NOVELTY - Continuous process (p1) for reducing greenhouse gas release associated with production of alcohol comprises: contacting combined gas substrate with aqueous menstruum to bioconvert the substrate to alcohol and provide alcohol-containing menstruum and depleted gas phase; (b) continuously withdrawing depleted gas phase from menstruum; and (c) continuously withdrawing aqueous menstruum for recovery of alcohol which contains carbon from a renewable resource, where withdrawal maintains alcohol below a concentration that unduly adversely affects the microorganisms.    USE - The process is useful as continuous process for reducing greenhouse gas release associated with the production of alcohol from natural gas and for making alcohol.    ADVANTAGE - The process: utilizes non-renewable carbon oxide sources while still lowering the carbon footprint to produce alcohols preferably ethanol; provides renewable portion of the alcohol having reduction in greenhouse gases by greater than or equal to 50% when compared to gasoline in a cost effective manner, thus additional carbon dioxide from carbohydrate fermentation processes is readily available for balancing the overall electron/carbon value, and higher alcohols with a renewable carbon component, high conversion and efficient processing; balances electron to carbon atom ratio without the need for any generation of hydrogen via a water gas shift reaction or other means; and avoids any further unit operation that is provision of a water gas shift step to change the hydrogen input to the process and eliminates need for such a unit operation, thus providing cost and operational advantage.
