The recent breathtaking spike in oil prices has finally awakened professionals in the energy field to the very real need for alternatives. As a result, we are seeing liquid fuels developed from plant materials entering the market. Sugar components of various plant materials if fermented will yield an alcohol called bioethanol. Even cellulosic biomass (trees and grasses, for instance) can be used to produce this kind of biofuel. Ethanol, widely used in Brazil as well as in the United States, can, actually, be used in a pure form; however, it is used more as an additive to boost octane in addition to reducing emissions.

Biodiesel, on the other hand, is made from oils—vegetable or animal. Very often, greases are recycled and used for biodiesel. Like ethanol, it can be used in its pure form for diesel engines but is more often treated as an additive. This is the most common biofuel in Europe. The process for producing it from fats and oils is called transesterification.

In 2008, 1.8% of the world’s transport fuel was biofuel. Investment in the production of this new approach to fueling transportation vehicles for the world is expanding rapidly. It was billion in 2007. The liquid biofuels are the most popular ones for these purposes because they can be pumped, and they can directly replace gasoline. Not only do internal combustion engines run cleaner on biofuels, but pollution is also minimized. Biofuels are generally classified as first generation, second generation, and third generation.

First generation biofuels are made from sugar, starch, vegetable oil, or animal fats. Grains such as wheat are fermented into bioethanol; sunflower seeds are pressed to yield vegetable oil for biodiesel. The most common first generation biofuels:

- Bioalcohols

- Biodiesel

- Vegetable Oil

- Bioethers

- Biogas

- Syngas

- Solid biofuels

Second generation biofuels are made from non-food crops such as waste biomass, stalks of wheat, corn, wood, and certain grasses. To avoid the political issues that have arisen from the use of food that is needed for humans and animals to produce fuel, the pressure is on to develop more of these sources. Some of the second-generation biofuels under development:

- Biohydrogen

- Biomethanol

- DMF

- Vio-DME

- Fischer-Tropsch Diesel

- Biohydrogen Diesel

- Mixed Alcohols

- Wood Diesel

Third-generation biofuels are made primarily from algae, which can produce up to 30 times more energy per acre than land crops such as soybeans. However, they have not yet been produced commercially. These are biodegradable and will not harm the environment if they happen to be spilled. Algae can be grown agriculturally. It’s estimated that 15,000 square miles of algae would meet all the needs for petroleum fuel in the United States.

- Agricultural Algae

- Ethanol from Living Algae

- Helioculture (collection of carbon dioxide from the air using solar power)

For the non-scientist, this seems somewhat complicated, but more and more professionals in the appropriate fields are switching to this quickly-emerging industry, and we can hope that many of the problems the world faces now in obtaining energy without jeopardizing our environments will see solutions in the coming years.

Oil prices have always been a concern. Recent events, along with increased awareness of the environment, have shown us the need for the creation of alternative means of energy.

Many different options have been proposed. Nuclear power is possible but comes with obvious safety concerns. Solar and wind look like viable options, but don’t seem to be getting large amounts of support. Another option is biofuel, which involves using the energy of organic materials to replace the function 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 blend with regular fuel.

Another kind of biofuel is biodiesel, which is made from either vegetable oils or animal oils. It’s actually possible with today’s technology to take the fat that comes from the grills at McDonalds and recycle this into usable fuel! As with ethanol, it can be used purely on its own but is commonly just a supplement to be added with other fuel. It’s currently the most common biofuel in Europe. The process of turning animal and vegetable oils into usable fuel is known as transesterification.

1.8% of the world’s transport fuel was biofuel in 2008. This figure seems small, but investment in these technologies is continually increasing, and will inevitably create new technological breakthroughs and a rise in popularity. Biofuels come in many different forms, and are commonly categorized into first, second and third generation.

First generation fuels are made from food crops such as sugar, starch and animal or oil fats. Grains can be made into bioethanol, and sunflower seeds into vegetable oil and then biodiesel. These are the most common first generation biofuels: Biodiesel, bioalcohols, vegetable oil, bioethers, solid biofuels, Syngas and biogas.

From non-food crops like waste, stalks of wheat and corn we get the second generation of biofuels. Since first generation biofuels are made from edible sources, the hunt is on to create more second-generation technology that can avoid a food shortage that may occur. They include biohydrogen, biomethanol, mixed alcohols and wood diesel.

Third-generation biofuels are the most complex, and come usually from algae, which produces a large amount of energy. While the advantages of third generation fuels would be great, since it’s virtually impossible for them to cause environmental damage, the technology has so far not been sufficiently developed to allow these biofuels to be produced commercially. It’s been put forth that 15,000 square miles of algae could supply all the petroleum fuel required by the United States.

These new technological developments show just how exciting the field of biofuel is, and the great benefits it can provide to the environment. The current environmental problems and massive fuel prices could perhaps be fixed forever with the further development of second and third generation fuels. Who knows what will be powering us fifty years from now?

Biofuels Market in China 2010

Biofuels has huge growth potential in China as domestic and foreign biofuel producers have either started their production facilities or are working on the feasibility plan of establishing a facility. Recently, domestic and foreign players have formed joint ventures to develop second generation biofuels. The government is taking initiatives by investing in the development of marginal land on which non food crops are grown for the production of biofuels. Development of second generation biofuels along with government’s support will drive the biofuels market in China. ( http://www.bharatbook.com/detail.asp?id=154292&rt=Biofuels-Market-in-China-2010.html )

The report begins with an introduction of biofuels market indicating different types of biofuels and its respective feedstocks. This is followed by an overview of the bioethanol and biodiesel market including its production capacity and different available feedstocks used for the same. It further talks about the development of second generation biofuels i.e. cellulosic ethanol.

An analysis of drivers explain factors contributing to the growth of biofuels market including depleting and dependency on oil reserves, rising automotive sector, degradation of environment, international partnerships and social impact. The key challenges identified include scarcity of land and water and food security. Government initiatives have been discussed indicating the subsidies given to develop the market.

Competition section provides brief profiles of major domestic and foreign players in the market. The section contains a snapshot of their corporation, financial performance and business highlights, providing an insight into the existing competitive scenario.
