Research has been done in a search for hydrogen-rich glasses suitable for forming solid solutions of Cr(V) complexes, with emphasis on glasses based on amines and ammonia. The prospect for hydrogen fractions much in excess of 15 wt % seemed rather dim, but this document reports the existence of two large families of such glasses obtainable with either borane-amine complexes or ammonium borohydride as vitrifying additives. The glasses have hydrogen contents ranging up to at least 21 wt %. Moreover, at least some members of these families yield sizeable dynamic nuclear polarizations when doped with sodium bis(2-ethyl-2-hydroxybutyrato(2-))oxochromate(V) monohydrate, (EHBA-Cr(V))
