rp.pl Lublin-Wrotków power plant, the largest producer of carbon dioxide in the Lublin, Poland, and the University of Maria Curie-Sklodowska will sign a letter of intent on cooperation for the production of methanol from carbon dioxide using a technique developed by Prof. Dobieslaw Nazimek at the University.

Nazimek says his “artificial photosynthesis” process is based on the photocatalytic conversion of water and carbon dioxide under deep ultraviolet light. Synthesis of 1 kmole (32 kg) of CH3OH from CO2 and H2O requires 586MJ of energy, according to Nazimek’s calculations. (Methanol has a HHV of 22.7 MJ/kg, or 726 MJ/kmole).
An experimental photoreactor unit (0.5m, Ø: 4 cm) supports a flow of CO2 of 370 dm3/h (13 cubic feet), and produces 544 g methanol per hour (15% of the product solution).
Prof. Nazmiek said that “In Poland it costs around zł0.4 to acquire a liter of methanol. Our method allows to get the same effect for zł0.09-0.11.”
