1. A process for producing borohydride compounds, comprising:
- (A) reacting methane with a Y-containing species of formula Y2O to obtain Y, carbon monoxide and H2;
(B) reacting the Y with H2 to obtain YH;
(C) reacting a boron-containing species of the formula BX3 with the YH to obtain YHBX3;
(D) separately reacting BX3 with H2 to obtain B2H6 and HX; and
(E) reacting the YHBX3 with B2H6 to obtain YBH4 and BX3, wherein Y is selected from the group consisting of the alkali metals, pseudo-alkali metals, an ammonium ion, and quaternary amines of formula NR4+, wherein R is independently selected from H and straight or branched C1 to C4 alkyl groups; and
wherein X is selected from the group consisting of halides, alcohols, alkoxides, chalcogens, and chalcogenides.
