Hydrogen storage material's key restriction identified

https://phys.org/news/2023-01-hydrogen-storage-material-key-restriction.html

"Magnesium hydride's (MgH2) bond strength decreases as dehydrogenation process continues... Hydrogen migration and desorption easier following initial burst effect... Structural engineering tweaks that promote this desorption process key to facilitating hydrogen desorption of MgH2... establishes important guidelines for modifying MgH2-based hydrogen storage materials...  paves way for widespread commercial use"
