Técnicas Reunidas participates in project to promote the valorization of waste from the iron, steel sector with renewable H2

The HYMET project aims to study new technologies applicable in the steel industry for the revalorization of by-products of the process itself and decarbonization using renewable raw materials, such as H2.

Led by CELSA Group, a leading company in Europe in the manufacture of circular steel and one of the largest recyclers in Europe, the HYMET project has a total estimated budget of €5.8 MM and has been supported by the Center for the Development of Industrial Technology through the MISSIONS call and has a grant of €3.9 MM.

HYMET proposes the study and technological maturation of innovative solutions in three future vectors for decarbonization and industrial circularity such as: the valorization of industrial waste (iron oxides scale produced in rolling mills) through an innovative reduction reactor using renewable reducing agents; the generation of green H2 through high efficiency electrolysis technologies (AEM and SOEC) and, finally, the study of CO2 capture and its re-integration through Co-SOEC electrolysis technologies for the generation of synthesis gas.

Objectives of TÉCNICAS REUNIDAS

Técnicas Reunidas is leading the research, design and experimental validation of the technological solution for the reprocessing of the by-product with gases of renewable origin (green H2 or synthesis gas). This consists of a scale reduction reactor with a processing capacity of 500 tpy continuously to obtain high quality metallic iron, with the aim of reusing it as raw material in the steel production process.

To produce these renewable gases and their incorporation into the proposed technological solution, Técnicas Reunidas is participating in the study, design and manufacture of the balance of plant for the high efficiency (>60%) electrolysis system based on high temperature SOEC technology. It will integrate the stack designed and manufactured by AMES and will be validated in a 5 kW (35 Nm3/d) electrolysis system and a 3 kW (20 Nm3/d) co-electrolysis system.
