Solar Fuels via Two-Step Thermochemical Redox Cycles

With the advent of green technologies, solar fuel has gained particular interest that helps in producing syngas which is the primary feedstock for many of the synthetic chemicals using emissions (CO2 and H2O). Thermochemical redox cycles use metal oxides as oxygen carriers that are capable of oxygen diffusion during continuous reduction and oxidation cycles. In the chapter, the focus has been derived in many aspects such as metal oxides and their evolution, reactor design and their scope of large-scale modularity, and lastly its application in fuel, chemicals and power plants. The chapter also highlights the system analysis for different chemicals, their techno-economic feasibility, and viability.
