A research team at TU Bergakademie Freiberg in Germany is revolutionizing hydrogen production by investigating the recycling of rare earth metals from used electrolysis cells. These cells, critical for the future of energy, contain metals like scandium, lanthanum, and cerium, making them valuable for sustainable energy solutions. The team's focus on hydrometallurgical recycling methods aims to recover these metals from electrodes and reuse them, reducing the need for primary raw materials. The innovative approach involves separating electrodes from solid electrolytes and using acids to leach rare-earth metals from the electrodes. The method is environmentally friendly and emphasizes sustainability in the energy industry. The project, GrInHy3.0, in collaboration with industry partners, aims to develop a novel technology for hydrogen production using recycled metals, minimizing the environmental impact of future waste streams. The technology will be tested at operational facilities to validate its efficiency in producing hydrogen. Supported by the German Federal Ministry for Economic Affairs and Energy, this initiative showcases a promising step towards a more sustainable and eco-friendly energy future.
