Técnicas Reunidas S.A., based in Madrid, Spain, is spearheading the H2togreenceramics project aimed at decarbonizing the ceramic cluster in the Valencian Community through green hydrogen innovation. The project involves key partners such as the Technical Institute of Ceramics (ITC) and AIJU, along with Proying XXI Ingeniería and an end-user company focused on frit production. The initiative has received partial funding from the Department of Innovation, Industry, Commerce, and Tourism of the Valencian Community to support strategic industrial projects. The first phase of the project involves integrating a 50-kW alkaline electrolyzer into the ITC Low Carbon Plant, where experimental tests will be conducted to study the continuous operation of the electrolyzer-burner-combustion chamber system. The goal is to assess the technical feasibility of using hydrogen as a fuel for firing ceramic tiles, potentially replacing natural gas. Following the successful completion of the initial phase, the project will progress to the next stage, where a more advanced 500 kW electrolyzer will be installed in a ceramic frit manufacturing company. This phase will focus on validating the technology in an industrial environment by integrating hydrogen and oxygen into the company's natural gas distribution network. The aim is to create gas mixtures with hydrogen content of up to 20% by volume, making necessary adjustments for safe operation in existing oxy-combustion furnaces. Subsequent experimental tests will be conducted to assess the melting of frits and the overall viability of hydrogen integration in industrial processes.
