Storing hydrogen is costly. Researchers in Germany proposed storing hydrogen in palladium nanoparticles. To ensure that the tiny particles are sufficiently sturdy, they are stabilized by a core made of the rare precious metal iridium and attached to a graphene support. They are attached at intervals of two and a half nanometres resulting in a regular, periodic structure. When the palladium particles come into contact with hydrogen, hydrogen sticks to the nanoparticles’ surfaces, with hardly any of it penetrating inside. A small amount of heat is added to release hydrogen from the surface of the particles. They want to find out what storage densities can be achieved using this new method. Before proceeding to practical applications some challenges be overcome include finding other forms of carbon structures which may be more suitable carriers than graphene, or consider using carbon sponges, containing tiny pores…read more.
