1st RecHycle Press Release

RecHycle is an EU-funded project that investigates the use of green hydrogen and recycled metallurgical gases in steelmaking. These gases are hydrogen-rich and produced onsite. They will be injected into the blast furnace to replace coke and pulverised coal. This will help minimise carbon dioxide emissions and sustainably produce green steel.

The steel sector is one of the most challenging sectors to decarbonise and has recently received special attention to reducing its fuel combustion and process-related carbon emission. About 60% of steel production in the world is currently produced based on the Blast Furnace-Basic Oxygen Furnace (BF-BOF) route. One of the current leading technologies being developed is replacing coking coal with hydrogen-rich gases. When hydrogen is used instead of carbon to remove the oxygen from iron ore, the by-product is water rather than carbon monoxide and carbon dioxide. When hydrogen is produced using renewable sources or recycled on site using hydrogen-rich gases, it can be a steady source of
(renewable) energy.

RecHycle’s goal is to mix and recycle metallurgical gases produced on site with or without external (green) hydrogen sources. This is to be fed ultimately into the blast furnace and a future DRI furnace to sustainably produce green steel. The project will demonstrate a cost-efficient solution to decrease carbon emissions by initiating a new industrial symbiosis between and within the steel industry, chemical industry and renewable energy sources (e.g. wind or solar to obtain green electricity or hydrogen).

The project will contribute to the shift towards a circular economy where waste products are valorised to the maximum of their potential. Challenges to be addressed are the dynamic optimisation of gas mixtures and flows, minimising risks of hydrogen on material embrittlement, ceramic feed-inlet (Tuyeres) within the furnaces, the quality of the produced steel and the (future) material scrap streams of the DRI. RecHycle is to be executed through a consortium of 6 partners from 4 different countries including 1 industrial partner that is world-leading in the steel manufacturing industry and 5 research partners specialised in hydrogen-based studies.

“The roadmap of ArcelorMittal Belgium to reduce its CO2 emissions by 35% by 2030 compared to 2018 and to become carbon neutral by 2050 consists of three axes:

(1) Further improving material and energy efficiency;
(2) Electrification and embracing hydrogen as a reducing agent;
(3) Developing Smart Carbon concepts at the heart of the circular economy.

RecHycle allows us to take important steps in the three axes.”
Manfred Van Vlierberghe
CEO ArcelorMittal Belgium
“ArcelorMittal Global R&D plays an important role in supporting the decarbonisation strategy of the group, leveraging the expertise of a Press release diverse group of researchers to shape the steelmaking processes of the future. We will use modelling and advanced characterisation methods to assess and optimise the technical outcomes of the project.”
Rodolfo Santos Ferreira
Head of Blast Furnace R&D AMMR
“RecHycle is a major step in our strategy to develop materials and solutions for the new carbon-free era. We are very glad to have the opportunity to contribute with our knowledge and expertise, to make robust gas hubs for steel industry. It is of relevance for the local industry in Austria as well.”
Dipl-Ing. Dr. Vojislav Petrovic-Filipovic
Senior Researcher Joanneum
“Università Politecnica delle Marche is excited to contribute to this project and, in particular, to support the consortium in evaluating the environmental, social and economic aspects of the project. We are confident that this is the beginning of a fruitful collaboration and that the results can be an important step toward decarbonisation and circularity.”
Prof. Filippo Emanuele Ciarapica, PhD
Full Professor UPM
“CNRS and UB, in their joint lab LCTS, and IRT Saint Exupéry are committed to increase knowledge and expertise on Ceramic Matrix Composites. Initially developed for space and aircraft applications, these materials have here a fantastic opportunity to find applications in a new domain, with tremendous development perspectives and certainly new scientific challenges. In particular, proving that they are capable to enable new technologies helping to decarbonise the heavy industry is a very important asset for future research & development.”
