Overall project concept

GreenHeatEAF will adapt, develop and demonstrate technologies for integrating non-C gases and renewable C-materials and for obtaining a wide control range of the whole heat capacities in EAF processes considering EAF role in both scrap- and iron-based route.

It will consider 3 use cases:

• Integration of non-C gases flows;
• Fossil C-sources replacement with biomass/biochar
• Modular and alternative heat recovery 

It will include parallel and complementary application of demonstration and pilot tests, digital simulation and monitoring, and control strategies.

Demands and overall project objectives

The EAF steelmaking process needs to adapt to new challenges:

• change from fossil C and energy sources to bio-based C and green H2;
• use of different iron carriers from first grade scrap to more DRI/HBI with various C-content and low-grade scrap;
• decrease of heat/energy losses with advanced/modular recovery technologies and advanced control systems;
• material valorization considering by-products changes.

Therefore, the main project objective is to to demonstrate the integration of non-fossil fuels and renewable C-sources in EAF processes to decrease CO2 emissions and dependence from fossil energy and C-sources markets by also focusing on improvement of heat recovery solutions.

Technical objectives

Transferability of the GreenHeatEAF solutions are ensured by different business cases belonging to the several industrial partners. The technical objectives of the project aims to:
