D7.1 – Report on the Technical Evaluation of the Developed Technologies, Processes and Equipment

This report presents the technical evaluation of the hydrogen combustion technologies, industrial processes, and equipment developed and tested throughout the HyInHeat project. It serves as a summary of the activities conducted within Work Package 7. The transition from conventional fossil fuels to hydrogen in industrial heating applications requires a thorough assessment of process performance, emissions, product quality, safety, and operational reliability. Evaluating these aspects is essential to demonstrate the technical feasibility of hydrogen as a replacement fuel for energy-intensive industries such as steel and aluminium production.

The evaluation covers a range of industrial demonstrators, including reheating furnaces, melting furnaces, ladle preheating systems, radiant tube technologies, and heat treatment applications. The results compare hydrogen combustion with conventional fuels and assess the impact on key performance indicators such as energy consumption, emissions, process efficiency, and product quality. The findings provide valuable input for the industrial deployment of hydrogen technologies and support the development of future hydrogen-ready heating systems.

Work Package 7 is a collaborative effort involving the following partners: AGA, EHS, CTEC, TME, DAN, SPE, AMI, BEF, SWER and AMS.
