  • Biofuel, based on fuel derived from organic biomass from recently living animals or plants or their byproducts, has transformed from a niche alternative to fossil fuels (e.g., gasoline, diesel) to become a booming industr
  • The term “biofuels” encompasses a wide range of fuels, including vegetable oils, animal fats, ethanol, biodiesel (any oil or fat that undergoes transesterification to more closely resemble mineral-based fuel), and synfuel (fuel made from gasified organic matter, then liquefied to form fuel). The main common trait of all these fuels is that they are derived from organic biomass, rather than minerals.

  • In the early days of motorized transport, fuels derived from plants lost out to fuels refined from crude oil
  • first-generation biofuels -- chiefly, ethanol made from corn or sugar cane, or biodiesel made from vegetable oil
  • The source plants absorb carbon dioxide from the air as they are growing, and consequently, the carbon dioxide that is released when biofuels are burned does not represent a net addition of that greenhouse gas to the atmosphere.

cost

shared by dpurdy on 03 Nov 11 - No Cached
  • The cost of producing ethanol varies with the cost of the feedstock used and the scale of production. Approximately 85 percent of ethanol production capacity in the United States relies on corn feedstock. The cost of producing ethanol from corn is estimated to be about $1.10 per gallon.
  • Because a gallon of ethanol contains less energy than a gallon of gasoline, the production cost of ethanol must be multiplied by a factor of 1.5 to make an energy-cost comparison with gasoline. This means that if ethanol costs $1.10 per gallon to produce, then the effective cost per gallon to equal the energy contained in a gallon of gasoline is $1.65. In contrast, the current wholesale price of gasoline is about 90 cents per gallon.
  • A major hurdle facing commercial biodiesel production is the cost of producing the fuel. Vegetable oil seed procurement, transport, storage and oil extraction accounts for at least 75 percent of the cost of producing biodiesel. The cost varies depending on the feedstock used. For example, based on the market price for industrial rapeseed grown in Washington and Idaho, the estimated cost of producing biodiesel is $2.56 per gallon of rapeseed methyl ester. Recent estimates put the cost of production in the range of $1.30 per gallon (using waste grease feedstock) to $2.00 or more per gallon using soybean oil.

  • Biofuels are liquid fuels which have been derived from other materials such as waste plant and animal matter. There are two main types of biofuels – bioethanol and biodiesel. Bioethanol is used as a replacement for gasoline and biodiesel is used as a replacement for diesel.

  • Biodiesel can result in significant reductions in a number of air pollutants. In general, reductions are greater as more biodiesel is used, depending on the type of biodiesel (soybean, rapeseed or animal fats) and on the conventional diesel used in the blend.

  • biofuel has been recently grown, rather than stored and processed over many years. Biofuel is made from what can be grown today whereas fossil fuel comes from biomatter grown millions of years ago – and is therefore not renewable
  • Biodiesel is a clean, renewable and domestically produced diesel fuel. Both biofuels and fossil fuels are of an organic nature (made from biological matter) but biofuel has been recently grown, rather than stored and processed over many years. Biofuel is made from what can be grown today whereas fossil fuel comes from biomatter grown millions of years ago – and is therefore not renewable . Biofuel is not a finite resource - we are only limited by what we can grow.

  • The main reaction for converting oil to biodiesel is called transesterification.
  • The transesterification process reacts an alcohol (like methanol) with the triglyceride oils contained in vegetable oils, animal fats, or recycled greases, forming fatty acid alkyl esters (biodiesel)

  • Even normal
  • gasoline vehicles can operate on a 10 percent ethanol blend with no problems. Diesel cars and trucks can run on biodiesel, though older models may need to have their fuel lines and gaskets replaced with modern synthetic materials, since biodiesel is a solvent
  • and use of biofuels to power aircraft is expected to increase substantially in the next decade. Because current biofuel production relies heavily on crops that also function as food or livestock feed, emphasis is on developing new sources that don't cause deforestation and compete with food production

  • Small engines, like those found in lawn mowers and chainsaws, can use ethanol blends up to 10 percent without problems. The barrier to using higher blends, up to 20 percent, has more to do with manufacturers' warranties than limitations of the technology

  • iofuels are potentially carbon-neutral, because although carbon dioxide is released when we burn them, carbon dioxide is taken in by the plants as they grow. However, energy is needed to grow the crops, harvest them, and to process the results into usable products - and most of this energy will be from fossil fuels for farm machinery and power stations.

  • Algae - that's pond scum - are microscopic water plants. They reproduce and photosynthesise fast, and the algae are then filtered out of the water and the lipids (oils) are used to make biodiesel.
  • It is claimed that growing plants to make biofuels will take in that carbon dioxide again. But biologists tell us that forests are not 'the lungs of the planet' after all - they give out as much CO2 as they absorb as the plants respire. It seems that it's plant plankton in the oceans that takes in most CO2 and gives out most oxygen.
  • It takes huge areas of land in order to grow crops for biofuels, although making biofuels from algae does not have this problem
  • Biofuel production is closer to being carbon-neutral than using fossil fuels.
  • Is it renewable? Biofuels are renewable, we can plant more of the crops or grow more of the algae.

    World biofuels production declined by 0.4% in 2012, the first decline since 2000. Increased output in South America and Asia Pacific was outweighed by declines in North America and Europe. Global ethanol output declined by 1.7%, the second straight annual decline. Biodiesel production grew by 2.7% and has doubled in the last five years and now makes up 31% of total biofuel supply.

  • Biofuels are made with biomass (biological material from living or recently living organisms) there are many kinds, for example biodiesel involves growing crops that contain large amounts of natural oil, these plants then go through a refining process and subsequently are mixed in with regular diesel to power cars. Bio petrol is made in a similar way; plants are refined to make a natural ethanol.

  • Bio fuels are a viable alternative to fossil fuels.
  • Some examples are that of biodiesel, which entails growing crops that contain high amounts of natural oil then through a process of hydrogenation or refining a more compatible bio diesel, substitute is created.
  • These are examples of first generation biofuels and due to their nature they may or may not be long-term economically or environmentally viable.
