A Green Gateway for Gloomy Global Steelmaking

The global steel industry, a cornerstone of modern infrastructure, faces a profound environmental reckoning, responsible for approximately 7–9% of direct fossil fuel emissions. India, as the world’s second-largest steel producer since 2018, holds an outsized portion of this burden, industrial carbon emissions from steelmaking contributing 10% to 12% of the nation’s total CO₂ output. Traditional blast furnaces, reliant on coal-based coke, produce steel with a heavy carbon footprint, exceeding 2.5 metric tons of CO₂ per metric ton of steel. Against this challenging backdrop, a significant partnership emerges. Tata Steel Limited, a titan of Indian industry, inaugurated its first scrap-based electric arc furnace (EAF) facility in Ludhiana, Punjab, in March 2026. Built with an investment of approximately ₹3,200 crore (roughly $3.85 billion USD based on current exchange rates), this pioneering plant has a capacity of 0.75 million metric tons per annum. The facility is engineered to limit CO₂ emissions to under 0.3 metric tons per metric ton of steel, a 90% reduction compared to conventional methods, while operating on nearly 50% renewable energy. Commencing operations soon after, INOX Air Products Private Limited, a leading Indian manufacturer of industrial & medical gases, commissioned a 280 metric tons per day cryogenic air separation unit (ASU) at this very location. The ASU provides a continuous on-site supply of high-purity oxygen, nitrogen, argon, gases serving a sine qua non for advanced EAF steelmaking. As N Chandrasekaran, Chairman of Tata Steel, stated, the facility reflects “Tata Group’s long-term commitment to building a greener, more resilient industrial future”.

Oxygen, Nitrogen, Argon, an Orchestrated Onslaught

The heart of this technological advancement lies within the newly commissioned air separation unit. The 280 metric tons per day cryogenic ASU, a fully automated system, extracts atmospheric gases through a process of compression, cooling, & fractional distillation. In an EAF, high-purity oxygen accelerates the scrap melting process, boosting productivity while reducing electrical energy consumption. Gaseous nitrogen serves multiple critical roles, creating protective, inert atmospheres inside the furnace void to prevent unwanted reactions & strengthen specific steel products. Argon functions as a primary inert shielding gas during the refining & decarburisation phases, effectively removing excess carbon from the molten metal. Mike Walsh, an independent industrial analyst focused on materials processing, explains, “The precise injection of argon is absolutely essential for producing high-grade steel grades free from inclusions. Without it, achieving consistent, premium quality in a scrap-based furnace becomes exponentially more difficult.” The ASU’s design also provides strategic supply chain flexibility. Beyond serving Tata Steel’s immediate needs, the agreement permits INOX Air Products to distribute surplus gas output to other industrial consumers across the northern Punjab region. This arrangement reduces upstream delivery timelines & fortifies localised gas supply chains for an entire manufacturing ecosystem. Siddharth Jain, Managing Director of INOX Air Products, emphasised the dual significance: “The commissioning of this 280 TPD cryogenic ASU is a proud milestone for INOXAP, both in terms of our engineering capabilities & our commitment to enabling some of India’s most ambitious industrial projects... this ASU intends to open up a strategic gateway for liquid gas distribution across northern India”.

Blast Furnaces Besieged, a Bold Bypass

The Ludhiana EAF signifies a strategic departure from the carbon-intensive blast furnace-basic oxygen furnace (BF-BOF) route that has traditionally dominated Indian steelmaking. Rather than using virgin iron ore & coking coal, the EAF process melts 100% steel scrap using substantial electrical power, drastically reducing the need for raw material extraction & cutting emissions at the source. The Ludhiana plant sources approximately 40% of its ferrous scrap from Tata Steel’s own recycling facility in Rohtak, Haryana, creating a closed-loop, circular economy model where obsolete products transform into new construction-grade steel rebar under the Tata Tiscon brand. This shift is a direct acknowledgment of India’s rising scrap availability & a pressing need to curb the heavy pollution associated with the BF-BOF method. Currently, India’s rapid industrialisation & infrastructure growth make it a significant global hot spot for steel capacity expansion. According to Global Energy Monitor, the nation is now responsible for over two-fifths of global steelmaking capacity in development. The chairman of Tata Steel, N Chandrasekaran, noted that out of the company's total 35 million metric tons of steel capacity, 25 million metric tons are in India, with plans to add another 6.5 million metric tons. T V Narendran, Chief Executive Officer & Managing Director of Tata Steel, reinforced this view, stating, “The Ludhiana EAF marks a defining milestone in Tata Steel’s journey towards achieving Net Zero by 2045. It reflects how Tata Steel is rethinking capital investment for a circular economy, by backing technologies that reduce resource intensity while remaining globally competitive”.

Corporate Collaboration, a Crucial Catalyst

The seamless integration of INOX Air Products’ ASU at the Tata Steel mill exemplifies a crucial industrial collaboration model, one where on-site gas supply partnerships facilitate the adoption of complex new technologies. For Tata Steel, commissioning a dedicated, high-capacity ASU would have required significant capital expenditure, operational expertise, & diversion of focus from its core steelmaking activities. Outsourcing this function to a specialised gas company like INOXAP allows Tata Steel to access mission-critical gases at predictable costs without upfront investments. The fully automated nature of the unit also ensures an uninterrupted supply, a critical reliability factor for continuous steel production. This partnership positions INOX Air Products as more than just a vendor, it makes them an integral component of Tata Steel’s production infrastructure. For its part, INOX Air Products strengthens its operational footprint in northern India, expanding liquid gas distribution capabilities for oxygen, nitrogen, & argon across a region hungry for industrial expansion. This symbiotic relationship reduces the risks inherent in pioneering green technologies. It also creates economies of scale, allowing the ASU to serve not just one major anchor customer but also a network of smaller manufacturers nearby through tanker supplies, reducing lead times & improving supply chain efficiency. The agreement is structured to permit INOX to supply output to third-party industrial consumers across the region, maximising asset utilisation & reinforcing regional supply chains. This collaborative framework could serve as a blueprint for future greenfield industrial projects across India, where manufacturing processes are increasingly specialised & interdependent.

Scrap’s Supreme Surge, Shifting Sourcing Strategies

The transition toward EAFs places scrap steel at the centre of India’s low-carbon future. This Ludhiana plant is designed to use 100% steel scrap as its raw material. As the nation accelerates its net-zero ambitions, the demand for high-quality ferrous scrap is projected to skyrocket. Unlike traditional blast furnaces, which are dependent on consistent supplies of iron ore, an EAF’s feedstock flexibility is both its strength & its vulnerability. While recycling steel drastically lowers carbon emissions, it depends on robust, organised scrap collection & processing infrastructure. Tata Steel has been proactive in this arena, the company operating a state-of-the-art steel recycling plant in Rohtak, Haryana, which directly supplies roughly 40% of the scrap required by the Ludhiana mill. To secure its feedstock further, the company has been building a dedicated scrap supply chain through initiatives like Tata FerroBaling, a project focused on processing & baling scrap from various sources. The company aims to scale up its steelmaking capacity to 40 million metric tons by 2030 in India, & as part of its sustainability push, Tata Steel plans for 10 to 15 million metric tons of that production to come through the recycling route within the next decade. This ambition aligns with India’s national goals. The government has recently notified a formal taxonomy for what constitutes “green steel” in India, defining it as finished steel carbon emissions of less than 2.2 metric tons per metric ton. The Ludhiana facility far exceeds this national benchmark, setting a new standard for domestic sustainable manufacturing. The plant’s ability to use nearly 50% renewable energy further reduces its reliance on the coal-heavy national grid.

Funding a Futuristic, Frugal Forge

The scale of investment underscores the serious financial commitment required for the green industrial transition, both from corporate balance sheets & from public infrastructure support. Tata Steel’s commitment of approximately ₹3,200 crore (or roughly 3.85 billion USD) for a 0.75 million metric ton facility represents a premium over traditional BF-BOF capacity of similar size. However, this investment calculus must account for future regulatory risks related to carbon taxes, border adjustment mechanisms, & the growing commercial demand for low-CO₂ steel from environmentally conscious automakers & construction firms. Concurrently, INOX Air Products is also signalling significant financial momentum. In March 2026, Reuters reported that the industrial gas maker is planning to launch a 1 billion initial public offering (IPO) on the Mumbai stock exchange, appointing Kotak, JPMorgan, & Citi to manage the offering. The company, a joint venture between American industrial gas multinational Air Products & Chemicals & India’s INOX Group, operates nearly 50 locations across India, produces over 4,200 metric tons per day of liquid gases, & serves more than 1,800 customers across 18 industries. In the financial year ending March 2025, INOX Air Products recorded revenues of 11 billion in 2023, is projected to rise to 21 billion by 2030[reference:26]. The funding could be directed toward building more on-site ASUs & electronic specialty gas hubs, such as the Rs 500 crore (roughly 60 million USD) facility INOX announced in Dholera, Gujarat, to support India’s emerging semiconductor industry.

A Role Model Replicability, Regions & Release

The successful commissioning of the Ludhiana EAF & its supporting ASU is not intended as an isolated event. Top executives have signalled that this project will serve as a “role model” to be replicated across four or five other suitable locations in India. During the inauguration ceremony, N Chandrasekaran noted that in the United Kingdom, 3 million metric tons of steel capacity is being converted to green steel, while in Europe, efforts are underway to transition 7 million metric tons of capacity over the next decade. The key challenge for India is that while it is also increasing total capacity, the green transition is not uniform. This disparity creates a dual domestic market, one where high-emission steel will likely become cheaper to produce but potentially subject to penalties & another where low-emission, premium-grade steel can command higher prices & access more lucrative export markets. Creating such a role model facility in a historically overlooked region like Ludhiana is also strategically significant for industrial geography. It helps deconcentrate heavy industrial development away from traditional coastal clusters, distributing economic benefits to interior states. The plant will deliver long-term community benefits, partnering with local Industrial Training Institutes for employability training, introducing new livelihoods for women, installing solar-powered streetlights, & building community-based waste management systems. As other industrial giants, perhaps in the automotive or defence sectors, look to decarbonise their own supply chains, the Ludhiana blueprint, combining a scrap-based EAF, on-site industrial gas supply, & a foundation of renewable energy, provides a tangible, investable pathway for a lower-carbon heavy manufacturing future within a rapidly industrialising nation.
