The transition towards low-carbon steelmaking requires a combination of technologies, operational optimisation, and new energy carriers. In most decarbonisation pathways, hydrogen plays a central role — both as a reductant and as a fuel.

In this steelTalk, Joachim von Schéele, Global Director Commercialisation at Linde, explains how energy-efficient oxyfuel combustion supports decarbonisation in steel production and how hydrogen can be integrated into combustion systems without compromising performance. The session outlines the fundamentals of combustion processes, the benefits of conventional and flameless oxyfuel technology, and its applications in electric arc furnace (EAF) burners, ladle preheating, and reheating operations.

The lecture also presents results and operational experience from full-scale permanent use of oxyfuel systems operating with 100% hydrogen, highlighting performance outcomes and practical considerations for industrial implementation.
