Hydrogen storage based on magnesium hydrides
Hydrogen has great potential as a future clean energy source. The main stumbling block for its wide use in stationary and portable power applications is that hydrogen gas is difficult to store. Magnesium hydrides are suitable materials for use in a hydrogen economy owing to their high gravimetric capacity, low cost and abundance. Reducing their stability in magnesium nanoalloys could boost their use in practical applications. Funded by the Marie Skłodowska-Curie Actions programme, the RHINE project will tap into the potential of electron energy loss spectroscopy to unravel the metal-hydride phase transition of magnesium nanoalloys. Furthermore, it will use four-dimensional scanning transmission electron microscopy to investigate how the interface between magnesium and magnesium hydride and strain affect destabilisation.
