TWINGHY, the five-year EU project aimed at reducing CO2 emissions in the steel industry, has reached its halfway point.

TWINGHY aims to introduce hydrogen as a fuel to replace natural gas in steel reheating furnaces. The project was proudly represented at the 20th International IFRF Conference in June by IFRF Vice President Sébastien Caillat of Fives Stein and colleagues from partner organisations, namely the Department of Industrial Furnaces and Heat Engineering at RWTH Aachen University and Celsa.

Latest developments reported to the General Assembly in early October include the installation of eight hydrogen-compatible AdvanTek burners in a reheating furnace at Celsa in Barcelona, Spain. Designed by Fives, the burners have undergone the initial testing phase. Final tests with hydrogen are scheduled for early 2026.

The next steps are to install two oxy-combustion systems in the soaking zone, set up the hydrogen skid and piping, and conduct new burner tests to assess performance and product quality. Digital twin technology will be further developed to help control furnace behaviour and improve operations.
