Ethanol does produce fewer emissions than gasoline in a direct consumption comparison. By using E85 blends for your automobile, you will enjoy clean oil, lower wear of the engine and a lower need for maintenance. Overall, the transportation sector accounts for approximately 30% of total U.S. energy needs and 70% of U.S. petroleum consumption. Because ethanol fuels are produced from natural products, the amount of fuel that can be produced is reliant on the quality of the growing season. For environmental purposes, ethanol is less harmful than unblended petrol. It requires a lot of cropland space. Cellulosic ethanol is produced from woods, grasses and non-edible parts of the plants. Green Energy 11. As ethanol demands increase, additional farmers will look to convert to the higher paying yields of corn, especially if there are subsidies available for crop loss. Biofuels refer to fuels made from plant materials. Petrol prices in the UAE, along with the rest of the world, have witnessed a rise. There are claims that the long term uses of ethanol are as equally damaging to the environment as conventional fuels. It takes up to 1.4 gallons of ethanol to replicate the mileage that 1 gallon of gasoline can provide. Carbon monoxide production from ethanol fuel is significantly . Disadvantages. Ethanol is also commonly used in high performance vehicles such as racecars because it has a much higher octane rating than petrol. 6 May 2015. Of these, the most commonly extracted and used one is Bioethanol or simply Ethanol and Biodiesel. Reduce Reliance on Imported Oil 9. The first benefit is that biofuels are a renewable energy source and be grown domestically. Disadvantages of Biofuels. There are more than 2,000 fuel stations in the US that already dispense E85 fuel. Also, assess the government's policy regarding ethanol and make a recommendation as to whether you feel use of ethanol is a feasible approach to decreasing the amount of oil used Answer (1 of 4): Ethanol is a relatively low cost alternative fuel that boasts less pollution and more availability compared to gasoline( Motor spirit, Petrol), but there are a number of benefits and drawbacks to this newer form of fuel. The aim of the work is a comparison of two combustion systems of fuels with different reactivity. There is also a worry that the land needed for ethanol production will compete with food production. According to the U.S. Department of Energy, E10 accounted for more than 98% of ethanol sales in 2003. There are disadvantages associated with the use of ethanol as an alternative fuel. Exorbitant Production Costs 2. When water enters the fuel tank you have an issue that needs to be solved immediately, as this will surely cause engine problems. To help ease this burden on our planet's natural resources, many governments are starting to invest in biofuels and other renewable energy sources. Cut Back on Greenhouse Gases 7.

The overall efficiency of a direct methanol fuel cell (DMFC) is 35-60% [109]. Methanol is made from natural gas, coal, and biomass. "Clean" technologies such as wind, solar and hydro power fall into the latter broad category. While it is very unlikely that ethanol will ever replace the worlds main energy source, it will reduce the total amount of oil the country would need to import. Water Use. To create the current levels of ethanol production in the United States, 40% of the corn that is grown is dedicated to this fuel. It is sold in cans starting from one liter, with a variable cost between 2 and 4 euros / l. We could summarize the characteristics of bioethanol in this way: Odorless; Ecological; The primary disadvantage of ethanol is that it requires cropland space in which to grow. Web. The top five producers and users of ethanol in 2005 were Brazil producing 4.35 billion gallons per year, The United States producing 4.3 billions gallons per year, China producing 530 million gallons per year, The European Union producing 250 millions gallons per year and India producing 80 million gallons per year. U.S. Department of Energy's Clean Cities Program, 2 Jan. 2015. Ethanol can absorb water and dirt easily and if those contaminants are not filtered out successfully that can damage the inside of the engine block. Other fuel sources such as hydrogen would require the creation of distribution networks and technology with accompanying establishment costs. Corn pricing is volatile, but it trades consistently higher today than it did in the 1980s. 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 seasonethanol helps reduce emissions. It is a renewable resource and so would reduce the use of non-renewable materials. Since 2014, the widespread use of 10% ethanol fuels has resulted in an increase of 20% of measured CO2 emissions.

Can be used by all vehicles that use gasoline in the United States at concentrations of up to 10% ethanol. The temperature of the fuel is a factor as well. Major environmental problems would arise out of the disposal of waste fermentation liquors. 3. Ethanol burns more cleanly in air than petroleum, producing less carbon (soot) and carbon monoxide. Follow ethanol fuel advantages and disadvantages trends, innovations and developments on echemi.com. Although ethanol fuels do produce fewer emissions than petroleum-based fuels, its incorporation into the US fuel supply has resulted in higher overall emissions being released. The first is combustion of the fuel mixture and the second is combustion in a dual-fuel engine. Bioethanol, often shortened to just ethanol, is a sustainable liquid transport fuel derived from biomass. Biofuels are arguably a potential renewable energy source in the transportation industry as they can be used within current infrastructures and require less technological advances than other renewable alternatives, such as . Alternative fuels are being developed to supplement or even replace fossil fuels. The replacement of fossil fuels with alternative fuels could result in a decrease of CO2 emissions, decrease air pollution and reduce acid rain (Evans, 2007). More focus and research should be done in making biofuels a more prevalent alternative fuel source to oil. 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 seasonethanol helps reduce emissions. Only specially modified motor vehicles ("flexible fuel vehicles") can run on E85. Likewise, its toxicity and corrosiveness are the main disadvantages of methanol [107, 108]. Cost-Benefit 3. Main Menu. Diesel fuel was burned with pure ethanol. Another alternative fuel is methanol. An accelerating global energy demand, paired with the harmful environmental effects of fossil fuels, has triggered the search for alternative, renewable energy sources. That makes it difficult to ship the fuel over long distances unless there are protective technologies incorporated into the distribution networks. Because it is derived from corn, we take up lands that could be used to grow food for ourselves or for livestock and use it grow a fuel product instead. Other forms of ethanol, such as sugarcane ethanol in Brazil, are even higher. Its use has resulted in a net emissions increase. Yeast can produce ethanol contents up to 15 per cent. Here is where an additive that removes water from the fuel comes in. Blends containing this amount of ethanol reduce mileage compared to pure gasoline. E10 and E85 are commonly available blends, with E10 the most widely used around the world. Burning Facility. What are the economic pros and cons of biofuels? Loss in Soil Quality 6.2 2. All these are crops that can be grown. To learn more about fuel economy, GHG scores, and U.S. Environmental Protection Agency smog scores for FFVs, visit FuelEconomy.gov, or see the Alternative Fuel and Advanced Technology Vehicles list. The use of ethanol as an alternative fuel can result in lower pollution emissions compared to fossil fuels, particularly regarding particulates, alkenes, aromatics and carbon monoxide 13. One disadvantage of ethanol fuel is that it has been reported to cause engine burns and corrosion. There is also a cost involved in modifying vehicles to use ethanol or methanol. It is a good alternative fuel because it is carbon . Ethanol production creates jobs in rural areas where employment opportunities are needed. The higher the fuels octane number, the better the fuel and the more resistant it will be to knocking. This was one of the older alternative fuels. Instead of using their lands to produce food products, they convert over to growing fuel products. At present, ethanol is not economically competitive 15, 24. It is a renewable resource and so would reduce the use of non-renewable materials. Really Good Domains Ltd, 12 Feb. 2010. A poor season because of draught or pests could result in fuel shortages, increased pricing, or other issues that have the potential to disrupt our transportation networks. 13. Ethanol is a renewable, domestically produced transportation fuel. Unlike petroleum, ethanol is a renewable resource. Biofuel does produce lower carbon emissions but their production does depend on water and oil. Against this background, the NSW Government has consistently refer to the greenhouse benefits of ethanol as one of the reasons for its decision to require that 10% of all fuel sold is to be ethanol (E10) by 2011. The United States became a net exporter of petroleum in 2020 with exports surpassing imports, although imports of 7.86 million barrels per day remained an important part of balancing supply and demand for domestic and international markets. A good example being ethanol. Fermentation and distillation have been used to produce ethanol for centuries, making it one of the earliest organic compounds to be obtained in nearly pure form. Ethanol blended fuels can significantly reduce our greenhouse gas emissions over their entire lifecycle, from production through to use in the vehicle. The two primary byproducts that come from ethanol production are DDGs and carbon dioxide. Gasification transforms raw lignocelluloses materials which are composed of cellulose, hemi cellulose or lignin into gaseous carbon monoxide and hydrogen. The impact to fuel economy varies depending on the energy difference in the blend used. Cons: This space . Unlike petroleum, ethanol is a renewable resource.
