Methanol production using fossil fuels, mainly from natural gas . and coal, is a mature technology [13]. Renewable hydrogenbased methanol as an alternative fuel is widely investigated by researchers worldwide [1,2,13,2224]. CO. 2. may come from flue gas, gasification of biomass, or ethanol plants [1,13,25]. Energy analysis of recycling CO. 2
