SMS Group’s first plant in India with novel coke oven gas (COG) injection technology reduces coke consumption and CO2 emissions, supporting India’s emission reduction to net zero by 2070.
Tata Steel Meramandali in the Indian state of Odisha has taken a major step towards decarbonizing its production by awarding SMS Group a contract for the modernization and installation of Paul Wurth COG injection technology at Blast Furnace #1. Coke oven gas is a by-product of the production of coke from coal in coking plants. The project is the first of its kind in India and represents a significant milestone on the road to more sustainable steel production.
Paul Wurth’s COG injection technology is a development to reduce coke consumption and thus the CO2 “footprint” of blast furnace operation. By utilizing the chemical potential of coke oven gas (COG), the new process can save around 0.65 kilograms of coke per kilogram of COG injected, which significantly reduces operating costs and the CO2 footprint at the same time. COG injection technology uses special lances to ensure safe and reliable injection of the highly toxic and explosive coke oven gas via the tuyeres into the blast furnace.
The scope of supply for this project includes the plant engineering as well as the delivery of the entire process equipment including compressor station, electrics and automation.

In order to supply the gas to the blast furnace in an optimized manner, the selection of a suitable compressor technology and the control of the temperature range are decisive success factors to ensure smooth operation of the system. Paul Wurth’s advanced system automation supports the smooth and safe operation of the plant by implementing systems for fully automatic flushing, flow monitoring and lance cooling for each injection line.
The project is scheduled to be completed within 25 months so that the new plant can go into operation in the first quarter of 2026.
Tata Steel and SMS Group can look back on many years of cooperation, during which SMS Group has positioned itself both as a full-range supplier of blast furnace technology and as a pioneer of customized solutions for reducing CO2 emissions.
India has set itself the goal of reducing its CO2 emissions to net zero by 2070. The implementation of this innovative technology is not only a milestone for India, but also a significant step towards achieving this goal. SMS Group’s leading role in this area is also underlined by the nomination of the COG injection system realized in Gijón, Spain, for the prestigious Steelie Award of the World Steel Association in 2022.
Subodh Pandey, Vice President Operations, Tata Steel Meramandali, NMB & Graphene, Tata Steel, said: “The introduction of this technology is not only a record-breaking success for India, but also a strategic step towards India’s goal of becoming emission-free by 2070. By laying the foundation for a greener future, the collaboration with SMS Group is not only a milestone for us but also a flagship project for the entire Indian steel industry. By using state-of-the-art technologies such as COG injection, we are not only reducing our carbon footprint but also setting new benchmarks in environmental protection while improving our operational efficiency and competitiveness in the global market.”
Rene Gaiola, Head of Injection Technologies at SMS Group: “We are fully committed to #turningmetalsgreen and believe that the successful implementation of this project is just the beginning of a long-term partnership with Tata Steel to implement further steps to decarbonize the Tata steel plant in Meramandali.”
