Hydrogen storage is vital for using hydrogen as clean energy. Scientists are working on storing hydrogen safely and efficiently. They study solid materials like boron or aluminum hydrides because they can hold a lot of hydrogen. These materials could help solve the problem of storing hydrogen for cars or other uses. The researchers aim to make materials that can store a lot of hydrogen, work at mild temperatures, and release the hydrogen safely. Excitingly, they have found some materials that can store over 5% of hydrogen by weight, which is a lot! They hope to develop even better materials to store hydrogen effectively for a long time.
