Técnicas Reunidas is at the forefront of the decarbonization efforts in the ceramic industry through their leadership in the H2togreenceramics project. This project, based in the Valencian Community, Spain, focuses on the research and application of green hydrogen to reduce the carbon footprint of ceramic production. With the participation of technological centers, companies, and end-users, the project aims to develop alkaline electrolyzers for efficient hydrogen generation to be used in industrial processes. Supported by funding from the Valencian Community, the project has a significant budget and potential to enhance energy autonomy within the ceramic cluster. In the initial phase, a 50 kW alkaline electrolyzer will be integrated into a pilot plant for experimental trials, with the objective of studying the feasibility of using hydrogen in the ceramic firing process. Subsequent phases involve scaling up to a 500 kW electrolyzer to validate the technology in an industrial setting, potentially replacing natural gas with hydrogen. By integrating hydrogen and oxygen into the company's gas distribution network, the project aims to achieve up to 20% hydrogen volume in mixtures to be tested in existing combustion furnaces. The ultimate goal is to assess the technical feasibility and sustainability of transitioning to hydrogen as a fuel source in ceramic production. The positive sentiment around this initiative indicates a promising step towards a more sustainable and environmentally friendly ceramic industry.
