With worldwide climate change and global temperatures rapidly climbing, people are turning to cleaner sources of energy. Biodiesel is a promising alternative fuel that can make the Earth a healthier place to live in. Today, there is increasing expansion in the production, distribution and use of this clean and renewable energy supply.
Biodiesel is made from a process called transesterification, where the fats and oils in animals and plants are processed into the substances that compose the fuel. As early as 1853, scientists J. Patrick and E. Duffy had already conducted a kind of transesterification of vegetable oil.
In 1900, Rudolf Diesel, the inventor of the diesel engine, demonstrated a diesel engine that ran on peanut oil at the World Fair in Paris. However, this peanut oil fuel is not considered biodiesel because it didn't go through the transesterification process.
Interest in the use of vegetable oils as fuels remained through the 1920s and 1930s. Different countries, such as France, the United Kingdom, Japan, and China tested and experimented with these oils during; however, they encountered some problems because of the viscosity of the vegetable oils, which led to engine deposits.
In 1931, the first biodiesel production was done by G. Chavanne of Belgium. Since then, research and experiments have been counducted to improve the manufacture and use of biodiesel. In the 1990s, European countries began installing biodiesel power plants. By 1998, 21 countries began producing commercial biodiesel products. Today, manufacturers can use several sources to make biodiesel, like animal fats and plant oils from palm, sunflower, peanut, soybean or canola.
In Australia, all metropolitan trains and almost all buses in Adelaide run on 5% biodiesel mixed with petroleum. The South Australian Government plans to move up to 20% biodiesel soon. In Canada, the government has set a goal of producing 500 million liters of the fuel by 2010. In Finland, a local oil company plans to build a production plant with a capacity of 170,000 tons per year.
In 2005, a power plant capable of producing 50 million liters per year opened in Scotland. In Brazil, three commercial biodiesel factories have been producing 45.6 million liters of the fuel per year. In India, the government is encouraging the cultivation of Jatropha plants, the oil of which is used for railway engines. Malaysia has long been developing palm biodiesel as a diesel substitute.
Farmers in the United States use the fuel in tractors and other equipment to raise public awareness. Aside from these countries, Belgium, Costa Rica, Thailand, Singapore, the Czech Republic, Norway and others have also already taken steps to increase their biodiesel production.
National governments around the world are making policies to increase the biodiesel blends that they use to fight global warming. By improving fuel technology, establishing larger biodiesel networks, raising people's awareness and increasing biodiesel use, the Earth may see a better future through this clean and green fuel.
