The high concentration of CO2 means that the cost of capturing the CO2 is low, since no additional purification is required apart from dehydration.A reduction in U.S. ethanol production (for example, in response to policy changes) would inadvertently pose a significant disruption to the billion-dollar carbon dioxide industry, and the U.S. food industry. Fermentation from corn-ethanol plants is the largest single-sector CO2 source for the U.S. merchant gas markets.

In recent years, there has been a growing demand for ethanol-free gas among vehicle owners. Many individuals are concerned about the effects of ethanol on their engines and are actively seeking out alternatives.Environmental emission of carbon dioxide CO 2 when combustion fuels like coal, oil, natural gas, LPG and bio energy.

Several biofuel production pathways emit an essentially pure stream of CO2 as an inherent part of their process. 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. Two major factors affecting the process/production cost are capital and operational costs. Using Aspen Plus process simulation, the parameters affecting the operating cost for bioethanol production with and without onsite CO2 up-gradation demonstrated that the price of feedstocks (130 USD/dry U.S.ton) accounted for 70% of the minimum selling price of ethanol (Huang et al., 2020a).Research led by NREL is working on using wind power to drive electrolysers that turn the ethanol’s CO2 by-product into e-fuels, explains Erik Ringle at NREL.

Even at 60 tons per acre per year (as Cellana has generated at its 6-acre facility), that's up to 2300 acres of algae production from a single site - almost 4 square miles.Electrocatalytic reduction of CO 2 to useful fuels and chemical feedstocks is a promising strategy for carbon utilization and greenhouse gas mitigation. Among the CO 2-reduction products including CO, formate, methanol, methane, acetate, ethanol, etc., liquid multicarbon products such as ethanol and acetate are desirable because of their high energy densities and economic values (1, 2).

Moreover, the ethanol production from the hydrogenation of CO 2 is thermodynamically not favorable because of the generation of CH 4 or CO, which reduces the ethanol selectivity [43]. At present, it is a big task to get high selectivity of ethanol by utilizing catalysts at significantly high CO 2 conversion.

The empirical question is whether biofuel production increases the rate of CO2 uptake enough to fully offset CO2 emissions produced when corn is fermented into ethanol and when biofuels are burned.
