Researchers from EPFL in Switzerland and Kyoto University in Japan have developed a groundbreaking hydride-based deep eutectic solvent (DES) for storing hydrogen. This clear, stable liquid material can hold an impressive 6.9% hydrogen by weight and remains in a non-crystalline state at room temperature. When gently heated to 60°C, it releases hydrogen cleanly. Surpassing the U.S. Department of Energy's 2025 targets for hydrogen storage, this innovation eliminates the need for bulky high-pressure cylinders and ultra-cold cryogenic systems. The potential commercialization of this technology could revolutionize hydrogen infrastructure, making storage and transportation simpler and safer. Moreover, this breakthrough opens doors for enhanced integration of hydrogen in fuel cell vehicles, industrial processes, and future clean energy grids. The impact of this discovery could lead to a more sustainable and efficient energy future, marking a significant step towards widespread adoption of green hydrogen.
