A system for the storage and delivery of a sorbable fluid, comprising a storage and dispensing vessel containing a sorbent material having sorptive affinity for the sorbable fluid, and from which the fluid is desorbable by pressure-mediated and/or thermally-mediated desorption, wherein the sorbent material is functionally enhanced by a reagent which alters the binding energy of the fluid to the sorbent. In a preferred aspect, the system is arranged for storage and delivery of B.sub.2 H.sub.6, in which the sorbent material has sorptive affinity for B.sub.2 H.sub.6 and is effective when B.sub.2 H.sub.6 is contacted with the sorbent to convert B.sub.2 H.sub.6 to a sorbed .BH.sub.3 form, which is desorbable by pressure-mediated desorption and/or thermally-mediated desorption to release B.sub.2 H.sub.6 from the sorbent, and means for selectively discharging desorbed B.sub.2 H.sub.6 from the vessel
