The Gwangju Institute of Science and Technology (GIST) has found an optimal hydrogen-natural gas blend that is capable of trapping hydrogen in cage-like molecules boosting efficiency in storage.
Unlike hydrocarbons, pure hydrogen must be stored at an extremely high pressure (>100 atmospheres) or low temperature (−20°C) naturally representing a huge economic barrier for hydrogen storage.
Gwangju theorised about trapping hydrogen inside ice-like crystals that could help make storage and transportation less demanding for the zero-emission fuel.
These molecular cages already exist in nature and are called ‘clathrate hydrates’ which are solid water-based compounds with cavities that can accommodate various molecules.
