Solar energy storage as H2 and Br2 from HBr—II. Performance of an idealized system

Abstract: An analytical model of an archetypal device which stores solar energy as H2 and Br2 from the single-step decomposition of HBr is presented. The large differences between the molecular weights of the components of equilibrium HBr make it an attractive candidate for effusional separations. The high degree of dissociation of HBr at temperatures which are substantially lower than those which characterize water dissociation suggest that the problems of finding reactor and membrane materials will be much easier with HBr than with water. Furthermore, even if energy storage, rather than H2 production is the desideratum, HBr is worthy of serious consideration.
