Using viable lands for biofuel production and other alternative energies when food sources may be needed could mean that humans go hungry because of the need for fuel. Global warming: Burning of fossil fuels is believed to be one of . From simple essay plans, through to full dissertations, you can guarantee we have a service perfectly matched to your needs. Under certain driving conditions, such as low speed city driving, propane engines will generate less than 4% of the NOx that a comparable diesel engine would produce. It's environmentally friendly. 1) A Fuel Supply That Never Runs Out. Even clean-burning natural gas is at a disadvantage to what renewable energy sources can provide. However, the amount of available organic feedstock from which RNG can be made is finite. Alternative fuels include gaseous fuels such as hydrogen, natural gas, and propane; alcohols such as ethanol, methanol, and butanol; vegetable and waste-derived oils; and electricity. This means that, like electric cars, hydrogen-powered cars are a lot quieter than vehicles that are powered by conventional engines. The alternative energy industry offers the creation of bio-based fuels like ethanol and algae biofuel. The land area required to generate sufficient alternative fuel to meet demands however, may compete directly with agriculture requirements, water use, may cause pollution from the use of herbicides and pesticides, and could result in the destruction of natural habitats and a decrease in biodiversity (Evans, 2007; Giampietro & Ulgiati, 2005). 2. Additionally, higher energy density can be achieved in the engine due to a lower stoichiometric air to fuel ratio (Brown, 2003; Demirbas, 2008).This may produce enhanced engine efficiency and elevated power outputs in ethanol fuelled vehicles when contrasted to petroleum fuelled vehicles. Regardless of how quickly these industries are progressing, they are the collective wave of the future. Operators of city buses, dumpster trucks and other commercial vehicles have saved millions of dollars by converting their fleets to run on CNG. Wind power provides us with an advantage in that it produces no pollution that contaminates the environment. The varying climates that are found throughout the geographic regions of our world dictate the types of crops we can cultivate. (Last Updated on June 16, 2020 by Sadrish Dabadi). From 2016 to 2021, its use has increased by over 230%. 2. Advantages of Gaseous Fuels: Gaseous fuels are highly combustible and produce a lot of energy per unit volume. When a freak winter storm struck Texas in February 2021, the states power grid couldnt handle it. Hydrogen fuel sources can be installed the same way traditional gasoline fuel sources are installed on a vehicle. The kettle could be placed on a trailer behind a vehicle, and from there piped to the vehicles engine. Unlike other petroleum fuels, propane is nontoxic and presents no risk of soil or water contamination. The fuel itself is generally non toxic and biodegradable (Demirbas, 2008; Shahid & Jamal, 2008). Except for solar farms, you dont have to face such limitations with alternative energy resources. All ongoing fuel consumption with an alternative fuel is either free of harmful pollutants or has a very minimal effect. Ethanol blending is extremely common. LNG stations typically serve long-haul trucking applications. Though we seem to enjoy the advantages offered by them, there are also disadvantages of fossil fuels. Expensive direct costs required for the production of ethanol can include fertilisers, pesticides, irrigation, fuels and electricity as well as machine or equipment maintenance (Vadas, Barnett & Undersander, 2008). It has Low engine emissions. The Pros of Alternative Fuels 1. LNG facilities contain specialty cryogenic equipment, and their use requires certain safety precautions because of the extremely low fuel temperature. How do you feel about the subject? Power plants based on reciprocating engine power generators, for example, can start their engines on natural gas. Wind turbines must be manufactured and installed. The production and use of biodiesel is associated with some adverse environmental effects and it is not economically competitive at present, indicating that it is not a viable alternative. Transporting natural gas releases methane which is 28 to 34 times more potent of a greenhouse gas than carbon dioxide. Generally, this process The USA and Brazil are presently the two major producers of bioethanol (Ragauskas, et al., 2006). Electricity for the home can be generated from wind, solar, or even nuclear power instead of coal. Renewable feedstocks, like agricultural waste products, spent cooking oil and animal fats, can also be used to make propane. It creates a new employment section. Discard in use of these fuels will definitely reduce pollution. List of the Advantages of Alternative Energy 1. 1. On the plus side, ethanol can be synthesized and does not need to be drawn from the ground or imported into the U.S. On the other hand, ethanol has less energy per unit volume, meaning that cars get lower gas mileage. So do solar panels. Can be blended with gasoline to create E85, a blend of 85% ethanol and 15% gasoline. Another option is to process food waste into biogas and RNG. 1. Lifestyle - What are Biofuels? These additional factors often are more localized. The advantages and disadvantages of alternative fuels are debated in the editorial pages of major newspapers in the United States and worldwide every day. Workers can plant trees, work the soil, retrofit older technologies, and invent new technologies not yet even dreamed. All work is written to order. In America, we're embracing renewables at a remarkable rate, with clean energy now outpacing . They are almost universally used in motor vehicles of all kinds, in power generation, and more. Stay ahead with the latest in new technologies, products, industry trends and news. Alternative fuels are also an option for stationary internal combustion engines. Hybrid combination-fill stations also exist. This is not something we can immediately remove ourselves from unless we are willing to accept potentially dire financial consequences. 2. General Use of Alcohols- Ethanol Alcohol-based alternative fuel produced by fermenting and distilling starch crops or cellulose Most commonly used to increase octane and improve the emissions quality of gasoline. Biofuels, in contrast, release the carbon which was taken from the atmosphere by the crops that they are made from. This is the main reason why they are still the major energy supplier of the world. There are numerous problems currently associated with the manufacturing of biofuels such as the vast amount of land, labour and water required. Whether you are in marine, mining, rail, power generation or another sector, you may be wondering if your equipment is compatible with different alternative fuels. Owners of dual-fuel vehicles can thus run on CNG, and, if no CNG fueling station is nearby when the gaseous fuel runs out, continue driving on gasoline. They can be used anywhere that there is generous source of sunlight. Petroleum can be accessed through fracking techniques. Kevin Beck holds a bachelor's degree in physics with minors in math and chemistry from the University of Vermont. Crystal Lombardo is a contributing editor for Vision Launch. We're here to answer any questions you have about our services. As the younger generations go through advanced schooling this could change, but the transition could take decades instead of years to complete. RNG is, chemically, nearly identical to natural gas obtained from fossil resources. She earned her Master's Degree in Energy and Earth Resources from Austin Jackson School of Geosciences in 2010, and a Bachelor's Degree in Environmental Science from State University of New York College of Environmental Science and Forestry in 2008. Here are some additional benefits: Shelf life: Unlike gasoline and diesel, natural gas and propane have an unlimited shelf life, as do hydrogen and ammonia-based e-fuels. If the Earth is really going to run out of coal, oil and gas in the years to come, what are the leading candidates for shepherding world society into a new, "alternative" energy economy? Many natural gas fuel suppliers are also willing to subsidize the fueling infrastructure and recoup the cost over several years with a slightly higher fuel price. This makes installing propane fueling stations easy and cost-effective. The exhaust contains about 50 percent less nitrogen oxides. It is a very green friendly fuel that can help to halt and even in some cases reverse our current rising levels of green house gas that oil has had a major contributing factor in. Renewable energy technologies could produce many jobs in the future. Biofuels are definitely cheaper than fossil fuels. Alternative fuels are not just for road vehicles. These can include nitrogen and phosphorus leaching that can lead to the loss of biodiversity and the release of nitrous oxide, a greenhouse gas (Hill, et al., 2006). Traditional fossil fuels can generate large quantities of electricity. The industrial production of RNG is experiencing a boom driven by a growing demand. Time-fill stations are best suited for heavy vehicles with large tanks that refuel nightly at a central location. You can check out what are power-to-x and e-fuels to learn more. First, it's good to look at the advantages of using renewable energy sources instead of burning fossil fuels. It is available in compressed form at about 1,500 public and private fueling stations in the United States. Natural gas prices tend to avoid the cyclical price fluctuations that petroleum-based fuels such as gasoline experience. The balance between existing sources and alternative sources can solve many scarcity problems. 1.Title My title is using of the hydrogen as a fuel for cars as a fuel cell method and also i analysis the advantages and disadvantages of the research. 3. This is why biofuels are thought of as net-CO2 free fuels. 2.Objective The objective 2. In many cases, RNG is made opportunistically at facilities which generate a feedstock as a by-product of their operation. France's success in cutting down emissions is a clear example of some of the main advantages of nuclear energy over fossil fuels. Many fleets interested in this technology invest in a private fueling infrastructure so they can fuel up onsite before heading out on routes for the day. It can be used in the form of compressed natural gas (CNG) or liquefied natural gas (LNG) to fuel cars and trucks. Due to cooler intake, volumetric efficiency of engine running on alcohol is good. Overview Deeper wells and mines in more hostile environments equals more expensive energy - not to mention an even higher cost to the environment. 2022 Cummins Inc., Box 3005, Columbus, IN 47202-3005 U.S.A. Sign up below to receive the latest in technologies, products, industry news, and more. Lower carbon emissions make them a safer alternative to preserve atmospheric quality and lower air pollution. At present, commercial biofuel production is a controversial issue that is still relatively new. Renewability Is an Advantage It takes a very long time for fossil fuels to be produced. Businesses who do choose to build a Compressed Natural Gas (CNG) fueling station on their premises have several options. It is safe, abundant, and clean to use when compared to fossil fuels. The Advantages of Renewable Energy Resources. Using an alternative fuel can be a good way to reduce carbon emissions. Alternative energies are sources outside of fossil fuels that can power your economy. We cannot control nature, but if we reduce the amount of energy we consume, we wont need a big supply. What are the disadvantages of biofuel energy? Fremont, CA: Apart from fossil fuels, wind energy generation has contributed highly to meeting the energy needs and concerns of people across different geographical locations. 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. Biodiesel - Usually, it costs $5.53 to $6.38 per gallon. Hydrogen fuel sources can be installed the same way traditional gasoline fuel sources are installed on a vehicle. Advantages of Fossil Fuels: Large storage: High Efficiency: Easily Transportable: Create Employment: Disadvantages of Fossil Fuels: Environmental pollution: Non-Renewable Energy Source: Harmful to Plants and Living Species: What is fossil fuel? As more and more biofuel is created there will be increased energy security for the country producing it, as they will not have to rely on imports or foreign volatile markets. Alternative fuels present a variety of other advantages. Here are some of the top benefits of going green: Renewable energy won't run out Renewable energy has lower maintenance requirements Renewables save money Renewable energy has numerous environmental benefits Renewables lower reliance on foreign energy sources List of Advantages of Alternative Energy Zero Pollution Renewable Resource Use of Land Resources Makes Real Economic Sense Creation of Bio-based Fuels Stabilized Global Energy Prices Less Maintenance of Facilities Good for Regional Areas List of Disadvantages of Alternative Energy Weather Affects Energy Supply Low Efficiency High Cost There are over 23 million natural gas vehicles in the world, including over 175,000 in the United States. Type above and press Enter to search. Ethanol burns more cleanly in air than petroleum, producing less carbon (soot) and carbon monoxide. 12. Fossil fuels are cheap, reliable, and widely available. RNG also needs to be transported and distributed to end-users. Biodiesel also thickens greatly in cold temperatures and burns poorly under such conditions. As the supply of biodiesel and bio jet fuel grows, so will the supply of renewable propane. Fuels that have been extracted from plants and crops are known as biofuels. What are the economic pros and cons of biofuels? 2022 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. In summary, propane is a great option for clean, environmentally-friendly vehicles. She worked as an Energy Supply Analyst from 2011 to 2017 in Bounce Energy and then as a Research and Energy Consultant at GE Renewable Energy from March 2017 to February 2020 . LNG stations are less commonthere are about 60 in the United States. To begin with, what is a fuel? It burns clean and it can help reduce greenhouse gas emissions. What are the advantages and disadvantages of using alternative fuels? All of this makes propane vehicles intrinsically clean. You fully depend on external factors such as weather conditions. It is being used increasingly as a fuel source for fuel-cell vehicles. First and foremost, nuclear energy is clean and it provides pollution-free power with no greenhouse gas emissions. Traditionally, internal combustion engines run on liquid fuels. Propane - the price of propane can change throughout the year but it can cost around $2.00 to $2.75 per gallon but some companies may charge you . This fuel provides natural gas engines with great economic benefits. There isn't currently enough electricity to power the world, and developing it isn't consistent enough. They can claim that they are, effectively, using RNG. As a result, users and producers can rely on an extensive mid-stream and down-stream infrastructure. These stations receive natural gas at a low pressure from utility companies and the gas is compressed directly into the vehicle. Fact is that every country has at least one fossil fuel energy source . 4) A Cheaper Form of Electricity. Thats a 20% increase compared to the previous year. SynFuels protect the filter and the engine. Biofuels being environment-friendly is one advantage that beats all pros and cons. Biodiesel production is deemed renewable (Shahid & Jamal, 2008). As oil prices become increasingly more expensive, biofuels do become more economically viable. There are also other factors such as fuel availability, use case, and local regulations that you need to consider. This has contributed to global warming. Since the captured sunlight needs to be stored right away, you require large batteries. The news is rife with earnest chatter about climate change, "clean" or "renewable" energy, the environment and the need to rein in the burning of fossil fuels in order to stave off ecological and other crises in the coming decades. The disadvantages of hydrogen as an alternative fuel are, Hydrogen is expensive. Lets look at the real advantages and disadvantages of switching to renewable energy sources. By James D. Agresti Geothermal energy is considered the best. The disadvantages of natural gas as an energy source include: Natural gas is still a fossil fuel. To help ease this burden on our planet's natural resources, many governments are starting to invest in biofuels and other renewable energy sources. Storage of hydrogen gas is hard. Compared to other biofuels, however, biopropane currently remains a niche-use fuel which is produced in relatively small quantities and has limited availability. Not every nation has access to vast oil reserves that may be needed for traditional fuels. The advantages of fossil fuels are as follows: Fossil fuels have a very high calorific value. With so many positive aspects, there are some reasons why renewable energy can be troublesome. U.S. Life Expectancy Fell With Covid Vax Rollout, NY Times Blames a Lack of Vaccination and White People, 1913 The Year the Republic Was Overthrown, Four Things We Should Teach Children About the Constitution, Uninformed Consent (Full Documentary, Part 1 & 2). The California State University: Alternative Fuels: Betting on Batteries, MIT: Spinning Science: Alternative Fuels: The Big Picture. Conclusion , 13. Propane is also nontoxic, is not a hazard to plant or animal life and will not contaminate the environment. So, how much RNG can be made exactly from existing and potential resources? The structure or foundation of an alternative fuel often involves the consumption of a fossil fuel. Low aldehyde emission than alcohols. RNG can be fully interchangeable with traditional natural gas. For example, solar cells may provide varying amounts of power that depend on factors like cloud cover. Study for free with our range of university lectures! Fossil Fuel: Advantage: They're efficient in generating electricity. Jhawar has extensive global experience, with roles based in the Middle East, India, Europe and the US. Instead, nuclear power plants release clouds full of harmless water vapor, which is infinitely better for both humans and the environment. They are a much cleaner source of energy than conventional sources. It is usually obtained by refining crude oil or wet natural gas. These factors support the idea that biodiesel is an alternative form of fuel; however this does not make it a viable alternative to petroleum-based diesel. Thats something which hydrogen producers and users can only dream of. The information you are looking for is on For example, vehicles running on a fuel known as wood gas were widely used during World War II. Puneet Singh Jhawar is the General Manager of the global natural gas business for Cummins Inc. Wind speed is notoriously inconsistent, and hydro power can be both inefficient and damaging to the environment in the form of flooding. Unlike petroleum, ethanol is a renewable resource. The energy created from alternative fuels does not require a lifestyle change. 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 . Biofuels, which may be used as an alternative to petrol, come with various advantages: FUEL-EFFICIENCY Use of biofuels can help lower the harmful emissions by vehicles using fossil fuels . Biopropane is often co-produced along with biodiesel via complex chemical processes. Once the infrastructure for harnessing renewable resources is set up, there is almost zero maintenance required. Biodiesels must be blended with fossil diesel to be used in standard compression ignition (CI) engines. The controversies over what must be taken as alternative energy still exist and some of the alternative energy advantages and disadvantages. An important advantage of the alternative engine is the use of liquid fuels of great calorific value. One of the main advantages of biofuels is their relatively low cost. Biodiesel is a non-toxic fuel producing lower emissions as compared to fossil fuels when burnt. There is no need to convert the tank to use it. Following this, the advantages and disadvantages of alternative fuels will be considered. Businesses who wish to switch their vehicles to RNG often opt to construct a fueling facility on their own premises. 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). 1. On the other hand, biofuels do not release this carbon and they are thus considered clean fuels. Biofuels are less inflammable as compared to fossil fuels. Propane engines grant a set of environmental benefits to users. Biodiesel can work as an alternative form of fuel and can reduce our dependence on foreign suppliers of oil as it is produced from domestic energy crops. Alcohol has low sulphur content in fuel. They needed to be fueled by people and they can't be naturally fueled. As the name implies, they are for use in diesel vehicles. The global society we have today was built because of technologies that were created around oil. Hydrogen cars also give the driver excellent mileage compared to regular gasoline cars. The use and manufacturing of alternative fuels in Australia will then be assessed.

Several types of alternative fuels with a proven track record are available and, when deployed judiciously, can help businesses meet their environmental and cost reduction objectives. Propane vehicles have extremely low emissions of air pollutants and substantially lower GHG emissions than other vehicles running on other fossil fuels. There are about 1,500 public and private stations dispending compressed natural gas in the United States, compared to over 150,000 gas stations with gasoline or diesel. Natural gas, a fossil fuel composed of mostly methane, is one of the cleanest burning alternative fuels. Alternative fuels such as methanol, ethanol and biodiesel have numerous advantages and disadvantages regarding environmental and societal impacts. Fixed costs tend to include land charges, wages for labourers, insurance and depreciation of assets such as equipment and buildings (Vadas, Barnett & Undersander, 2008). Liquid fossil fuels are convenient and affordable, but they are not the only fuels that engines can burn. Alternative fuels are a way for societies to reduce or eliminate the use of fossil fuels for daily needs. Alternative fuels are being developed to supplement or even replace fossil fuels.
