Borohydrides such as NaBH4 in an aqueous solution of caustic soda have the highest gravimetric and volumetric storage densities compared with all other hydrogen storage options, including liquid hydrocarbons (see Section 2.1). The reaction with water is exothermic ... 

One of the first MOFs investigated for H storage was the cubic carbox-ylate-based framework MOF-5 or IRMOF-1, IRMOF-6, and IRMOF-8 (Fig. 3.5) [28]. With complete activation, MOF-5 can adsorbs 7.1 wt% H at 77 K and 40 bar and 10.0 wt% at 100 bar. The latter value is corresponding to a record volumetric storage density of 66 g L" which is near the density of liquid Hj at 20.4 K and 1 bar [29]. This MOF material is the best cryogenic storage material currently known. In addition, it was demonstrated that Hj can...
