Digital TWINs for Green Hydrogen transition in steel industry

About

#TWINGHY aims to introduce hydrogen as a fuel to replace natural gas in the reheating furnaces of the steel sector.
The project will develop a Digital Twin to control the behaviour of the furnaces and optimize the operations.

Period of time
