It's a great idea to make methanol from CO2 + H2 + elec. This paper: for such a CCU effort to be economically viable, the price of MeOH should 2x, H2 costs decrease 2.5x, or CO2 have a value of around 222 €/t (carbon tax.) Internalize environmental costs. Solar input for water splitting to make H2 and PV for electricity.
