May 01, 2016 Hydrogen storage is an important aspect in enabling the so-called ‘hydrogen economy’.1 One of the current challenges is to develop a safe and efficient reversible hydrogen storage system. Magnesium and its alloys provide great advantages in terms of light weight, low cost, and excellent storage capacity2 e.g., 7.6 wt% H/Mg or 3.6 wt% H/Mg 2 Ni though still being limited by their …

Ultrafine Grained Magnesium Alloys for Hydrogen Storage

Ultrafine Grained Magnesium Alloys for Hydrogen Storage

Oct 04, 2019 Magnesium alloys take a special place among the hydrogen storage materials, mainly due to their high gravimetric (7.6 mass %) and volumetric (110 kg m−3) hydrogen storage capacity. Unfortunately, the kinetics of hydrogenation and hydrogen release are rather slow, which limits practical use of magnesium-based materials for hydrogen and heat storage.

An efficient approach that combines short-term (minutes) high-energy dry ball milling and wet grinding to tailor the nano- and microstructure of Ni+Al composite reactive particles is reported. Varying the ball-milling conditions allows control of the volume fraction of two distinct milling-induced microstructures, that is, coarse and nanolaminated.
