Global Pulse: Biofuel – Another Flawed Policy?

See linktv.org (November 1, 2007) President Bush promised to expand American biofuel production, but the result has been worse than nothing. Corn is a poor source for energy, but growing it and other staples as fuel has caused food prices worldwide to explode – even as the scarcity of flex-fuel vehicles means no significant increase in US biofuel use. Now the UN is worried about rising food costs, while environmentalists see entire regions torn up to grow fuel crops. The great ethanol boom of 2007 goes bust, this week on Global Pulse.

An Introduction to Biofuel

oil prices have always been a concern. Recent developments, combined with increased environmental awareness, we have shown the need for the creation of alternative energy. Many options have been proposed. Nuclear power is possible, but come with obvious safety problems. Solar and wind look like viable options, but do not seem to be getting lots of support. Another option is biofuels, which involves the use of energy from organic materials to replace the role of fossil fuels. Ethanol is perhaps the most widely used of these, especially in Brazil and the United States, and is used most commonly as a mixture with regular fuel. Another type of biofuel is biodiesel, which is made from vegetable oils or animal oils or. It is actually possible with current technology to take the fat from the grill at McDonalds and recycle it into usable fuel! As with ethanol, which can be used exclusively on their own but is only a supplement to be added to another fuel. It is currently the most common biofuel in Europe. The process of converting animal and vegetable oils into usable fuel is called transesterification. 1. 8% of transport fuel from biofuels in the world was in 2008. This figure seems small, but investment in these technologies is growing, and inevitably create new technological advances and increasing popularity. Biofuels come in many different ways, and are usually classified in the first generation, second and third. First-generation fuels are made from food crops such as sugar, starch and animal fat or oil. The grains can be made into bioethanol and sunflower seeds in vegetable oil and then biodiesel. These are the first generation biofuels more common: biodiesel, bioalcohols, vegetable oil, bioethers, solid biofuels, syngas and biogas. Of the non-food crops such as waste, wheat stalks and corn yields the second-generation biofuels. Since first-generation biofuels are made from food sources, hunting is to create a second generation technology that can prevent food shortages that may occur. Include biohydrogen biomethanol, mixed alcohols and wood diesel. Third-generation biofuels are the most complex, and are usually from algae, which produces a large amount of energy. While the benefits of third-generation fuels would be great, because it is virtually impossible to cause damage to the environment, technology has so far not been sufficiently developed to allow these biofuels that are commercially produced. It has been repeated, that 15,000 square miles of algae could supply all the fuel oil embargo imposed by the United States. These new technological developments show how exciting the field of biofuels is, and can provide great benefits to the environment. The existing environmental problems and massive fuel price arrangements might be forever fuel the further development of second and third. Who knows what we will feed fifty years from now?

Bio-fuel for cars

The present veh?culos & lt; p& gt; they face a challenge to happen of exhausting and polluting of renewable fuels highly f? ? siles to and the combustible ones like m?green s See-fuels that are less polluting and can be mixed with fuels f? ? siles or to be used separately. We are going to discuss on some of these see-fuels. & lt; /P& gt; 1. Ethanol: caña is known them comúnmente like grain alcohol produced from vegetal sources like ma?z or azúcar by fermentaci? ? n. The ethanol has a high número of octane that produces a high efficiency of the motors. At world-wide level the ethanol est?gaining vile popularity and many manufacturers of autom? ? est?n developing veh?culos Flexi-Fuel (FFV). The veh?culos Flexi-fuel that use a mixture of gasoline and ethanol in one proporci? ? n of ethanol are as high as 85% with the gasoline a 15%. These fresh fruits and vegetables have one opci? ? n of percentage vari? ? of ethanol and gasoline. Now compañ?as est?n investing in doing this like m?s efficient and less polluting fuels. Bioetanol is the carbon-neutral one and has one of the very low emissions of di? ? xido of carbon during the use of the fuel and también during producci? ? n. & lt; /P& gt; 2. GLP Car-gas: This f? is a sil fuel ? that are very low polluting agents like of di? ? xido of carbon and xidos ? ? of nitr? ? geno in comparaci? ? n with the gasoline and the diesel engine. Light modificaci? ? n in the ready motor of combusti? internal ? n har?a to use GLP like fuel. GLP has a special property to turn to l?quido to presi? atmosférica ? n and can properly be stored in l?quida form. & lt; /P& gt; 3. Compressed Natural gas: Like the GLP, the GNC f? is a sil fuel ? and has a very low level of di? ? xido of carbon of emissions in comparaci? ? n with the gasoline or the diesel engine. Like the GLP, the veh?culos must be put under one conversi? ? n before being ready to use GNC like fuel. The GNC cannot be stored in l?quida form and it is stored in the form of gas compressed in cylinders like the GLP. GNC has stop value of the octane, therefore it is the efficient fuel. & lt; /P& gt; 4. Biodiesel: Produced from vegetal sources like oilseed rape, the sunflower and the oil of soybean. Biodiesel is green and is neutral in carbon since xido of carbon has done it of the very low emissions of di? ? during the use and producci? ? n. biodiesel can replace gas? ? I read in many cases, but the manufacturers of veh?culos are cautious and recommend 5% to 30% of biodiesel mixed with gas? ? I read in principle to study the wearing down. The modern motors are able to use the 100% of see-fuel. & lt; /P& gt; 5. Fuel cells: Aún in phases of investigaci? ? n can be soluci? ? n of vanguard. Fuel batteries are electro-qu?micas devices of conversi? electroqu?micos ? n of energ?a that turn energ?a of reacci? ? n. The electricity can continuously be produced, as long as the reagents are provided. At the moment this tecnolog?a is very expensive and todav?a est?in investigaci? ? n. & lt; /P& gt; Another caracter?stica of the see-fuel in debate is the fact that aumentar?presi? ? n on producci? ? n of grain foods as some of these see-fuels are of vegetal origin. producci? ? n in mass or podr?a to give rise to one reducci? ? n of the surface available for producci? ? n of grains for alimentaci? ? n or habr?one deforestaci? massive ? n. Although ? exists an urgent necessity to pass of fuels f? siles to fuels m?s green también is a clear necessity to quantify the impact in producci? ? n of grain foods and deforestaci? ? n. & lt; /P& gt;

Biofuel, a Primer

& lt; p& gt; Copyright (c) 2009 Wes Fernley & lt; /p& gt; The recent spectacular rise of the price of petr? ? I read finally has waked up the professionals in the field of energ?a to the true necessity of alternatives. Like result, we are seeing developed l?quidos fuels from vegetal materials in the market. Azúcar component of materials of different plants, if fermented they characterized by a called alcohol bioetanol. Even the biomass celul? ? sica (?rboles and grass, for example) can be used to produce this type of biocombustible. The ethanol, very used in Brazil, as? like in the United States, can, in fact, be used in pure form, nevertheless, is used m?s like additive to increase octane, adem?s to reduce the emissions. & lt; /P& gt; biodiésel, however, makes with oil-vegetables or animal. Quite often, the fats recycled and are used for the biodiesel. Like the ethanol, that can be used in its pure form for the diesel engines, but is m?often treated s like an additive. This m? is the biocombustibles común in Europe. The process for producci? ? n coming from fats and oils is called transesterificaci? ? n. & lt; /P& gt; In 2008, 1. 8% of the fuel of transport of the world was of biocombustibles. inversi? ? n in producci? ? n of this new approach of supplying of means of transport for the world est?expanding r?pidamente. One went of $ 4 billions in 2007. The l?quidos biocombustibles are m?s popular for these aims, since they can be pumped, and can replace the gasoline directly. s? ? the motors of combusti? internal ? n not to work the cleaning one on the biocombustibles, but contaminaci? ? n is reduced to m?nimo también. The biocombustibles generally are classified like of first generaci? ? n, second generaci? ? n and third generaci? ? n. & lt; /P& gt; biocarburantes of first generaci? ? n est?n done of azúcar, almid? ? n, vegetal oil or animal fats. The grains as the wheat ferments itself in ethanol; sunflower seeds are pressed to produce vegetal oil for the biodiesel. The biocarburantes of first generaci? ? n m?s common: & lt; /p& gt; – bioalcoholes & lt; /p& gt; – The biodiesel & lt; /p& gt; – Vegetal Oil & lt; /p& gt; – Bioethers & lt; /p& gt; & lt; p & gt; – Biog?s & lt; /p& gt; – Syngas & lt; /p& gt; – Biocombustibles s? ? lidos & lt; /p& gt; The biocombustibles of second generaci? ? n make from nonnourishing cultures, like biomass residues, the stems of wheat, ma?z, wood, and certain grass. In order to avoid the pol?ticos problems that have arisen from utilizaci? ? n of the foods that is needed them human beings and animal to produce fuel, presi? ? n is for the development of several of these sources. Some of the biocarburantes of second generaci? ? n in phase of development: & lt; /p& gt; – Biohidr? ? geno & lt; /p& gt; – biometanol & lt; /p& gt; – DMF & lt; /p& gt; – See & lt; /p& gt; – Diesel Fischer-Tropsch & lt; /p& gt; – Diesel Biohidr? ? geno & lt; /p& gt; – Alcohol Mixture & lt; /p& gt; – Diesel Wood & lt; /p& gt; Third generaci? ? n the biocarburantes makes mainly of seaweed, that can produce up to 30 times m?s energ?a by hect?criminal who the Earth cultures like the soybean. Nevertheless, aún has not taken place commercially. These are biodegradable and not dañar?the environment if, by chance, it has been spilled. The seaweed can agr?colamente be worked. Esteem that 15,000 kil? ? squared meters of seaweed podr?a to satisfy all the needs with fuel of petr? ? I read in the United States. & lt; /P& gt; – Agr?cola Seaweed & lt; /p& gt; – Ethanol from seaweed that lives & lt; /p& gt; – Helioculture (recopilaci? ? n of di? ? xido of carbon of the air using energ?a to pave) & lt; /p& gt; For the noncient?ficos ones, this seems something complicated and professional, but every time m?s in the corresponding fields est?n changing r?pidamente to this emergent industry, and we hoped that perhaps many of the problems that the world now faces in obtenci? ? n of energ?a without putting in danger our environment to see solutions in pr? ? ximos años. & lt; br/& gt; & lt; /p& gt;

3rd Generation Biofuel Algae

As known as Oilgae as well, is being considered to be the third generation biofuel. Its production is low cost and high yield, almost 30 times more energy production per acre as compared to the land required by other conventional feedstock to produce biofuels. At present researches are being conducted by Alga culture (farming Algae) to produce different fuels to harvest for making vegetable oil, biodiesel, bioethanol, biomethanol, biobutanol and other biofuels and it seems if the methodology is sustainable than other available biofuels then using algae to produce bio diesel would be the only viable method to replace the need of gasoline used for automotive today.

Biofuels are considered to be the best way to reduce green house gas emissions and alternate to the pollutant fossil fuels. But recently, according to Nobel Laureate Paul Cortzen findings, some of the most commonly used biofuels Bioethanol from corn and bio diesel from rapeseed releases Nitrous Oxide (N2O) is contributing much more to the global warming than the fossil fuels are contributing right now. Processing of biofuel form algae has been tested that it captures large amounts of CO2 and N2O available in the atmosphere( 40% in a course of full day and 80% in sunny days) and an acre of algae can produce enough oil to make 5,000 gallons of biodiesel in a year.

According to my point of view biodiesel and bio ethanol from rapeseed and corn is not only adding to global warming but economically it cannot be sustainable because its one of the main sources of edible oil. Ethanol demand can threaten the food prices. A recent study conducted by Center for Agricultural and Rural Development at Iowa State University reveled that considering the high-price crude oil scenario, U. S. ethanol production could reach 30 billion gallons by 2016, consuming more than half of U. S. corn, wheat and other coarse grain production and triggering higher meat prices for consumers, reduced production across-the-board for all segments of the meat sector, and even greater reductions in grain and meat exports. Taking in review the sustainability and economic factor biofuel from Alga culture seems to be most promising fuel for future.
