“…The adiabatic UT-3 cycle, the SulfurIodine (SI) and the Hybrigd-Iodine (HI) cycle receive much attention in the literature [64][65][66][67]. These cycles are based on a reaction scheme that incorporates more than three reactions leading to lower inherent efficiencies and high efforts for the product separation after each step.…”

a b s t r a c tThis paper provides a perspective on the technologies capable of converting solar energy, CO 2 and H 2 O into an easy to use fuel. The paper addresses bio-based approaches, but mainly focuses on (i) the combination of photovoltaic (PV) devices and electrocatalysis, (ii) single unit operation by photocatalytic conversion, and (iii) solar thermal conversion. Each option is described in a general manner, including a brief evaluation of the advantages and disadvantages. Also suggestions for future research endeavours are given. Based on the used literature data, for electrocatalytic and photocatalytic technologies, dramatic improvements should be made in material optimization, as well as reactor design and operation. Large efficiency gains are necessary to enable use of these technologies in practice. Solar thermal conversion is more mature, and requires specific optimization in processing, as will be discussed.

“…The ZnO/Zn as well as the Fe 3 O 4 /FeO redox pair have already been analyzed and tested in solar reactors [65,66,69,[71][72][73][74]. Both systems require the quenching of the reduction products in order to prevent re-oxidation.…”

“…It was found that the amount of hydrogen produced decreases with increase in H 2 O partial pressure. Figure 1 gives the compounded results for partial pressure of water equal to 0.1 bar between 1,500 and 5,000 K. Bilgen [4] experimentally demonstrated that between 2,273 and 2,773 K formation of about 2-3 % H 2 when mixture of steam and argon was passed in the crucible at the focus of the solar furnace.…”

This review mainly focuses on summarizing the different metal oxide systems utilized for water-splitting reaction using concentrated solar energy. Only two or three cyclic redox processes are considered. Particle size effect on redox reactions and economic aspect of hydrogen production via concentrated solar energy are also briefly discussed. Among various metal oxides system CeO 2 system is emerging as a promising candidate and researchers have demonstrated workability of this system in the solar cavity-receiver reactor for over 500 cycles. The highest solar thermal process efficiency obtained so far is about 0.4 %, which needs to be increased for real commercial applications. Among traditionally studied oxides, thin-film ferrites looks more promising and could meet US Department of energy target of $2.42/kg H 2 by 2025. The cost is mainly driven by high heliostat cost which needs to reduced significantly for economic feasibility. Overall, more work needs to be done in terms of redox material engineering, reactor technology, heliostat cost reduction and gas separation technologies before commercialization of this technology.
