Magnesium is considered as a potential material for the separation of hydrogen from different gas streams (CH 4 /H 2 , syngas, natural gas, etc.). Herein, an elemental mixture of Mg and Ni (5 wt%) is used for selective absorption of hydrogen from a CH 4 /H 2 (90:10) mixture at 350 °C. The performed studies (X‐ray diffraction, thermogravimetric analysis, differential scanning calorimetry, and gas chromatography) show that analyzed material absorbs 4.5 wt% of hydrogen from CH 4 /H 2 gas mixture and can be successfully applied for H 2 separation. The proposed material may also be a promising system to capture hydrogen transported through natural gas networks.
