Hydrogen Fuel - Advantages and disadvantages - Boiler Central This means it still produces emissions that contribute to climate change. Alternative fuels are also an option for stationary internal combustion engines. So, the net consumption is the same even after accounting for all emissions. Global population is continuing to dramatically rise and the increase in economic development, particularly in China and India, over recent decades has contributed to increases in energy consumption (Hillstrom & Hillstrom, 2003). Switching to natural gas engines comes with many benefits, but lets focus on their refueling infrastructure. They generate significant amounts of electricity/energy with relatively little cost. Our academic experts are ready and waiting to assist with any writing project you may have. Today, few vehicles run on wood gas, but many other alternative fuels are available, and several more are being developed. 12 Advantages and Disadvantages of Fossil Fuels - Vittana.org You fully depend on external factors such as weather conditions. 11 Advantages and Disadvantages of Renewable Energy Some roofs might not be strong enough to hold or big enough to fit the total number of panels you need. The production of biodiesel from crops, such as soybean, can result in adverse environmental effects. First and foremost, nuclear energy is clean and it provides pollution-free power with no greenhouse gas emissions. The alternative fuels that are currently prevalent throughout the world are ethanol and biodiesel (Vadas, Barnett & Undersander, 2008; Groom, Gray & Townsend, 2008; Gupta & Demirbas, 2010). In certain industries, additionally, non-carbon emissions pose a specific set of problems. Most of the RNG supply is sent to states with low carbon fuel credits for natural gas. This is why propane vehicles are often not allowed to use underground car parks. Natural gas is abundant, relatively cheap, and widely available. 2.Objective The objective 5. Here are several important benefits of using renewable energy: 1. Fast-fill fueling stations receive low pressure fuel from the local distribution network. Wind turbines must be manufactured and installed. Over his 14-year career at Cummins, Jhawar has cultivated successful relationships with a number of Cummins largest customers. It is a renewable resource and so would reduce the use of non-renewable materials. Stationary engines are commonly used in industrial applications such as oil and gas extraction or power generation. Overview Advantages and Disadvantages of Biodiesel Fuel Generally, this process The USA and Brazil are presently the two major producers of bioethanol (Ragauskas, et al., 2006). Read about energy technologies and trends on our Energy IQ Hub. 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. Time-fill stations tend to be custom-designed. 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. What are the advantages of using biofuels? A. The power field. 4. There are however, a number of drawbacks related to alternative fuels which may inhibit them from completely replacing fossil fuels without technological or genetic advancements (U.S. Congress, Office of Technology Assessment, 1990). Right now, only California, Oregon and Washington state offer these credits, so suppliers prioritize shipping fuel to them. That percentage increases in California, where its 98%. For most engines, no modification is required. Biodiesel production is deemed renewable (Shahid & Jamal, 2008). Similarly, solar and hydroelectric energy offer similar benefits as well, but to a lesser extent. It can be produced by electrolysis of water that requires electricity. The advantages of renewable energy have been known for a very long time - such as cleaner air, lower carbon emissions, the conservation of natural resources, and substantial long-term savings. Modern propane engines produce extremely small amounts of NOx. It can be difficult to produce the same amount of energy as non-renewable resources. Alternative Energy Advantages and Disadvantages | 2020 Read This requires the nations that do not have these reserves to be dependent, in part or in whole, on the actions of others. Some waste management companies, for example, gather biogas emanating from landfills they manage. They can produce deadly nuclear waste, which can destroy living organisms and severely affect the surrounding areas for years. Do you have a 2:1 degree or higher? Adopting the use of an alternative fuel can help further one or more of those objectives. Although only are only a few RNG companies, more are seeking to increase production. It is not by chance that RNG is so popular in the state. PDF | On Sep 6, 2017, Nabel A. Negm and others published Biofuels from Vegetable Oils as Alternative Fuels: Advantages and Disadvantages | Find, read and cite all the research you need on ResearchGate 1. Kevin Beck holds a bachelor's degree in physics with minors in math and chemistry from the University of Vermont. Thats a 20% increase compared to the previous year. There are over 23 million natural gas vehicles in the world, including over 175,000 in the United States. Burning fossil fuels releases carbon into the atmosphere that was previously stored underground. You can check out what are power-to-x and e-fuels to learn more. As the supply of biodiesel and bio jet fuel grows, so will the supply of renewable propane. Alternative fuels can replace traditional fuels right now. Once the engines are running, they can be switched to biodiesel, allowing net CO2-free operation. 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). Besides CO2, internal combustion engines emit other gases in their exhaust. Suitable for the society. In many cases, RNG is made opportunistically at facilities which generate a feedstock as a by-product of their operation. LNG facilities contain specialty cryogenic equipment, and their use requires certain safety precautions because of the extremely low fuel temperature. Copyright 2003 - 2022 - UKEssays is a trading name of Business Bliss Consultants FZE, a company registered in United Arab Emirates. It is available in compressed form at about 1,500 public and private fueling stations in the United States. Biofuels being environment-friendly is one advantage that beats all pros and cons. RNG is made from biogas, which is the product of a biological process known as anaerobic fermentation. Hydrogen fuel sources can be installed the same way traditional gasoline fuel sources are installed on a vehicle. The California State University: Alternative Fuels: Betting on Batteries, MIT: Spinning Science: Alternative Fuels: The Big Picture. By developing alternative fuels to replace traditional fuels, then the possibility of energy independence appears. Using a fuel with a greater ethanol or biodiesel content can also be effective. As a result, users and producers can rely on an extensive mid-stream and down-stream infrastructure. It also delivers the power and range required for many commercial vehicle applications. Biodiesel is obtained from the oil in a variety of seed plants, a large majority being developed from soybean (Larkin, Ramage & Scurlock, 2004; Demirbas, 2008). Instead of going to the fuel station, you can plug your vehicle into a charging station. Ethanol burns more cleanly in air than petroleum, producing less carbon (soot) and carbon monoxide. Perhaps the answer lies somewhere in-between, weaning people off of oil and heading to solar, wind, and other alternative sources where it does make financial sense to do so right now. Increased energy security. Plant-based fuels come from renewable sources, can be grown anywhere and have lower carbon emissions as . 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. An important advantage of the alternative engine is the use of liquid fuels of great calorific value. It is conceivable that biofuels will become a selective alternative to fossil fuels as a source for transportation fuels but not a complete substitute. In America, we're embracing renewables at a remarkable rate, with clean energy now outpacing . Send me the latest news in (check all that apply): Benefits of alternative fuels and fuel-flexibility. Reduce Toxicity in the Atmosphere Both kinds of fuel - biofuel and fossil fuels - produce carbon as an end product when the fuel is burnt. The disadvantages of natural gas as an energy source include: Natural gas is still a fossil fuel. 2. Propane engines grant a set of environmental benefits to users. Alcohol has low sulphur content in fuel. The advantages of ethanol use are: The fuel can utilise existing distribution outlets. Businesses who wish to switch their vehicles to RNG often opt to construct a fueling facility on their own premises. Biodiesel also thickens greatly in cold temperatures and burns poorly under such conditions. Global warming: Burning of fossil fuels is believed to be one of . 1 Fossil fuels are cheap, reliable, and widely available. Ethanol blending is extremely common. As, electricity is costly. Compared to traditional fuels for transportation, this can take billions of carbon out of the air we all breathe. Coal mining occurs underground or through strip mining efforts. Higher densities of ethanol fuel and air can be combusted in an engine compared to petroleum due to ethanols constricted boiling point range and higher latent heat of vaporization (Brown, 2003; Demirbas, 2008). Natural gas use in motor vehicles has increased over the last six years. Renewable energy technologies could produce many jobs in the future. 2. Renewable diesel can be used as drop-in replacements. In the past, coal became an alternative to wood fuel, while oil was replaced by petroleum. Agricultural machinery, mining equipment, ships, locomotives, and other vehicles can all potentially benefit from using alternative fuels. At present, commercial biofuel production is a controversial issue that is still relatively new. 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. Alternative fuels are considered to have a less adverse effect on the environment, and are stated to be a solution to the problems created by fossil fuels (SEP, 2009). In 2020, there were 157 facilities producing RNG. It then compresses into high-pressure storage vessels. Ethanolbasically, alcoholcan also be used in traditional SI (spark ignition) vehicles when it is blended with gasoline. 2) Zero Carbon Emissions. Wind power gives us energy without contaminating the environment at all. What are the economic pros and cons of biofuels? By the end of 2021, this number had grown to 230. Other advantages associated with HEVs can sometimes even include higher resale value. The development of better second and third generation biofuels would be more effective as they potentially use less land and have a greater chance of being a viable alternative for fossil fuels. More about Kevin and links to his professional work can be found at www.kemibe.com. Never miss the latest and stay ahead. Economy. For instance, the placement of turbines for wind energy can make construction costs 50% more expensive compared to nuclear energy. The biogas is refined into RNG, and then used to fuel their garbage collection fleet. In summary, propane is a great option for clean, environmentally-friendly vehicles. So do solar panels. These trains need engineers and other workers to remain functional. Registered office: Creative Tower, Fujairah, PO Box 4422, UAE. Similarly, vehicles and other machines can be built to extract energy from the combustion of the hydrocarbons in fossil fuels, as is traditionally the case, or they can be made to rely on other chemicals and inputs. Alternative fuels are meant to be alternative collections of chemicals or other sources of energy. It does not affect the ozone layer and, as stated, has very low global warming potential. Alternative fuels can create jobs, but only for a small minority of workers. Fixed costs tend to include land charges, wages for labourers, insurance and depreciation of assets such as equipment and buildings (Vadas, Barnett & Undersander, 2008). Hydrogen: This promising but extremely volatile fuel has the advantage of being ubiquitous, and its only waste product is water vapor. 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. It may be derived by fermenting carbohydrates obtained from natural sugars, starches or cellulosic biomass in plants including sugar cane, corn or straw (Gupta & Demirbas, 2010; Larkin, Ramage & Scurlock, 2004). 8. As it takes a long period to get a return on the investment which does not justify the initial investment. Alternative fuels are a sustainable form of energy, are fuels that have not derived from petroleum and can include alcohols, biofuels, hydrogen, natural gas and propane (Saddleback Educational Publishing, 2009). Natural gas has been used for decades in non-transportation applications. So, the production of hydrogen gas is expensive. 3) Cleaner Air and Water. It's environmentally friendly. In some cases, for example, converting a diesel truck to run on CNG can be more cost effective in the long run than investing in diesel exhaust emissions control equipment. There are several advantages concerning the use of methanol and ethanol as alternative fuels. Here are some of the disadvantages: Renewable energy infrastructure will need to be produced from scratch, which is expensive and time-consuming. To begin with, what is a fuel? One of the biggest disadvantages of renewable energy is that it is unreliable. How do you feel about the subject? Hydrogen cars also give the driver excellent mileage compared to regular gasoline cars. 100% Biodiesel is actually just as biodegradable as sugar and ten times less toxic when compared with table salt. Advantages of non-renewable energy are: The major benefits of nonrenewable energy are their abundance and low cost. Carbon dioxide in the atmosphere is re Lets look at the real advantages and disadvantages of switching to renewable energy sources. Renewable Energy Sources Will Not Run Out As it comes from the name, a renewable energy source is sustainable, meaning that it will not run out soon. The advantages and disadvantages of alternative fuels are debated in the editorial pages of major newspapers in the United States and worldwide every day. The advantages at a glance: Synthetic fuels emit significantly less particulate matter and CO2. The exhaust contains about 50 percent less nitrogen oxides. Advantages. This includes pipelines for transportation between natural gas-producing regions and population centers. There are disadvantages linked to the use of methanol and ethanol as alternative fuels. This makes installing propane fueling stations easy and cost-effective. Chemically, biopropane is nearly identical to propane obtained from fossil resources, so both fuels are interchangeable in many applications. Lower carbon emissions make them a safer alternative to preserve atmospheric quality and lower air pollution. Businesses who do choose to build a Compressed Natural Gas (CNG) fueling station on their premises have several options. Instead, nuclear power plants release clouds full of harmless water vapor, which is infinitely better for both humans and the environment. RNG can be fully interchangeable with traditional natural gas. Nonrenewable materials have a high energy content. Although there have been improvements made in the last decade, the manufacturing processes for alternative fuels does not have the same level of infrastructure as traditional fuels. Engine performance. Of these, the most commonly extracted and used one is Bioethanol or simply Ethanol and Biodiesel. She strongly believes in eco-friendly living and is vocal about renewable energy, environmental issues, water crisis, and sustainable living. A variety of organic materials feed the biogas-producing bacteria. If all of it was used in transportation applications, it would be enough to fuel about two thirds of all diesel vehicles in the country. Mostly, energy projects are situated in regional areas away from big cities, bringing benefits to these places as well. Although it doesnt happen immediately and there may be additional costs in the short-term, the long-term benefits may actually help a nation save money. There are no chemical processes taking place beyond the creation of a turbine that spins when the wind blows. It's less costly compared to other fossil fuel energy sources. This is also true of several newer biodiesel and synthetic . There are, in comparison, about 145,000 gasoline stations. 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. Winter power outages can be serious even if you live in a typically warm climate. Californias carbon reduction and air quality policies (i.e. U.S. Life Expectancy Fell With Covid Vax Rollout, NY Times Blames Why Does Trump Keep Promoting the Vaccine? It produces less emissions than gasoline (petrol). The systems needed to fuel a vehicle with RNG or with fossil natural gas are identical. People may not have the skills to create alternative fuels. In Table 4, it can be seen that current fuel yield for soybean biodiesel was between 225-350 L/hectare and that the necessary area of land to meet even 50% of US transport fuel needs was over 180% of US cropland. In 2021, businesses registered around 6,500 natural gas vehicles. When refueling vehicle, the high-pressure vessel discharges rapidly into the vehicles tank. Free resources to assist you with your university studies! With that being said, natural gas vehicles are the least disruptive alternative power technology available today. and the polluting and limited nature of fossil fuels. 3. 10. For now, they all suffer from practical constraints on their use. Hydro generators need rain to fill the dams for the supply of flowing water. They can be used anywhere that there is generous source of sunlight. Thats up from 92% in 2020. It allows for energy independence to be achieved. Certain businesses have the option to integrate the production and use of fuel as part of their normal operations. Ethanol is still far from being economically competitive when compared to fuels derived from fossil fuels (Larkin, Ramage & Scurlock, 2004; Howard & Olszack, 2004). There are many advantages of using fossil fuels as opposed to renewable energies. Although switching to renewable energy sources completely, might not be possible yet. 12. LNG stations typically serve long-haul trucking applications. We're here to answer any questions you have about our services. Biofuels are effective on a small scale basis, but not on a large scale. Some even argue that coal gasification is an alternative to petroleum. Globally, approximately 1.5 million tonnes of biodiesel per year is produced (Larkin, Ramage & Scurlock, 2004). Unlike methane, the primary constituent of natural gas, propane is not a GHG. Whereas, wind energy and biofuel plants can be big visual pollutants, spoiling the beauty of the landscape. 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? Time-fill stations are best suited for heavy vehicles with large tanks that refuel nightly at a central location. Once that structure or foundation is in place, however, the contribution to atmospheric pollution stops. Alternative fuels present a variety of other advantages. Here are some time tips in case your family ever finds itself without power in the middle of winter: Power outages are always inconvenient. 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). 4) A Cheaper Form of Electricity. Hydrogen: This promising but extremely volatile fuel has the advantage of being ubiquitous, and its only waste product is water vapor. Aytek Yuksel is the Content Marketing Leader for Cummins Inc., with a focus on Power Systems markets. This solution to solar energy can be quite expensive. The transition from an oil-based fuel society to an alternative-based fuel society could take more than 100 years because thats how much time weve had to build-up our current expectations. Using ethanol over fossil derived fuels can result in a reduction of CO2 up to 75 percent (Howard & Olszack, 2004). The disadvantages of hydrogen as an alternative fuel are, Hydrogen is expensive. Wind turbines need wind that turns their blades. The use of ethanol as opposed to . This is a lot of RNG, yet still just a fraction. Unlike petroleum, ethanol is a renewable resource. Grown, Produced and Distributed Locally: Fossil fuels are limited and may not be able to fulfill our demand for coal, oil and natural gas after a certain period. Time-fill stations offer more flexibility and efficiency for fleet managers who can make the most of off-peak electricity rates at night. This allowed to save fuel needed for the war effort. Cummins, a global power technology leader, is a corporation of complementary business segments that design, manufacture, distribute and service a broad portfolio of power solutions. Fossil fuels are cheap, reliable, and widely available. Currently, nearly 45 percent of Australias total energy consumption is accounted for by coal, with oil providing approximately 35 percent, natural gas supplying around 15 percent and green power providing just over 5 percent (Hillstrom & Hillstrom, 2003). Nina Howell is a Rewenable Energy researcher and consultant based out of Houston, Texas Area. It may be possible to increase the production of RNG in the United Statesand in other countriesby orders of magnitude. It is usually obtained by refining crude oil or wet natural gas. It has been used for decades in a variety of applications, including as a cooking and heating fuel, as a refrigerant fluid in air conditioning systems and as a propellant in aerosol sprays. So, the sources of energy that suit to be named alternative are solar, wind, hydroelectric, marine, and geothermal energy. Ethanol: This alcohol can be added to regular gasoline in amounts ranging from 10 percent to 83 percent or so. This has contributed to global warming. Environmental degradation is an issue related to ethanol production from crops, which leads to the concern of whether biofuel generation is indeed sustainable for certain crops (Vadas, Barnett & Undersander, 2008). 2. With HEVs becoming increasingly popular, and due to its advantageous technology, HEVs can often have higher resale value. It creates a new employment section. Methane, the main constituent of natural gas, can also be obtained in a renewable way by fermenting organic waste. Fossil fuels are unequally distributed and make the global economy dependent on a few exporting countries. The energy created from alternative fuels does not require a lifestyle change. A study by the Gas Technology Institute found that school buses running on propane can generate 21% lower well-to-wheels GHG emissions compared to buses running on gasoline. Wet natural gas is natural gas that contains an excessive proportion of propane, butane and other non-methane hydrocarbon molecules. Biodiesel can achieve an energy ratio as low as three to one (Larkin, Ramage & Scurlock, 2004). Never miss the latest and stay ahead. How much renewable natural gas is out there? Of these, 64% of all on-road fuel used in these vehicles in 2021 was renewable natural gas (RNG), according to industry trade group, NGV Americas. The use and manufacturing of alternative fuels in Australia will then be assessed. 1) A Fuel Supply That Never Runs Out. The clearest fact is that maintaining a balance between lots of different sources of power is the ultimate solution to solving all our energy problems. The main difference between fossil derived fuels and alternative fuels is the oxygen content, with alternative fuels having 10-45 wt% oxygen compared to fossil fuels which contain almost none (Gupta & Demirbas, 2010). It is being used increasingly as a fuel source for fuel-cell vehicles. Propane: This small, unbranched hydrocarbon, which exists in liquid form at room temperature, has been used for decades.
