The energy intensive industry (EII) is responsible for two-thirds of industrial carbon dioxide emissions in the EU. It has been recognised by both public and private stakeholders that a far-reaching transformation of these industries is required to comply with the overall emission reduction goals stated by the European Union for 2050. Contrasting innovations discussed in pathway and roadmap publications for the different industries, it can be concluded that there is little consensus on how deep decarbonisation of the EII will be achieved. This state of the art review consist of two parts. In the first part a review of pathway and roadmap publications and scientific literature is presented. This permits to identify key areas for emission abatement across all subsectors. Results show significant discrepancies in the literature regarding the expected emission reductions achievable. The first part is based on a scientific journal paper published by the same authors, which has been extended and revised for this publication. The second part presents a novel cost review for the key technologies that have been identified in the first part and could reduce emissions of the different industries significantly. This document is part of the ?Estudios para la preparación de la estrategia de Descarbonización de la economía española? which have been carried out by the IIT for the Spanish Ministry for the Ecological Transition (MITECO).
