At Celsa’s headquarters in Barcelona, all the entities involved launched the Twinghy project to further advance the decarbonisation of the steel sector: the Digital TWINs for Green HYdrogen transition in the steel industry project. The main objective of this project is to study the substitution of natural gas by hydrogen in the reheating process, where natural gas is the main source of CO2 emissions. 

The demonstration of an advanced heat transfer process in the reheating furnaces of the steel sector, through the use of hybrid burners to increase the introduction of hydrogen for direct combustion with oxygen, will be tested through a digital twin of the furnace based on the use of high-fidelity simulations, sensor data and Machine Learning (ML) using High Performance Computing (HPC) to monitor and control the operational process. 

The Twinghy project will last 54 months, from 2023 to 2027. It is funded by the European Union’s RFCS Big Ticket programme under Grant Agreement No. 101099158.  

Nine partners from France, Germany, Sweden, Spain and Finland are meeting in Barcelona for a visit to the Celsa plant to understand the industrial process of steel production.
