Badische Stahlwerke tests flexible use of hydrogen in EAFs

Badische Stahlwerke (BSW) has launched a research project on the development of a new burner technology in electric arc furnace mills, Kallanish hears from the German rebar maker.

The burners used today for heating of the ladles are not enabled for operation with hydrogen, BSW explains. Those developed and tested in the project will be working on hydrogen, or, alternatively, ammonia. The system will be able to flexibly mix hydrogen and ammonia with natural gas, which will be used as a bridge agent until sufficient hydrogen or ammonia are available.

Project partners are associated engineering company Badische Stahl Engineering GmbH (BSE) and university RWTH Aachen. The project will run over three years, and will be subsidised by Germany’s economy and climate protection ministry to the tune of €2.3 million ($2.5m).

“The project goes beyond the reduction of CO2 emissions in ladle heating. It might be extended over the entire electric arc mill, including the meltshop,” says Sebastian Baumgartner, managing director of BSE. In that case, the technology could be marketed internationally through BSE, he notes.

BSW has set itself the target of becoming climate-neutral by 2045.
