Danieli, Tenova’s ENERGIRON ZR Technology Sets Record in Energy Efficiency at Suez Steel’s DRP
04/16/2026 - Danieli announced its jointly developed technology with Tenova, the ENERGIRON Zero-Reformer (ZR), helped set a record in energy efficiency for gas-based reduction at Suez Steel’s direct reduction plant (DRP).
The companies said the technology operates with high metallization rates and ensures direct hot feeding to the meltshop. Suez Steel was able to reach natural gas consumption below 2.2 Gcal per metric ton consistently for several months of continuous operations.
“This result has been the achievement of all the team steadily focused in seeking the best performance through relentless commitment on continuous improvement and technology development in constant partnership with our technology partners of ENERGIRON,” said Zulfikar Uddin, technical manager of Suez Steel.
Suez Steel said the new captive pellet plant it recently commissioned was key to the record, allowing pellets with optimal reducibility characteristics to ensure stable and efficient DRP operations.
“We are proud of these results that show the potential of the ENERGIRON process, especially when the management and the team is devoted to production and to investigate the best synergies to push the process closer to its theoretical limit,” said Marco Lapasin, vice president of Danieli Centro Metallics.
