Such routes include ethanol fermentation (both crop-based and cellulosic) and bio-FT. The high concentration of CO2 means that the cost of capturing the CO2 is low, since no additional purification is required apart from dehydration.Scientists assessed corn ethanol’s greenhouse gas ( GHG) emission intensity (sometimes known as carbon intensity, or CI) during that period and found a 23% reduction in CI. According to Argonne scientists, corn ethanol production increased over the period, from 1.6 to 15 billion gallons (6.1 to 57 billion liters).

Fermentation from corn-ethanol plants is the largest single-sector CO2 source for the U.S. merchant gas markets.Jul 19, 2021 · The ethanol industry has long been at odds with some climate groups and activists over how good their fuel is for the environment. Ethanol is made from corn, which naturally pulls carbon dioxide from the air. But when ethanol is produced and burned, it releases CO2 and small amounts of two other greenhouse gases into the atmosphere. In the chemostat that was initially fed with a mixture of 50% starch and 50% glucose (20 g/L each), the reactor produced a mixture of lactic acid, ethanol, and acetate. Again, switches to full starch feed and full glucose feed caused an immediate shift towards lactic or ethanolic fermentation, respectively (Fig. 2 B).Under optimal production conditions and operating at capacity, to produce 1 kg of ethanol as a functional unit, a minimum of 1.91 kg of CO 2 and 0.26 kg of H 2 is required.
