Using biofuels based on coconuts, soybeans or sugarcane for energy generation has been around for some time.
Using biofuels based on coconuts, soybeans or sugarcane for energy generation has been around for some time. In the late 1990s, several applications of coconut oil caught on in the Pacific. Major problems with using copra oil in engines are clogging filters and the oil turning solid at 24ºC. A heat exchanger and using filtered clean copra oil can solve these problems. The motor has to be equipped with a diesel fuel system to start the engine and a coconut oil fuel system to run it. A controlled device heats the coconut oil and, once liquid, automatically switches from diesel to coconut oil. The Secretariat of the Pacific Community and the international centre for cooperation on development-oriented agricultural research (CIRAD) have established electricity generators on Vanuabalavu and Taveuni islands, Fiji, supplying electricity to 198 and 60 households, respectively, and a small oil extracting plant that supplies half of its oil yield for electricity generation. In Vanuatu s capital, Port Vila, a car company runs its vehicles on a blend of coconut oil and diesel in an attempt to convince motorists to fit their engines with a 75 heat exchanger and use a coconut/ diesel blend. This blend, named island fuel , contains 60% clean copra oil and sells in Port Vila at 12 Vatu or 0.09/litre less than diesel. In 2002, more than 100 local buses were driving on this island fuel . A group of coconut producers from Lorevulko and Port Olry on the east coast of Espiritu Santo Island have formed Lory Coop to take up the challenge and are using copra oil for rural electrification, including for running a copra oil mill, cooling facilities and cassava and taro milling. POPACA, a rural development project funded by the European Commission and the French Ministry of Foreign Affairs, will supply the generator. In Vanuatu s agricultural economy coconut is the most important commodity, and low and fluctuating world market prices make it attractive to sell it locally with an added value for the production of affordable electricity. In Port Olry, the cost of diesel is 1/litre, whereas copra oil processed locally costs only 0.43/litre. François Japiot Projet POPACA Port Vila, Vanuatu Fax: +678 28 045 Email: email@example.com
