‘Nano-Chocolates’ that Store Hydrogen

The palladium nanoparticles (green) are stabilised by a core of iridium (red). Hydrogen can accumulate on their surface like a kind of chocolate glaze – and can be released again by heating. Credit: DESY, Andreas Stierle

Innovative ideas for the energy carrier of the future. An innovative approach could turn nanoparticles into simple reservoirs for storing hydrogen. The highly volatile gas is considered a promising energy carrier for the future, which could provide climate-friendly fuels for airplanes, ships and lorries, for example, as well as allowing climate-friendly steel and cement production — depending on how the hydrogen gas is generated...
