Revolutionary Hydrogen Storage Method Unveiled for a Decarbonized Future

Scientists at the RIKEN Center for Emergent Matter Science in Japan have discovered a compound called ethylammonium lead iodide (EAPbI3) that can safely and efficiently store and release ammonia, a potential carbon-free hydrogen carrier. This finding offers a promising solution for the safe storage and transportation of hydrogen, contributing to the transition towards a decarbonized society. The compound undergoes a chemical reaction with ammonia at room temperature, transforming its structure and storing the ammonia within. The stored ammonia can be easily retrieved by gentle heating, and the perovskite can be reused for continual storage and extraction cycles.
