The steel industry is a fascinating area of research because efficiency measures have a big impact. For example, after the implementa-tion of OxySteel, we expect annual energy savings of 12 GWh. This equates to approx. 10 % of the annual natural gas consumption of the city of Leoben. Considering a subsequent technology rollout, the savings are a multiple thereof.

OxySteel encompasses the increase of energy efficiency by the use of novel technologies and the evaluation of DSM potentials in a steel mill. The first goal is tackled by the development and implementation of a new process design using oxy-fuel combustion and CCU. The second objective is to identify flexibilities for the increased use of renewable energy sources and possible grid services.


  • Identification of flexibilities and energy efficiency in process heat productionby the use of oxyfuel combustion.
  • Replacement of gas burners by oxy-fuel burners.
  • Reduction of the required electrical storages and support of the stability of the electrical power grid.
  • OxySteel demonstrator project in the Breitenfeld Edelstahl AG steel mill.
