How is Methanol Produced? While today we produce methanol from natural gas, methanol can also be made from renewable sources, such as renewable natural gas, biomass and green hydrogen combined with recycled carbon dioxide. Methanex is studying the feasibility of converting our existing assets to produce lowercarbon intensity methanol. We are committed to pursuing opportunities [.]

The coaltomethanol (CTM) is an important technical route for methanol production. The process suffers from high CO2 emission and low energy efficiency due to the mismatch of H/C (hydrogentocarbon) ratio between raw coal and products. Hydrogen production from renewable energy can be introduced into the system to meet the H/C ratio.
