EAF steelmaking is the key technology for decarbonised steelmaking, either in scrap-based plant by modification of existing processes for further decarbonisation, or as new EAF installations in decarbonised integrated steel works to (partly) replace the classical BF-BOF production. At same time the EAF is the most important example for modular and hybrid heating, already now combining electric arc heating with burner technologies. Consequently, it was selected as main focus of GreenHeatEAF for the Call „Modular and hybrid heating technologies in steel production“. GreenHeatEAF develops and demonstrates the most important decarbonisation approaches at EAFs including the use of hydrogen to replace natural gas combustion in existing or re-vamped burners or innovative technologies like CoJet. Furthermore, decarbonisation of EAF steelmaking by solid materials like DRI/HBI and renewable carbon sources like biochar is tackled. Technologies to re-optimise the heating management with maximum heat recovery of off-gas and slag employing new sensor and soft-sensor concepts as well as extended digital twins are developed: as result the extended CFD and flowsheeting models, and monitoring and control tools will prognose the influences of the different decarbonisation measures on EAF and process chain to support upcoming decarbonisation investments and to enable the control of decarbonised hybrid heating with maximum energy efficiency. GreenHeatEAF combines trials in demonstration scale, e.g. in combustion- and EAF-demo plants, with validations in industrial scale and digital optimisations with high synergy. Thus, it completely follows the Horizon Twin Transition and Clean Steel Partnership objectives and the target to progress decarbonisation technologies from TRL 5 to 7. This synergic concept of GreenHeatEAF supports implementation and digitisation to speed up the transition of the European steel industry to highly competitive energy-efficient decarbonised steel productio

ELECTRA demonstrates that electric heating can substitute fossil fuels in the cement, lime, and pulp industries. ELECTRA develops and validates in real life emission-free, electrically heated cement and lime production process in MW scale capable of reaching temperature up to 2000°C. By using low-emission electricity instead of combustion for decomposing calcium carbonate, and by capturing the carbon dioxide produced in the production process, it is possible to run a cement plant with close to zero carbon dioxide emissions providing even negative-emission cement and lime products for the society. Successful implementation of ELECTRA will eliminate fuel-related CO2-emissions from the industries targeted by 30-50% of total process emissions, depending on the industry and mode of operation. Scalability and replicability is showcased by the platform-based solutions offering modularity, and the possibility is there to run in various hybrid modes in a transition period, lowering initial CAPEX. They allow for both new electric installations and revamping of old ones. Platform-based modular automation practices can potentially accelerate electrification by up to 5 years. Different applications also require different properties for lime and therefore variations of electrically heated processes are developed to support and complement MW scale demonstration. Replacing combustion processes with electricity-based solutions and significantly increasing emission-free electricity production is an effective means of mitigating climate change. As one of the ingredients for concrete, cement is the world's most used building material and globally the largest CO2 emitter of all industrial sectors. The results of ELECTRA contribute directly to the ambitious goal of eliminating direct CO2 emissions from the lime, paper and cement industries. The developed fully electrified solutions for calcination and clinkering will offer the cheapest option for decarbonation for these industries.
