Ultra-high density hydrogen storage

A nanoporous material that holds hydrogen at twice the density of cryogenic liquid H2 could address the challenges of large-scale liquid and gas storage that have held this clean fuel back….

The team synthesized nanoporous magnesium borohydride (Mg(BH₄)₂), a framework with partially negatively-charged hydrogen atoms forming the nanopore’s inner surface, enabling the uptake of hydrogen and nitrogen.

Although both nitrogen and hydrogen can enter the pores, the researchers found that the gas uptake for hydrogen was larger by a factor of three as both occupy different adsorption sites in the pores.
