Solar hydrogen production via a two-step water-splitting thermochemical cycle based on Zn/ZnO redox reactions

TLDR
In this article, a 2nd-law analysis performed on the closed cyclic process indicates a maximum exergy conversion efficiency of 29% (ratio of Δ G 298 K °| H 2 + 0.5 O 2 → H 2 O for the H 2 produced to the solar power input), when using a solar cavity-receiver operated at 2300 K and subjected to a solar flux concentration ratio of 5000.

Hydrogen production from water utilizing solar heat at high temperatures

T. Nakamura
- 01 Jan 1977 - 
TL;DR: In this paper, the authors investigated the feasibility of producing hydrogen and oxygen from water utilizing solar heat at high temperatures using a conceptual model and showed that the thermodynamic requirements for the direct thermal decomposer are difficult to realize from the structural viewpoint and that existing separation methods are not applicable for such a decomposition process if it is to attain sufficiently high thermal efficiencies.
