Compared to fossil fuels, ethanol have some advantages and disadvantages. . TOPIC: Term Paper on Ethanol an Alternative Fuel Assignment . Ethanol. The use of ethanol as a petrol extender causes greater engine wear. Ethanol can be used as a 'petrol extender' in car engines without engine modification in concentrations of up to 24%. The benefits of methanol include: Lower production costs Methanol is cheap to produce relative to other alternative fuels. The term "alternative fuel" was coined by the U.S. Department of Energy in the Energy Policy Act of 1992, and included biodiesel, electricity, ethanol, hydrogen, propane and fuels that were still under development, labeled emerging fuels. 8. Advantages Ethanol is a renewable source, it is made from sugarcane, and corn etc, these substances can be easily replaced in a significant amount of time. While ethanol does have a number of advantages over other alternative fuels and the gasoline it would replace, there are also some disadvantages to consider before making a large-scale switch at the pumps. List of the Pros of Corn Ethanol 1. There are disadvantages linked to the use of methanol and ethanol as alternative fuels. If fuel spills were to occur it is much easier biodegraded or diluted to non toxic concentrations. It is proven to reduce combustion emissions. Burning either fossil fuels or biomass releases carbon . Ethanol is a renewable, domestically produced alcohol fuel made from plant material, such as corn, sugar cane, or grasses. Advantages of Ethanol Fuel 1. One of the major alternatives being suggested is biofuels or biomass, especially ethanol. Alternative Fuels. So, as a fuel, ethanol is cleaner and a renewable source of energy too. The Operating. Implementing more bioethanol would require modifications to many vehicles. Includes short videos on the use of ethanol in professional racing and how one town in. Cars . It may cause food scarcity because of the lucrative prices of bioethanol some farmers may sacrifice food crops for Biofuel production. Ethanol cars. It produces less emissions than gasoline (petrol). "Clean" technologies such as wind, solar and hydro power fall into the latter broad category. Pros: No vehicle emissions other than water vapor. It would have the same issues we see in monoculture. Biofuels provide a cheaper and more sustainable alternative to fossil fuels. Not Profitable to Export 6.3 3. The most commonly used fuel blend these days is E85, which is composed of 85% ethanol and 15% petrol. To help ease this burden on our planet's natural resources, many governments are starting to invest in biofuels and other renewable energy sources. It can be blended with gasoline in varying amounts. the energy required to distill petrol to ethanol is a lot. It is an oxygenated fuel that contains 35 per cent oxygen. . Likewise, its toxicity and corrosiveness are the main disadvantages of methanol [107, 108]. In 2006, the cost of E85 (an 85%: 15% mix of ethanol: gasoline) car fuel was $2.19 compared to the E10 cost of $2.06. In the U.S. most ethanol is used in blends of up to 10% ethanol and 90% gasoline (E10 or "gasohol") to reduce carbon monoxide emissions and prevent air pollution. This green alternative fuel is sustained by its own burning because when CO2 serves as a carbon source for the growth of plants, it will allow the carbohydrates to be fermented. Improved emission levels - less carbon dioxide and soot released as by products. GTU. Biomass production uses a lot of water 5. To use pure ethanol in car engines, modification would . The fuel efficiency rates of biofuels like ethanol are up to 33% less than when we use refined gasoline. 2. Ethanol is also available as E85 (or flex fuel)a high-level ethanol blend containing 51% to 83% ethanol, depending on geography and seasonfor use in flexible fuel vehicles. A dual-fuel gas station (ethanol and petroleum) in Sao Paulo, Brazil Goals for the project are: To reduce drop-in biofuel costs Vehicles capable of using E85 fuel are called flex-fuel vehicles because a single fuel tank can hold any mixture of gasoline and ethanol fuel, up to 85% ethanol. The advantages of ethanol use are: The fuel can utilise existing distribution outlets. If you turned oil palm into a fuel, then you would receive 635 gallons per acre. Other fuel sources such as hydrogen would require the creation of distribution networks and technology with accompanying establishment costs It is a renewable resource and so would reduce the use of non-renewable materials. In the second part the cost perspective is . Due to pressure to become energy independent and more environmentally aware, alternative fuels like ethanol have become a significant source of fuel. as well as the advantages and disadvantages of ethanol as a fuel of the future. Air pollution, climate change, drilling pollution, nonrenewable. Advantages And Disadvantages Of Bioethanol. Another disadvantage highlighted by opponents is the economic aspect of using the fuel. Biofuels Advantages And Disadvantages: A significant problem facing the world today is the amount of power generated by harmful fossil fuels, such as oil and coal. Pros And Disadvantages Of Sulfur Dioxide. Advantages and disadvantages of using Ethanol instead of petrol and other kinds of academic papers in our essays database at Many Essays. Ethanol tends to be cheaper than petrol, so blending the two successfully could be cheaper. 2. As ethanol is available as E85, a high-level ethanol blend, as its a alternative fuel that can be used in flexible fuel vehicles that is a vehicle type that has an internal combustion engine and runs on either E85 or gasoline. Increased energy security Methanol can be manufactured from a . It has a very high octane number (above 100) and a very good flame speed. Ethanol and methanol are alcohol fuels which can be distilled from a wide variety of biomass feedstock. It improves mileage. Burning a liter of ethanol produces 34% less energy than burning a liter of petrol. Ethanol is mainly made from carbon dioxide, water . The only advantage that biomass provides when looking at this specific disadvantage is the option to reduce accumulated waste levels. Ethanol Biomass is an attractive fuel source because it's renewable and easy to grow. It provides the world with a greener method of producing fuel. Unless a better alternative is provided, ethanol remains the only choice when we run out of fossil fuels. 1. After a period of operational experience lots of technical and safety queries will be solved, most probably influencing further decline in investment costs. This work presents a short overview of the possible use of methanol and ethanol as lternative fuels in shipping. 3. Because the production process involves cultivation, processing, and distilling, it does not get rid of its fossil fuel impact immediately. METHANOL AND ETHANOL AS FUELS 1-888-302-2840; 1-888-422-8036; Home; . The world is moving towards alternatives to our current fuel sources. hybrid disadvantages. Some people also suggest that the emissions from petrol-based fuels used in producing the grain exceed the ethanol's own emission benefits. The use of ethanol can reduce our dependence upon foreign oil and reduce greenhouse gas emissions. A solvent is a substance that can wash away dirt, which means it can clean your car engine making it last longer. Biomass and biofuels made from biomass are alternative energy sources to fossil fuelscoal petroleum and natural gas. plug-in hybrid disadvantages. Ethanol has a marginally positive energy balance Ethanol isn't distributed throughout the nation Ethanol is less efficient than gasoline and cuts mileage by about 4% Production of ethanol raises corn prices Ethanol tends to evaporate and cause smog One gallon of ethanol won't go as far as one gallon of gasoline Go to Production of Corn Ethanol Here are the advantages of using ethanol-mixed fuel instead of pure gasoline: Cheaper Oil Alternative. Rammed earth techniques of durable construction have been around for decades. List of the Advantages of Ethanol 1. Disadvantages of the potential use of Ethanol Alternative fuel to replace petrol with ethanol, you will have to remove a lot of land and make those lands as farms of crops. But what are the advantages and disadvantages of biofuels? fuel alternatives will be needed at some time and it is prudent to look at the alternatives and weigh the advantages and disadvantages. It contributes to deforestation 4. In Brazil, many cars run on E85 ethanol fuel, or 85 percent ethanol. By using E85 blends for your automobile, you will enjoy clean oil, lower wear of the engine and a lower need for maintenance. Ethanol is a renewable energy source because it uses sunlight as a source for its production process. The energy content of ethanol is much lower than that of petrol gasoline. 4. The main reason why the world needs an alternative source of fuel is because the existing resource is running out; crude oil is a non renewable resource. FIRST INTERNATIONAL AFRICAN BIO-FUELS SEMINAR - 14.12.2009 to 16.12.2009 . Regardless of using bio-butanol as pure vehicle fuel or gasoline . The alcohol fuel has more advantages compared with fossil fuels, and they are given below: Both lower molecular weight alcohols can be made out of indigenous energy resources such as biomass, coal and natural gas, which are available with low cost. Improved safety Methanol has a lower risk of flammability compared to gasoline. These disadvantages include: Price Fluctuations The prices of ethanol vary and fluctuate greatly. Ethanol is not an alternative fuel to standard gasoline. Regular engine maintenance can significantly drain your capital reserves. ALTERNATIVE FUELS FOR I.C. If we find an alternative gas in place of fossil fuels, then it not only reduce So2 but other harmful gasses as well. Ethanol does burn cleaner than gasoline, which is another one of the advantages of ethanol fuel heavily promoted by its proponents. Disadvantages of Ethanol Even though ethanol fuel comes with multiple benefits both to the environment and the economy, it also has several drawbacks. Low Fuel Economy 6.4 4. And because your engine is able to convert the fuel into more kinetic energy, you get to use less fuel but achieve more mileage. On one end of the spectrum, the average acre of corn produces 18 gallons of ethanol. Biofuels don't produce the same energy levels as refined fossil fuels. Advantages Ethanol (ethyl alcohol) is a renewable resource that is easy to manufacture and process. Therefore they are a renewable cooking energy alternative, which are highly convenient to use. E85, a blend of 85 percent ethanol and 15 percent petrol, also has fewer volatile components than petrol, which means fewer gas emissions from evaporation. This report states, "Ethanol remains the highest-octane, lowest-cost motor fuel on the planet." Additionally, in 2019, the U.S. Department of Energy (DOE) allocated $73 million for 35 bioenergy research and development (R&D) projects. The advantages of ethanol use are: The fuel can utilise existing distribution outlets. 1. According to Pimental, the effective cost of ethanol fuel is $1.74 whereas the cost of gasoline is only $0.95. Ethanol products create fewer greenhouse gas emissions than the other fuels that we currently use. The use of pure ethanol and methanol is limited in colder climates by their low vapour pressures (Baird & Cann, 2008). Other fuel sources such as hydrogen would require the creation of distribution networks and technology with accompanying establishment costs It is a renewable resource and so would reduce the use of non-renewable materials. It used to be used in vehicle concentrations as high as M85, but it is not commonly used in such high blends anymore because automakers are not developing methanol powered vehicled. Advantages of using alcohol as a fuel. Blends containing this amount of ethanol reduce mileage compared to pure gasoline. Ethanol-blended fuel as E10 (10% ethanol and 90% gasoline) reduces greenhouse gases by up to 3.9%. Loss in Soil Quality 6.2 2. These fuels may be used in a dedicated system that burns a single fuel, or in a mixed system with other fuels including traditional gasoline or . This was one of the older alternative fuels.
