Fuel, Journal Year: 2024, Volume and Issue: 367, P. 131547 - 131547

Published: March 23, 2024

The impending depletion of fossil fuels has sparked a global hunt for non-conventional energy sources such as biofuels. Biofuels biodiesel can be produced using third-generation feedstock viz., microalgae. It gained huge attention it the potential to achieve goals sustainable development. Biodiesel production microalgae depends upon microalgal biomass availability and amount neutral lipid accumulated inside them. Biomass productivity accumulation vary from species but in general, are influenced by cultivation conditions (mode method cultivation) growth parameters nutrients environmental factors (light, temperature, pH, aeration, photoperiod). Lipid extracted is transesterified into biodiesel. This review discusses several factors, pre-treatment methods, extraction transesterification processes that influence quality quantity Explaining difference between direct indirect processes, elucidates roles catalyst(s) process FAME production. further about cost challenges associated with each step
