Assessing the role of negative emission technologies in the low carbon transition of the iron and steel sector
Résumé
The iron and steel industry (ISI) is responsible for 8% of global CO 2 emissions. Then it is urgently needed to find more sustainable pathways if the ISI aims to contribute to global environmental objectives. Many innovative clean alternative technologies, e.g. hydrogen-based steel production, are proposed to reduce the emissions in this sector, however, they are not available yet, and they do not completely reduce emissions; mainly due to process emissions and residual use of fossil fuels. Then replacing fossil fuels with biomass in combination with carbon capture and storage or utilization (CCS/CCU) could be a prominent solution to reduce the environmental impact as it is possible to produce negative emissions. Then, negative emission technologies (NETs) might help to compensate for the residual emissions of the sector. In this sense, through a bottom-up energy prospective modeling, this paper explores how NETs could contribute to the decarbonization of the ISI
