What is bioenergy?
Bioenergy is renewable energy created accessible from materials derived from biological sources. Biomass is any organic material that has hold on daylight within the form of chemical energy. As a fuel it could contains straw, wood, sugarcane, wood waste, manure, and plenty of alternative byproducts from a range of agricultural processes.
In its narrow meaning, it's an equivalent word to biofuel that is fuel derived from biological sources. The broader sense of bioenergy consist of biomass, the biological material used as a biofuel, as well as scientific, economic, social, and technical fields related to using biological sources for energy.
Types of biofuels
Solid biofuels:
Solid biofuels include manure, wood or charcoal burned as fuel as well as more recent innovations like high-density clean burning pellets. Solid biomass can be burned to produce electricity or heat either as part of a co-firing power plant or by itself. The most important advantages of biomass fuel is that it is most of the time got by waste-product of other processes, product or residue, such as farming, animal husbandry and forestry. In theory this suggests there's no competition between food production and fuel, although this can be not continually the case.
Liquid biofuels:
Disparate other renewable sources of energy, biomass can be converted directly into biofuels for our transportation needs (airplanes, cars, buses, trucks, and trains). The most important types of biofuels are two, which is biodiesel and ethanol.
Corn can be harvested to produce ethanol.
Biodiesel:
Biodiesel is made by integrating vegetable fat, oil animal, or recycled cooking greases with alcohol (usually metha...

In the process of extracting energy from the sun, algae may be the best organic intermediary, since they can double their size in a day, making them among the most efficient organisms at converting light energy into biomass. Oil is then extracted from the algae, creating a product almost chemically indistinguishable from light, sweet crude oil, except that it is green in color. From the thousands of algae species, those high in starch are best, since they need a good supply of carbon dioxide to grow at an acceptable clip, and they can feed on nutrients in sewage, raising the appealing prospect of producing fuel while treating sewage. They are aquatic, but can grow isalty or brackish water so they don't have to compete for the land and water needed to grow food crops.
Biodiesel is produced by subjecting the triglycerides found in vegetables oils and fats to transesterification, which is the exchanging of the alkoxy group of an ester compound by another alcohol. This creates an ox...
As stated earlier, the burning of fossil fuels to produce energy is one of the largest contributors to global warming. This non-environmentally friendly energy source has to be replaced in order to keep the world going. There is a type of energy source that seems easy to create and doesn’t require radical changes: Biofuels. Biofuels are a greener version of diesel and oil. They are any solid, liquid, or gas fuels produced from organic matter; the range of organic materials used for biofuel production includes plants such as corn, sugar cane, soy, and wheat; vegetable oils and animal fats; ...
Technically, the method is not thought of as a biofuel because it was not produced from a crop. Ethylene is used and it is produced through catalytic cracking. This is an addition reaction that is exothermic and is shown through the equation: CH2=CH2(g) + H2O(g) → CH3CH2OH(l) ΔH = - 45kj
The energy that we use presently has raised numerous questions, whether or not it would bring us danger. Thus, scientists tried to find new types of energy that we can use in the future that would not increase the chances of having global warming for other environmental crises. Renewable energy has been examined and tested for many years; and, it [has been proven that it is much better than fossil fuels. Types of renewable or alternative energy include wind power, solar power, and geothermal energy (About, Alternative Energy Resources 2007). Particularly, biomass, “in the energy production industry, refers to living and recently dead biological material which can be used as fuel or for industrial production. Most commonly, biomass refers to plant matter grown for use as biofuel, but it also includes plant or animal matter used for pr...
Introduction:The idea of biofuels is a old concept, reaching as far as the ending of the 19th century. Solid in its idea but flawed in its presentation. Biofuels are a alternative energy to fossil fuels that are made from natural methods such as plants and crops and are key in solving the apparent flaws of fossil fuels. While fossil fuels have been in use for over a century, Biofuels have now risen to the popularity and been exposed to the press. At one point of time biofuel were being considered by some of the most brilliant minds ever in human history such as Henry Ford and Rudolph Diesel who believed that biofuels had the potential to be the new evolution s on only to reappear a century later. Now the world faces the struggles of global warming and the depletion of fossil fuels slowly dimming by day. Throughout the last century biofuels have proven to have a place in our society as a new alternative fuel source. Specializing in Being Natural and healthier than fossil fuels, biofuels have had a rough beginning against its competitor due to key situations such as pricing, Side effects, to fuel power. However the idea was passed on a to the later generations, and continued to pasand prolong usage. However through the last decade they have been highly advertised by politicians and Government officials claiming it to be the future of a powerful working society, and to help in making a new energy free world. Through belief Some even claiming that “By 2050, a new generation of sustainable biofuels could provide over a quarter of the world’s total transport fuel, according to a recent report by the International Energy Agency” (last name). With such improvement biofuels should be the obvious answer to providing a better future to th...
In the world of global warming, all kinds of pollution and fuel shortages going on, renewable and clean/ green energy is increasingly the ideal solution of energy related problems we have to solve one way or another. Biofuel is one of the mainstream and highly supported solutions nowadays, an idea to make renewable fuel by living organisms such as fiber, corn, vegetable oil or sugar cane. Unlike nonrenewable fossil fuels over extracted by people causing various environmental problems like generating a considerable amount greenhouse gas, current technology already lets renewable fuel like biofuels to shrink a certain amount of greenhouse gas production, making it a more ‘clean’ source of energy.
The continuous depletion of fossil fuel resources and their increased demand has changed the outlook from ancient resources of fuel to new resources especially biomasses of plant origin. Plant biomass is a promising raw material for fuel generation to sustain fuel requirements in the modern age. Basically biofuel these days can be divided into first generation and second generation depending upon the type of biomass used. Biofuel derived from sugars, oils, cereals, sugarcane and starch are categorised in first generation fuel while use of lignocellulosic biomass like soft and hardwood, agricultural wastes, straw and corn stover provides second generation fuels [1].
Nowadays, people around the world are demanding for more sustainable energy source other conventional fuels such as coal, natural gas and fossil fuel for their daily activities. However, conventional fuels are categorized into a non-renewable energy source. Thus, to overcome this problem, an alternative fuel called as biofuel is used to substitute the conventional fuels. Moreover, biofuel can grow in interest in many developing countries by using “modern” use of biomass to produce the clean liquid fuels. The uses of biomass as a biofuel feedstock may offer new employment prospects for people that stay in that region. The biomass that commonly been used in biofuel is called as algae biofuel or oilgae, in which the oil that does not consist of toxic or sulfur contents in it (Demirbas and Fatih Demirbas, 2011).
Biodiesel is a clean burning renewable fuel made by various mix of agricultural oils, recycled cooking oil and animal fats. It is intended to be used as a substitute for diesel fuel, or can be blended with diesel fuel in any proportion. Biodiesel can be used in almost any diesel engine with slight alteration and no damage to the engine. As it has lower toxicity and safer to handle compared to diesel fuel, it constructs green jobs and improving our environment.
Biogas – a term that has been synonymous to the rural culture, a viable alternate to the rapidly depleting conventional sources, a resource whose production is cheaper, and almost cent percent of the raw materials used to produce it get utilised. Owing to the tremendous rise in the fuel consumption, we need to search for substitutes – one that can replace (the already not-so-left resources), revive (a less polluting option) and replenish (the present state of livelihood).
...ch is used to replace natural gas. He also stated that, among the equipment used to burn the biofuel, the suspension burner have the ability to exceed 99% efficiency and whole-tree burner can reduce the cost of harvesting and handling woody fuels by about 35% (Brown, 2003). Moreover, the usage of bio-energy in long term is to provide a degree of ecological balance and climate change, avoid acid rain, reduce soil erosion and minimize water pollution (Gevorkian, 2007). Therefore, biomass is environmental friendly like solar energy. Based on the research that has been carried out regarding the synthesis of gas from biomass, the gas gasifies in the internal combustion engine. The relative energy density of synthesis gas is higher than the fossil fuel under certain conditions. In addition, the relative flame speed of synthesis gas can reduce the time for spark ignition.
Coal and crude oil are non-renewable resources. They take an extreme amount of time to form and due to that, they cannot be replaced once they have all been used up. However, when it comes to the biofuels, they are produced from plant material and are renewable. There are two types of biofuels: Biodiesel, which is made from rapeseed oil and other plant oils and is used in diesel-powered vehicles without needing any modifications to the engine, and Bioethanol, which is a liquid fuel that burns quite well and is made by fermenting sugars from sugar cane, wheat and other plants. In this essay, whether or not biofuels are becoming an increasingly important alternative to traditional forms of energy under environmental and economic benefits and
Even though production of biofuels, such as ethanol and biodiesel, is rapidly increasing, their contribution to total fuel consumption will remain limited. Biofuels are sources of energy produced directly or indirectly from organic material including animal waste and plant material. In order to be considered a biofuel, at least 80% of the fuel must be made from renewable materials. There are 3 main types of biofuels: ethanol, biodiesel and biojet fuel. Biofuels are considered to be renewable since they can be replaced as quickly as they are used however biofuels biofuel production requires the use of fossil fuels in the form of fertilizers, agrochemicals,
Biogas can be used as vehicle fuel when it has been cleaned. The biogas cleaning consists of water (H2o) and hydrogen sulphide (H2S) that lead to separation of carbon dioxide from normal biogas (60 % Methane and 40% Carbon dioxide) content (Petersson & Wellinger, 2009). Biogas production from energy crops like maize, ley and sugar beet is the efficient resource compare with bioethanol fuel because it provides high energy yield (Börjesson, & Mattiasson, 2008).
Biofuels were the first liquid fuel, which include oils, animal fats, and ethanol from crops (Kovarik). They use alternative sources of materials to create fuels, which can be a key feature for our future. Our economy uses some of the dirtiest and most harmful materials to create our fuels and everyday uses, which is slowly hurting our environment. The use of biofuels can save our money spendings, and have more of what we need to survive. People say that biofuels are not healthy for our environment, but in reality they are stronger and more efficient. Although many believe that biofuels are an unnecessary fuel source, biofuels are important for our environment; therefore, biofuels must be used as our alternative source of fuel, and
