| Abstract: | The addition of nickel as catalyst and particle size reduction through milling process is considered as the best approach for MgH2 properties to be thermodynamically and kinetically more favorable. The recent development in MgH2 is done by adding Ni (14–16 wt%) and particle size reduction through simple mechanical milling at a large sample of 100 g. The research sequences are easy to adopt for the implementation and sustainable research of MgH2. Starting from the moisture test to the milling process, continue with particle size distribution (PSD) for the milled sample and final moisture test after PSD. Some critical finding from our research includes high capacity storage of Mg84:Ni16 above 5 wt% H2 within 20 min at 573 K, the effect of moisture content on system performance and the different effect of carbon (C) in the system at specific temperature and pressure that may have. |
