Abstract:

This study aims to evaluate the energy- and CO2 performance of different technologies for heating furnaces in the iron and steel industry. The evaluation was carried out using the TIMES Sweden industry model, updated with improved techno-economic data for heating furnaces. The performance of the technologies was evaluated by applying a set of scenarios that simulates the potential circumstances in terms of resource availability and energy commodity costs under which the industry needs to be decarbonised. The results show that heating furnaces can reach net-zero emissions under very varying circumstances. Three types of energy sources provide the best options in all scenarios and are thus critical for lowering emissions in the case of Sweden. These are methane fuels (i.e. natural gas and bio-SNG), hydrogen (biomass-based and from electrolysis) and electricity. Thus, the challenge moving forward is to achieve a quick technology development that enables multiple options for fuel and electricity use.
