The prospects and opportunities in the conversion of carbon dioxide to fuels are discussed. The requisites for this objective are to (i) minimize as much as possible the consumption of hydrogen (or hydrogen sources), (ii) produce fuels that can be easily stored and transported, and (iii) use renewable energy sources. From this perspective, the preferable option is to produce liq. fuels from CO2 to store the solar energy in a transportable form. A new approach we developed was based on converting CO2 in a photoelectrocatalytic (PEC) device. CO2 can be converted to isopropanol using this approach, proofing the concept, although productivity and stability of operations should be improved. On a shorter term, the catalytic conversion of CO2 to methanol/DME and their eventual conversion to ethanol, using ex-situ produced hydrogen, is a feasible soln., but solving the issue of water formation during the reaction, for example, by coupling the catalyst with water permeoselective membranes.
