Use Algae as Renewable Energy for Bioenergy Fuel Production

Bioenergy is biodegradable, less CO2 and NOx emissions. Continuous use of petroleum sourced fuels is now widely recognized as unsustainable because of depleting supplies and the contribution of these fuels to the accumulation of carbon dioxide in the environment. Renewable, carbon neutral, transport fuels are necessary for environmental and economic sustainability. Algae have emerged as one of the most promising sources for Bioenergy production. It can be inferred that algae grown in CO2-enriched air can be converted to oily substances. Such an approach can contribute to solve major problems of air pollution resulting from CO2 evolution and future crisis due to a shortage of energy sources. This study was undertaken to know the proper transesterification, amount of Bioenergy production (ester) and physical properties of Bioenergy. In this study we used common species Oedogonium and Spirogyra to compare the amount of Bioenergy production. Algal oil and Bioenergy (ester) production was higher in Oedogonium than Spirogyra sp. However, biomass (after oil extraction) was higher in Spirogyra than Oedogonium sp. Sediments (glycerine, water and pigments) was higher in Spirogyra than Oedogonium sp. There was no difference of pH between Spirogyra and Oedogonium sp. These results indicate that Bioenergy can be produced from both species and Oedogonium is better source than Spirogyra sp.
