A team of researchers from the Institute of Chemical Technology (ITQ) and the Institute of Information and Communications Technologies (ITACA) at Universitat Politècnica de València (UPV) has made significant advancements in the field of hydrogen production. By focusing on improving the process of obtaining hydrogen from water using microwave radiation, the team has enabled the extraction of green hydrogen from renewable electrical energy sources, thereby reducing CO2 emissions associated with hydrogen production. The research primarily targets enhancing green hydrogen production through redox cycles, where materials efficiently separate oxygen from water by responding to microwave radiation, leading to electrified processes at lower temperatures. The team's work highlights the importance of material design to tailor the production of oxygen and hydrogen, optimizing the energized state of the materials for specific applications. By introducing different dopants into the matrix material, such as cerium oxide, the researchers have conducted a detailed study to adjust the interaction with microwave radiation and enhance hydrogen production capacity. The study, which resulted in a publication in the Advanced Energy Materials journal, confirms the strength and stability of the materials designed for hydrogen enhancement. The project, supported by funding from the Ministry of Science, Innovation and Universities through European NextGenerationEU funds and Ramón y Cajal contracts, signifies a significant step towards sustainable hydrogen production. The innovative research conducted at UPV in collaboration with CSIC showcases the potential of material-based solutions in advancing green hydrogen technology and contributes to the global efforts for a more sustainable energy future.
