Researchers from the Institute of Chemical Technology (ITQ-CSIC-UPV) and the Institute of Information and Communication Technologies (ITACA) at UPV in Spain have collaborated to develop a groundbreaking process for obtaining hydrogen from water using microwave radiation. The research aims to produce green hydrogen from renewable electrical energy sources, reducing CO2 emissions associated with traditional hydrogen production methods. Published in the journal Advanced Energy Materials, the study focuses on enhancing green hydrogen production through redox cycles that separate oxygen from water in a stable manner. By leveraging microwaves, the process's temperature requirement is significantly reduced from 1,300°C to 400°C, simplifying the production process and maximizing energy efficiency. The key innovation lies in the meticulous study of material properties to optimize performance and adapt production of oxygen and hydrogen according to specific applications. The design of materials with redox properties that respond to microwave radiation enables efficient electrification of the process. The study also highlights the resistance and stability of the materials used in the hydrogen production process. The project, funded by the Ministry of Science, Innovation, and Universities of Spain and the Regional Government of Valencia, showcases the potential of microwave technology in revolutionizing green hydrogen production for a more sustainable future.
