Climate changes, carbon depletion, greenhouse emissions and worldwide raising energy demand are becoming increasingly important problems. This opens the door to innovative and green pathways for electric/thermal power and fuels production. In the present study, a polygeneration plant integrated with a chemical looping fed by concentrated solar power for the production of electricity, heat, dimethyl-ether, methanol and syngas is analysed and discussed. The prime mover of the plant is the two-step chemical looping, operating at 1.2 bar and 900°C. The redox pair CeO2/Ce2O3 coupled with biomethane partial oxidation is chosen for its manifested advantages compared to other materials. The reduction reaction is endothermic, heat is provided by concentrated solar energy.
