At the Future Steel Forum 2025 in Barcelona, Spain, Anna Domènech, Head of Corporate Innovation at the Celsa Group, gave a presentation entitled ‘The Digital Edge of Green Steel’. She highlighted how digitalisation is reshaping the steel industry in order to address the challenges of sustainability, competitiveness and adaptability. 

She focused her talk on the integration of data, simulation and AI across the steel value chain, from scrap processing to final transformation, emphasising the need for flexible, knowledge-driven processes. She outlined how digital enablers such as forecasting, traceability, and optimisation are essential to achieving decarbonisation and circular economy goals. 

Among the initiatives mentioned, the TWINGHY project was emphasised as a key example of how digital tools can accelerate the transition to fossil-free steelmaking. TWINGHY is developing hybrid burners that can undergo direct hydrogen-oxygen combustion in reheating furnaces. These burners are supported by a digital twin that enables real-time monitoring and control of the process. 

This innovative approach aims to reduce CO₂ and NOx emissions while ensuring compatibility with existing infrastructure and preserving operational efficiency and product quality. TWINGHY’s contribution to the sector was presented as a benchmark for how digitalisation and sustainability can be combined. 

The speaker also stressed the importance of a human-centric approach to digital transformation. She called for greater investment in upskilling, knowledge management, and user engagement, recognizing that technology alone is not enough—people must be empowered to drive change. 

The presentation concluded with a clear message: digitalisation unlocks the full potential of green steel. Projects like TWINGHY exemplify how innovation can be applied not only to processes, but also to business models and workforce development, paving the way for a more resilient and sustainable steel industry.
