ONLiNE UPSC · Accepted Answer

Statement 1 is correct: Methanol synthesis is achieved by chemical reaction between CO2 and H2, this method being considered an important method for carbon dioxide valorization. The main advantages of this route are the reduction of greenhouse gas emissions and production of a valuable chemical, methanol.

Statement 2 is not correct: The idea of using photochemical reduction of CO2 with solar energy to produce methanol is attractive for sustainable energy and reducing greenhouse gases, the process is not yet a commercially established method for methanol production, though research and development efforts are actively pursuing its potential.
