碩士 / 國立交通大學 / 高階主管管理碩士學程 / 98 / With noticeable oil price hike and increasing protective
consciousness of environment, it becomes the prime goal for all countries to develop new and clean alternative energy. Biodiesel has received much attention in recent years, since it is biodegradable, contains no sulfur and benzene compounds, and releases less pollutant substances after burning. Biodiesel is an alternative energy that is both environmental friendly and has sustainable operation achievability. Currently, most of the biodiesel is produced from vegetable oils of terraneous oil-crops, such as soybean, rape seed and palm oils. The production of biodiesel from microalgae is a newly emerging field due to it’s larger biomass, larger growth rate compared to those of oil-crops. However, it was rare investigated for the
economic assessment of microalgal biodiesel in Taiwan. Therefore, the main purpose of this article was to study the cost of biodiesel from microalgae oil based on domestic conditions and the effects of the relative economic importance of each variable with sensitivity analyses, and then the suggests for future development of microalgae derived biodiesel were proposed.
There were three production procedures and two scenarios for
microalgal biodiesel being set in this article. By the analysis results, it was found that the cost and IRR(Internal Rate of Return) of algae oil production for open system, close system and fermentation were NT$22.7/kg and 8.91%, NT$27.94/kg and 5.33%, and NT$24.83/kg and 5.44%, respectively. Moreover, from ‘sensitivity analyses’ it is clear that the three most important factors for facilitation of microalgal biodiesel production systems are ： (1)The reduction of cultivation systems construction costs ； (2)The increase of biomass/algae oil yield ；
(3)Extractable HVP value or oil commodity price. Those analyses obtained that the cost of microalgal oil remain in an higher stage compare with crude oil, but they are now approaching profitability compare with those of terraneous oil. They may be a raw material for biodiesel production with decreasing cost in the future. Finally, the suggestions of business management and execution strategy for biodiesel production by microalgae, and the future researches of microalgae were proposed. Those could be a reference for people who are interesting in the development of microalgal biodiesel.
