“…Compared with high cost cryogenic liquid storage and dangerous high compression gas tanks, hydrogen stored in solid-state materials shows easy manipulability temperature, low working pressure (Khafidz et al, 2016 ; Rusman and Dahari, 2016 ; Razavi et al, 2019 ). In the past decades, oceans of materials for hydrogen storage have been investigated, including physical adsorbents (carbon and MOF), complex hydrides (LiBH 4 , LiNH 4 , NaAlH 4 ), alloys hydrides (Mg 2 NiH 4 , TiFeH 2 , NaMgH 3 ), and metal hydrides (MgH 2 ) (Shao et al, 2015 ; Zhai et al, 2016 ; Xiao et al, 2017 ; Chen et al, 2019 ; Goto et al, 2019 ; He et al, 2019 , 2020 ; Liu H. et al, 2019 , 2020 ; Song et al, 2019 ; Jansa et al, 2020 ; Yao et al, 2020 ).…”
