CSN – Companhia Siderúrgica Nacional reduces fossil fuel consumption with innovative Technology UTIS

CSN – Companhia Siderúrgica Nacional is spearheading the transformation of sustainable steelmaking by implementing, for the first time globally, the UC3 technology developed by the Portuguese company UTIS in the blast furnace 2 at the Presidente Vargas Plant (UPV) in Volta Redonda, Brazil.

How does the technology work?
The UC3 technology uses renewable hydrogen to optimize combustion in the blast furnace regenerators. This leads to higher blast temperatures, reduced fossil fuel consumption (such as coke and natural gas), and lower CO2 emissions. According to Fabiam Franklin, CSN’s metallurgy director, the regenerator temperatures increased by 7%, boosting thermal efficiency and productivity.

Environmental and Economic Impacts

  • Emission reductions: Aligned with CSN’s goals to reduce its carbon footprint by 2030, the technology is already delivering significant results.
  • Resource savings: The decrease in coke and natural gas consumption equates to preventing the emission of hundreds of tons of CO2 annually.
  • Sustainability in action: Easy to install, the system has already proven successful at CSN Cimentos, reducing CO2 emissions by 5% per ton of clinker produced.

Looking Ahead
This groundbreaking application underscores CSN’s commitment to leading innovation in the steel industry. Moreover, UTIS aims to expand the UC3 technology to other sectors, such as cement and biomass, with new applications planned in Brazil by 2025.

“We are thrilled with the evolving results of our partnership with CSN, now extending into steelmaking processes. The goal is to optimize steel production while substantially reducing carbon emissions, contributing to a more sustainable future for the industry,” said Paulo Gonçalo, UTIS’s Executive Director.

This technology demonstrates that transforming industries through innovation and environmental responsibility is possible, paving the way for a more sustainable future for our planet.
