Ionic liquid (IL) based H 2 storage for H 2 generation from NH 3 BH 3 derivatives is shown. These systems promote H 2 generation at low temperature, with good reaction rates and high total H 2 yields. The effects of ILs and the H 2 yield in correlation with the basicity, the cations of the ILs, and the role of carbenes are discussed. Furthermore, mechanistic findings on the dehydrogenation are described. IL material blends are competitive with conventional H 2 storage materials with experimental efficiencies of at least 6.5 wt % H 2 .
