On December 10, 2024, the U.S. Department of Energy's Advanced Materials and Manufacturing Technologies Office (AMMTO) announced 14 selections under its Critical Materials Accelerator program. The initiative aims to validate small-scale technologies and processes to hasten commercial readiness and adoption, particularly focusing on addressing critical materials challenges in high-impact energy supply chains. The selected projects target areas such as hydrogen fuel cells, semiconductors, wind turbines, batteries, and motor design. The projects include Celadyne Technologies' endeavor to develop low-platinum and iridium membranes for hydrogen devices, Free Form Fibers' innovative approach to manufacturing high-purity silicon carbide for semiconductor chip technology, Virginia Tech's GAME technology for boosting critical mineral production, and Texas A&M University's method for recovering rare earth elements from e-waste. These initiatives aim to reduce critical material demand, enhance manufacturing sustainability, and optimize processes through life cycle assessment and techno-economic analysis. The projects seek to advance technology readiness levels, promote industry partnerships, and contribute to the domestic production of essential materials. By fostering innovation and collaboration, the program propels advancements in material technologies critical for a sustainable and secure energy future.
