Stéphane Abanades and Isabel Villafan-Vidales CO2 valorisation based on Fe3O4/FeO thermochemical redox reactions using concentrated solar energy International Journal of Energy Research 37
A solar thermochemical process to recycle and upgrade the CO2 emissions has been experimentally demonstrated. CO2 is dissociated by two-step solar chemical looping with iron oxides for the production of synthetic fuels. Thermogravimetric analysis showed the high reactivity of solar-produced FeO with CO2 to generate CO that can be further processed to syngas and liquid fuels by catalytic processes. The process thus converts low-grade feedstock to high-value solar fuels.
