nitrogen oxide.
  4. Carbon Capture and Utilisation (CCU): Steel plants are implementing CCU facilities using amine-based technology to capture and reuse carbon dioxide on-site. In India, the captured gas with higher calorific value is redirected to the plant’s gas network for more efficient industrial heating.

Circular Economy and Recycled Steel:

The adoption of a circular economy model is crucial for the sustainable transformation of steel production. Recycled steel, combined with green electricity, offers a promising solution for decarbonisation. Ongoing research aims to enable multiple cycles of steel reuse without compromising quality, allowing for increased use of steel scrap in the manufacturing process.

Artificial Intelligence: Revolutionizing Steel Production

Artificial Intelligence (AI) is playing a pivotal role in advancing the steel sector. AI applications are improving various business KPIs, including:

Enhancing yield, throughput, and quality Reducing energy consumption and emissions in mining and manufacturing processes Improving process control through AI-assisted operator decisions 
Implementing predictive models for asset management and equipment failure prevention Leading steel producers, such as Tata Steel, have deployed over 250 AI models across their value chain, delivering critical insights for timely and effective decision-making.

 

Industry 4.0 and the Future of Steel

The adoption of Industry 4.0 technologies is ushering in a new era of steel production. These advancements are enabling:

  1. Hyper-personalized experiences for customers and stakeholders
  2. Improved efficiency and productivity across the supply chain
  3. Enhanced sustainability practices and resource optimization

It’s crucial to recognize the impressive growth of India’s steel sector and its potential for global leadership in iron and steel making technology. The rapid pace of technological innovation in the past two decades suggests an even more accelerated progress in the coming years, particularly in India.

The future of the Indian steel sector looks promising, with a focus on sustainable practices, cutting-edge technologies, and a commitment to meeting the growing demand for steel in an environmentally responsible manner. As India continues to bridge the gap in per capita steel consumption, the industry’s technological advancements will play a pivotal role in shaping a greener and more efficient future for steel production.
