Crednerite glass-ceramic material was investigated for the first time as a hydrogen storage candidate. The average gravimetric capacity was about 16 g H2/kg, 50 g H2/kg at 473 K and 573 K, respectively, under 20 bars pressure. XRD exhibits a reduction of copper ions to copper metal beside cristobalite and manganese oxide phases after exposing to H2 at 80 K and 573 K. The reduction of Cu+2 into Cu explain the irreversibility of hydrogen adsorption process.
