“A research team…has demonstrated that the metal-organic framework material MOF-74 can absorb more hydrogen than any unpressurized framework structure studied to date, and packs the molecules in more densely than they would be if frozen in a block.

By achieving technologically relevant levels of gravimetric density for stored hydrogen without either the extremely high pressures for gaseous hydrogen or extremely low temperatures for liquid hydrogen, MOF-74 could enable practical mobile hydrogen storage…MOF-74 resembles a series of tightly packed straws comprising mostly carbon atoms with columns of zinc ions running down the inside walls. A gram of the material has about the same surface area as two basketball courts….” Full Slice
