Algae and jatropha, two types of promising and unconventional biomass, are investigated in this study for large-scale production of biodiesel. The aim is to evaluate the potential advantages and the magnitude of closeness of life cycle balances between these two biodiesel pathways compared to fossil diesel, by taking into account possible uncertainties. The geographical location of this study is India with a prospect of utilizing available wastelands in southern regions. The results indicate that the environmental performance of algal biodiesel is comparable to that of jatropha biodiesel. Both show significant GHG emission and fossil energy depletion reductions which are in the range of 36-40 and 10-25% respectively compared to fossil diesel in the studied geographic context.
本研究以藻类和麻疯树两种有前途和非传统的生物质为对象，探讨了大规模生产生物柴油的问题。本研究的目的是通过考虑可能的不确定性，评估与化石柴油相比，这两种生物柴油途径在生命周期平衡方面的潜在优势和接近程度。本研究的地理位置是印度，预计将利用南部地区现有的荒地。研究结果表明，藻类生物柴油的环境性能与麻疯树生物柴油相当。与研究区域内的化石柴油相比，两者的温室气体排放和化石能源消耗均有显著减少，分别在 36-40%和 10-25%的范围内。
