News Update on Hydrogen Storage: March-2020

Hydrogen storage in metal–organic frameworks

New materials capable of storing hydrogen at high gravimetric and volumetric densities are required if hydrogen is to be widely employed as a clean alternative to hydrocarbon fuels in cars and other mobile applications. With exceptionally high surface areas and chemically-tunable structures, microporous metal–organic frameworks have recently emerged as some of the most promising candidate materials. [1]

Nanocrystalline magnesium for hydrogen storage

The hydrogen storage properties of MgH2 are significantly enhanced by a proper engineering of the microstructure and surface. Magnesium powders are produced in a nanocrystalline form, which gives remarkable improvement of absorption/desorption kinetics. [2]

Materials for hydrogen storage

Hydrogen storage is a materials science challenge because, for all six storage methods currently being investigated, materials with either a strong interaction with hydrogen or without any reaction are needed. [3]

Ball-Milled and Acid-Treated Mineral Activated Carbon as Hydrogen Storage Material

For several decades, carbon allotropes, including graphitic nanofibres and other nanostructures, have been studied as hydrogen storage materials. In this paper, activated mineral carbon (bituminous) was used for the hydrogen storage process. [4]
