Technical insights of microalgae derived bio-diesel on its performance and emission characteristics, techno-economics and practicability huddles

Due to the growing awareness of the depletion of fossil fuels, biodiesel production has attracted a lot of interest recently. Since microalgae grow quickly and produce more oil than traditional biodiesel feedstock, they are attractive candidates for biodiesel feedstock. The productivity and oil content of microalgae have been targeted for improvement. Microalgae biomass has gained interest based on the characteristics of microalgae and its ability to overcome the harsh environment as well as its high efficiency on photosynthesis. Knowingly, the microalgae oil qualifies as prospective feedstock oil is crucial to understanding the potential of microalgae for biodiesel synthesis. Algal based biodiesel production has an importance on carbon- neutral source of transportation fuel. The present review focuses on the characteristics of microalgae oil biodiesel's qualities on the engine performance, combustion, and emission. Additionally, discussions on the techno-economic analysis and viability of employing this fuel in compression ignition engines are also made. Finally, the future direction is explained based on the facts derived from the study.
