Industry Overview Global Steel Industry

The global steel industry recorded another year of subdued growth during CY2025, due to weak construction activity, uneven manufacturing recovery, persistent geopolitical tensions and evolving trade policies that posed constraints upon steel demand across major economies. Global crude steel production remained largely stable at an approximation of 1.85 billion tonnes, reflecting softer demand conditions despite resilient output in select emerging markets.6

China remained the worlds largest steel producer, accounting for over half of global crude steel production with approximately 960.81 million tonnes in CY2025. However, persistent downturn in the real estate market and moderating infrastructure activity constrained domestic steel demand, thereby, resulting in exports surpassing 119 million tonnes. Elevated exports heightened pricing pressures in international markets, while the Organisation for Economic Co-operation and Development (OECD) estimates that global excess steelmaking capacity may exceed 680 million tonnes over the medium term.7

Steel production across Japan, South Korea and Europe remained subdued amidst constrained automotive production, sluggish industrial activity, rising energy expenditure and softer construction demand. In the United States, higher interest rates and decelerating industrial investments moderated steel consumption, reflecting uneven rebound across the developed economies.

Additionally, ongoing geopolitical tensions, supply-chain disruptions and raw material price volatility persistently pose uncertainty across global steel markets. Despite near-term challenges arising from global overcapacity, trade protectionism and geopolitical instability, long-term steel demand is anticipated to remain supported by infrastructure investments, renewable energy, transportation, urbanisation and manufacturing expansion across EMDEs. Moreover, the global transition towards low-carbon infrastructure and clean energy is forecasted to unlock fresh business prospects within the premium steel segment.

CONSERVATION OF ENERGY, TECHNOLOGY ABSORPTION, FOREIGN EXCHANGE EARNINGS AND OUTGO UNDER COMPANIES ACT, 2013

A) Introduction

In a world of rising energy demand and environmental constraints, energy conservation and efficiency represents the most practical and immediate opportunity to align economic growth with long-term sustainability.

Energy efficiency is not merely a technical or operational improvement—it is a strategic pillar of economic development. By lowering costs, enhancing competitiveness, conserving resources, and supporting sustainability, it enables economies to achieve higher growth with lower energy intensity.

Energy conservation contributes to GDP growth in three ways, viz, productivity gains, opportunity for reinvestment and facilitates job creation: This is why energy efficiency is often called a "hidden fuel."

Energy Conservation leads to lowering of energy use, contributing to reduced CO2 emissions, easier compliance with ESG and carbon norms and lower exposure to carbon pricing mechanisms

Energy efficiency accounts for approximately 40% of the possibility of reducing greenhouse gases and helps in overcoming the critical challenge of mitigating climate change while maintaining economic growth.

B) Steel Sector

Steel production is highly energy intensive. Sophisticated energy management systems ensure efficient use and recovery of energy throughout the steel-making process for use within the steel works.

Energy efficiency in an integrated steel plant is central to cost competitiveness, operational stability, and long-term sustainability. Energy efficiency is one of the most effective ways to reduce CO2 emissions and there is a compelling need today to effectively reduce the CO2 intensity. Given the energy-intensive nature of the blast furnace-basic oxygen furnace (BF-BOF) route, even small improvements in energy performance translate into substantial financial and environmental gains.

Energy efficiency in an integrated steel plant is therefore far more than a cost-saving measure—it is a strategic driver of profitability, sustainability, and competitiveness

Energy consumption in an integrated steel plant is dependent on the following: -

• Process route (BF-BOF Vs EAF)

• State of Art Technology

• Quality of Raw materials (ash in coal, Al2o3/ SiO2 in iron ore and fines etc.)

• Level of deployment Energy Conservation & Energy Efficiency Technology

• Process management

• Energy mix

• Scale of operation.

C) Process Management

In an integrated steel plant, around 50-55% of total energy is consumed in blast furnace process and around 70-80% energy is utilized in up to iron making. Reduction of fuel rate in Blast Furnace is the single most important factor for reducing cost and energy consumption. Reduction of fuel rate depends on quality of coke, quality of iron ore in terms of alumina, usage of sinter, adiabatic flame temperature etc.

The other measures for reduction in energy consumption are:

i) Blending of various coals to maintain CSR and CRI in coke production,

ii) Maintaining optimum AL2O3/SiO2 ratio in Sinter,

iii) Ensuring low % of micro fines in Iron Ore fines,

iv) Ensuring around 75-80% Sinter in Blast Furnace burden,

v) Burden distribution in Blast Furnaces,

vi) Controlling Blast Humidification,

vii) Oxygen enrichment in Blast,

viii) Combined blowing in Steel making process,

ix) Use of thin slab continuous caster in casting,

x) Adoption of Cleaner Energy Efficient Technologies.

NMDC Steel Limited has given a lot of importance in adoption of energy efficiency technology. In the design stage, it has adopted the best technology from global reputed technology suppliers along with their Indian consortium partners.
