Corn ethanol is certainly a tempting fuel. Contents. Cellulosic feedstocks have many advantages over using corn to produce ethanol. The corn ethanol boondoggle threatens to be far, far worse. Ethanol is a renewable, domestically produced transportation fuel. Positive Net Energy Balance - Corn-based ethanol has a positive net energy balance of 1.06btu per gallon for 1.00btu of energy used without ethanol by-product credits. . However, even though corn ethanol is renewable, there are many pros and cons to consider before adopting it as a staple fuel source. Comments from expert scientist: There is substantial background information on the subject, extending beyond cellulosic ethanol and offering a sincere, objective, and concise discussion on the pros and cons of different options to produce biofuels. It reduces carbon monoxide emissions by up to 30%. Now, as we discover that our fossil fuels are running low, some look to corn-based ethanol as the solution to cleaner, renewable energy. And because a wide variety of crops can be used, they can be grown in a wide variety of geographic locations--even on marginal lands--and can, therefore, be more abundant. "Advantages and Disadvantages of Biofuels - Conserve Energy Future." When we look at the pros and cons of ethanol fuel, there are some very specific environmental benefits to consider. See Related: What is Nuclear Energy? The Pros and Cons of 8 Green Fuels. Even though biofuels might be a promising alternative energy source in the future, there are still plenty of downsides related to it. Thus not affecting the food markets. Ethanol Benefits and Considerations. The future of ethanol now rests on the successes or failures of cellulosic ethanol since cellulosic ethanol is where the benefits of biofuels finally begin to outnumber the costs. It has a lot of good attributes, but it also has some drawbacks that hinder it from becoming widely used as a sole fuel source. Cellulosic ethanol is a type of biofuel produced from lignocellulose, a structural material that comprises much of the mass of plants and is composed mainly of cellulose, hemicellulose and lignin.Popular sources of lignocellulose include both agricultural waste products (e.g. “Cellulosic” ethanol can also be made from wood or paper waste as well as specially grown grasses such as switchgrass or from agriculture residues. It burns much cleaner than regular gasoline. One such alternative is what is known as cellulosic ethanol that can be produced from grasses, waste from the wood and paper industry, or almost any plant source. Conserve Energy Future. 8 Central Pros and Cons of Algae Biofuel. Being a clean fuel and also a renewable energy source, ethanol features today more advantages than disadvantages. Pluses: Sugar cane yields more ethanol per acre than corn, and it requires less energy to produce; hence, it is regarded as greener than corn ethanol. There are wage and employment benefits to look at with this commodity, but it also requires governmental interventions to establish the product as viable because of the expensive production processes. If cellulosic ethanol becomes a widespread fuel, it would be a boon for agricultural regions—while nations with little arable land would be left out. Pros Greenhouse Gas Reduction - Corn-based ethanol reduces GHG emissions by 18% to 29% per vehicle mile traveled compared to petroleum-based fuels. It has been already proved that ethanol is a clean fuel that produces no pollution in the environment. It's more available than corn or any other source of ethanol, or for that matter, any existing source of fuel. There is corn ethanol and cellulosic ethanol, and there is a significant difference between the benefits and drawbacks of these two. 17 Nov. 2016. US - Filling fuel tanks with cellulosic ethanol instead of gasoline or corn-based ethanol may be even better for human health and the environment than previously recognised, according to new research from the University of Minnesota. Feb 19, 2019 Jun 2, 2015 by Brandon Miller. Advantages of Ethanol. Cons. Because cellulosic crops are not used for food, there is inherently less price volatility. The chemical compound is the same whether the ethanol is produced from switch grass, sugar cane, biomass, or another cellulosic feedstock. Cellulosic ethanol - is it a better ethanol? Go to Pros and Cons of Corn Ethanol Powered by Create your own unique website with customizable templates. Ethanol fuel can be truly beneficial especially if the overall effect in the ecosystem is included in the equation. Web. Alternative renewable energy sources must be found and used, and methanol fuel is … They predicted that ethanol would become the world's fuel supply. They concentrate on the likely future—cellulosic biofuels made from whole plants such as fast … Advantages of Ethanol. Ethanol made its debut in the early 1970s, and by the late 1980s, ethanol was beginning to be used for fueling cars (Fuel-testers, 2012). Whether used in low-level blends, such as E10 (10% ethanol, 90% gasoline), E15 (10.5% to 15% ethanol), or E85 (flex fuel)—a gasoline-ethanol blend containing 51% to 83% ethanol, depending on geography and season—ethanol helps reduce emissions. Using a 10% blend with standard gasoline can lower the carbon monoxide emissions from a vehicle by up to 30%. The conversion rate is lower as compared to the first-generation biofuels; hence, cellulosic ethanol usually serves only as a gasoline additive. We can produce cellulosic ethanol through sugarcane bagasse, which is a waste product that comes out during sugar production. In areas where ethanol is used, there is a lack of filling stations and this means that drivers continue to use petrol. The first major benefit of cellulosic ethanol is emissions reduction. Cons Of Ethanol Fuel. Corn crop residue model - pros and cons of different collection models. The widespread use of ethanol as an energy source for cars is hampered by the lack of adequate infrastructure in areas that support ethanol production. In this article, the pros and cons of biofuels are examined. The low mileage would simply be enough sacrifice to save the only place where humans can survive. The pros and cons of the various feedstocks and the pre-treatment processes of the feedstock, (the first step before you use a similar process for making corn ethanol today) are all being evaluated in various research efforts that are underway and in … Corn crop residue for use as a feedstock could provide corn growers a new source of income in Iowa, where POET-DSM Advanced Biofuels and DuPont Industrial Biosciences are expected to begin producing cellulosic ethanol … A Pros and Cons Analysis. Cellulosic fuels (e.g. Sugar isn't a food staple, so making ethanol from it hasn't driven up food prices as has the production of large amounts of corn ethanol. Congress created the Renewable Fuel Standard to reduce the emission of greenhouse gases and up to this day, the issue on corn ethanol has remained contentious. 1. corn stover or wood chips) and grasses like switchgrass and miscanthus species. Big square baler harvesting wheat straw for production of cellulosic ethanol. Now in the midst of the green movement of the 2000s, ethanol can be found in over 90 percent of gasoline at public gas stations (Fuel-testers, 2012). Ethanol is a very useful biofuel for mankind because it can lower the level of emissions released by the transportation sector, but there are also a few downsides related to this alternative fuel, mostly created by its high price and … The pros and cons of biofuels. The Executive Summary of the IAASTD Synthesis Report states: ... 2.4 Next generation biofuels such as cellulosic ethanol and biomass-to-liquids technologies allow conversion into biofuels of more abundant and cheaper feedstocks than … The growing need for alternative and renewable energy has spurred plenty of research into other sources than what the world is already using, one of which is algae. Audio Lesson. Is a Fuel that Reduces the Level of Greenhouse Gas Emissions Released by Vehicles. The pros and cons of corn ethanol attempt to balance specific environmental benefits with higher consumer costs. Brain, Marshall.
